@Drexik unfortunately, no. I sadly lack the personal funds to purchase one myself. There is no reason they should not work, however, as they are a very minor adaptation of a proven model.

@ninjaofsuburbia could you make a video of a working one to prove that the pieces you offer function correctly.
January 13, 2014, 9:03 pm
@Drexik the other parts are all custom made to suit the taste of the user, so there really are no set parts. if you look at ammnra's codex you get a sense of what they should look like, but other than that it's all custom work to suit your preference. everything is in inches, and everything has holes, attach points, etc.

could you at lest send us the dimensions that you used for the other parts

@Lawliet It is dual action, and the parts needed are listed in the description. However, you will need to customize the internal locks, springs, etc. to suit your own taste as far as the speed and touchiness goes.

Is it dual action? And what are the parts needed to complete this hidden blade?

@deadboy1313 it is indeed offered in stainless steel. Yes, most of your questions would be best adressed to shapeways. The model is made to exact tolerances, but shapeways has a machining error tolerance, but it was planned from the beginning that people would sand and polish their mechanisms to personal satisfaction. you will likely have to sand or grind every surface at least a little in order to make the pieces fit. I would recommend not using the printed gear at all. I would use it as a template for a teflon one, in order to minimize friction and deterioration, or perhaps use the printed gear on a teflon washer. I would also advise that the main drive plate be either made of teflon or teflon coated or have teflon on the bottom, again to minimize friction and wear. The locks, as seen in ammnra's design, are too small to print, and shapeways doesn't do spring steel in any case. You will, as the item description states, have to supply your own drive plate, springs, locks, and blade. the blade cross-section should be fairly obvious by looking at the end of the slides, but should look like a fat "U" with a ridge on the bottom to make use of a slot on the lower slide.

@ninjaofsuburbia coolio, and its offered in stainless steel is that correct? i guess my questions are mostly for shapeways at this point then or its just gonna be a blind order and hope the pieces fit together the way they should i guess i could order a plastic one as well and see which and how the parts fit together and which might be used where better? some sort of hybrid? because itd be alot of grease or some kind of washer system id have to use to make the gear not scratch and deteriorate the plates below... it seems, but a plastic one might not... what are your thoughts on that? and i guess exactly what have you done here just adapt it and not print or build it? im a little confused but also extremely greatful that someone has taken it as far as you have too.... sooo idk... advice? plan on starting it in september after obtaining all the materials ive already got tons of springs and wheels and cables and screws laying around our motorcycle shop, and of course sheet metal for days and welders etc, just curious what i really would need to obtain to proceed... and maybe a plastic and steel composite might work best anyone else online i might contact with other parts or even plans on how to take this one further than its available for purchase?

@deadboy1313 You misunderstood. I've never used ANY of the materials shapeways has to offer. I've never ordered anything from them. This design is adapted from Ammnra's Flickr codex page and modeled in Rhino. It uses all the same pieces as his design, but modified slightly to improve blade length. This design is rigged to use a cable, but you'd have to attach a crimp bead to catch the gear. This particular model, I believe, is 8.75 in by 2 in wide by 1 in tall, when fully assembled. It has all the same parts as ammnra's design, so by comparing the two you can find out what you need to replace.

@ninjaofsuburbia, interesting, i guess my questions go as follows, since you have never printed this in metal what draw backs have you encountered printing it in i'm assuming plastic ?, were the measurements accurate enough to line up where they need to? these are issues i can fix in metal with a welder and very little material... as far as fabricating a blade you say that it would have a slider and then the blade would slide through that particular slider for a further extension does the blade lock at the end of that ? ive seen ammnra's design and it appears that the slide and blade are one or at least held together, i also have seen how his gearing system works but using a string may not be as stable as say a cable like a throttle cable.... i have been looking into making this for a hot minute now and it appears noone truly has managed to make his design out of metal i would gladly invest the time and money it takes to produce it in a prototype form if a set of plans or measurements could be obtained... im actually not even a gamer just saw it and seeing as how my last real last name ends up strangely in the game multiple times over i figured what the hell... it was weird to trace your geneology on ancestry.com and find some link to some video game with an awesome weapon. id love to see how that could actually functionally work... call it curiousity and applied engineering... idk i guess do you have the measurements available for sale, a codex page or something like that ive heard referenced in online media? would that be for sale? or is my only option to try and piece meal it together out of random online images, and cut my sheet metal into sizing before welding and screwing and finding springs etc for the whole thing.... im down for experimentation and problem solving but it would be nice to have some kind of instructions at least to as far as someone has taken making a legit version of this...

@deadboy1313 as I told Arcticblacksmith, I have no idea. I've never worked with any of these materials before, and if you read the description you'll know what is missing from this design due to impracticality of printing. Also, this design is a little more complicated than some, as it uses a double extension, meaning the blade extends from slide, which in turn extends from the casing. I don't know if that helps, but without more specific questions, it's the best I can do.

@ninjaofsuburbia... is the stainless steel version durable or shall i ask full tang as they advertise on sword sites? i'm looking to make this for my next project as im just wrapping up a mollgabet bow and finished off a scooter customization, alot of the springs in the designs ive looked up appear to be about the same size as carborator springs, ive got alot of experience rebuilding throttles and linkages with them... i was planning on finding a set of plans for this and simply cutting it out of steel with a plasma torch and of course filing and smoothing them out but if i can find at least some of the model already printed it might make finishing it off a little simpler... idk any answer to any of these questions might be awesome and most helpful in the coming days and weeks ahead....

@Arcticblacksmith to tell you the truth, I have no idea. I also offer it in stainless steel, but I truthfully do not know the properties of any of the materials.

@ninjaofsuburbia how tough is the alumide as a housing material?
July 25, 2013, 4:53 am
@KenneyXBD This design really does work, however, as stated in the description, the locks, springs, drive plate, screws, and blade are not included. The Ammnra's Wheel is included in this model, but the lock for it is not. The reason for these parts being missing is that they are, for the most part, too small to print effectively. The blade, obviously, is prohibited by Shapeways. The springs cannot be printed, as there is no suitable material. The locks are not included because they are customized to the individual. The drive plate would be too costly to print, and would be cut from plate steel.

I am familiar with Ammnra's design and I am curious to know if this is the complete design, with the exception of the blade of course. I ask this because i can't actually see the wheel lock mechanism in your design. I am just curious does it actually work? I have seen many variations of his design, including one i designed, but very few actual work. It would be kind if you split your parts into separate images.

@nathan'sPROPS sorry, but my store is dedicated to combat grade and fully functional equipment. The white strong and flexible is good for cosplay, but not combat grade, thus, no. I'm sorry. As to assembly, I'm not sure what you mean. They only fit together one way.
June 16, 2013, 10:35 pm
Do u think u could also make it in white strong and flexible for a cheaper buy. and also do u have a tutorial vid on how to put it together?
June 16, 2013, 10:13 pm
@Drexik Then by all means, buy it and make it. BTW, if you know somewhere to get it made cheaper, I'll get you the model.
March 28, 2013, 6:41 pm
@ninjaofsuburbia i do know how it works thats why I know that this is a great design
March 28, 2013, 6:09 pm
@Drexik Not quite correct. The model is quite expensive, as you can see, and not complete. You would have to be dedicated enough to purchase the model, and in addition, you will have to work to understand the mechanism, and create your own pieces to replace those that are missing. Either way, you have to understand the design, and so doing will bring a measure of respect for the power it grants.
March 28, 2013, 6:01 pm
You do know that i can buy this and that would destroy what you stand for!
March 28, 2013, 4:17 pm
@Drexik no. I'm sorry, but no. I subscribe to the belief that if you want the model, you will have to take the effort to understand and replicate it yourself. Ammnra has some photos on Flickr of the codex page that inspired this build, and you are free to use those to try and build your own model.

@ninjaofsuburbia Could you make this downloadable?
