Every Team Fortress 2 Engineers must have tool; the Sentry Gun!

This model contains all the parts needed to build the "level 1" sentry gun (approximately 8cm x 6cm x 7.5cm from it's longest points). You can also purchase the parts necessary to upgrade this model to "level 2" and the final "level 3" from the links below.

Level 2
Level 3

The YouTube video linked demonstrates the assembly of all levels along with some additional information.

Please also consider visiting my website: www.psychobob.co.uk

- This item does not come pre-painted.
- For "level 2", you need to purchase the parts for "level 1". For "level 3", you will need to purchase the parts for "level 1" and "level 2".

This is intended as a desktop model and not as a toy for children. There are small parts that can be snapped off and potentially swallowed, so please do not buy this with the intention of giving it to a young child as a toy.


IN: 3.302 w x 2.137 d x 2.463 h
CM: 8.388 w x 5.428 d x 6.256 h

@GhostlyGengar My markup is actually relatively small. Shapeways sets the base price and uses expensive industrial sized printers to produce these which are not cheap to run (so we're not talking home 3D printers like markerbots, they use printers allowing you to produce cleaner and more complex parts). They also have overhead costs to cover (electricity, staff, QC etc...). They also print on demand and are not mass produced like toy companys do, so the cost is higher. Toy companys are able to sell things like this cheaper as mass production allows to them to produce these cheaper as they are doing it in bulk using moulds. So if you're comparing this in your mind to an off-the-shelf product, they're produced in two entirely differnet ways. If you find this too expensive, all I can suggest is you either wait for a promotional time when Shapeways are offering discounts (i.e. 10% off weeks), or wait until an official version (i.e. from NECA) is released. $10-$14 doesn't even cover the base price.

@Psychobob Why is this so expensive I just wish you have the price around $10 - $14 for something that freaking small plz just lower the price for size realizes and not painted you can make it where it will be prepainted for these prices

@Alex336 First Blu turret I've seen. Awesome work, love the paint job!

My blue Sentry (Level 1), painted my own warning sticker.

@Daedalus1400 Thanks for the feedback, good to know that polishing reduces the friction between the parts. In the past I've done this to increase the friction, so I'm just leaving it here in case any one else is in this situation but doesn't want to permanently glue things togeter: On the surfaces where two parts meet and need friction to stay in place (but you don;t want permanently attached), put some super glue over the surface. Make sure to use non-viscous superglue and use a thin layer on the surface and make sure when putting it on the parts they are not assembled in any way (or it will glue the pieces together which is not what we want). Leave to dry (generally 5 mins would suffice with most super glues), try to assemble the two pieces again and see if this has added enough friction. If too much, use some sand paper to sand back some of the superglue. I know this is extra work, but combining this with the polished material should give the best of both worlds :) Thanks for buying from my shop, would love to see some pictures when you're finished with the model.

@Psychobob So I just received all three levels of your sentry in polished WSF, and you're right about the details coming through, it looks beautiful. However, some of the mating parts don't stay mated by friction, at least before painting. It's not a significant problem if the parts are to be glued, (which I intend to do), but if someone wants to interchange freely between the levels, they probably shouldn't get the model polished unless their paint adds thickness.

@Daedalus1400 I've not ordered the polished one myself, but a few people have and I couldn't see an discernible degredation in the detail when looking at their pictures nor have they mentioned anything like that. I've ordered the polished material in the past and it does come out smoother than the unpolished version certainly. Adding paint to the surface will make it even smoother if you use something like acrylic (though, like my video mentions, you need to bare in mind that this will add thickness to the model). Dyes or watercolour I doubt will change the surface smoothness

Does getting polished WSF degrade the quality of the fine details? And does painting it smooth the surface? Thanks.

@Psychobob Ok. Thanks anyway. I'll see when it'll be cheaper.

@Spazzy_Wabbit Like anything on Shapeways, they charge by the cubic volume of material used. This is just how much it came out as with a very small margin for me. Like I said, if you're finding it too expensive, all I can really suggest is to wait for a week/day when SW are offering discounts.
December 4, 2013, 3:27 pm
@Pyschobob Why would it cost so much to print it though?
December 3, 2013, 10:54 pm
@Spazzy_Wabbit Wish I could but I'm not the one who sets the base price. My margin on this is pretty small, the vast majority is the base printing cost from SW. If you're finding it too expensive, all I can really suggest is to wait for a week/day when SW are offering discounts.

@Psychobob Please make it cheaper. I don't find the object which is smaller than a soda can worth 25 dollars plus 6 dollars shipping and the paint. I want to buy it, but its just not worth it.
December 1, 2013, 5:39 pm
damn psycobob why just make them all in one insted of speending more money for a piece of plastic!!!!!>:(Still good idea!:D

@Psychobob thanks!

@3XPLO1T You're best off talking to shapeways and consulting their materials page really on your project, as it's to do with their manufacturing costs/capabilities rather than this specific model being sold. What I can say though is it would most likely cost a lot to print something of that size and you would definitely need to print it in parts as they wouldn't be able to build an object of that size in one piece. Consult the materials page for the maximum width, depth and height build areas for each material. Price is primarily based on volume, so the price difference of one piece vs multiple pieces should be negligible as long as the volume is the same.

@Psychobob i plan on making the top part of the level 1 sentry gun life sized and hollow.(putting a nerf gun inside making a arduino controlled sentry gun) It will be around 30" x 11.5" x 9.25" big...,. how much do you think it would cost to print? what if i make it in separate parts?
August 29, 2013, 6:56 am
@Psychobob Thanks a lot!

@sandinator White Strong ad Flexible takes well to most paints. I personally use acrylics (generally Tamiya, but I also use plenty of other brands without any issue), but you can use water colour, enamel, dyes etc... I tend to use off the shelf superglue from a pound shop!
August 17, 2013, 4:02 pm
Looks really cool! What type of glue/paint do you recommend for this material?
August 17, 2013, 2:59 pm
Check my model out!

@TomixNscale89 The model was made from scratch using screenshots from the game as a reference, but no model files were actually taken from the game. I did have to make some modifications to the original design's details (some were additions, some were subtle alterations and some were removals all together) in order to make this printable and functional as an upgradeable piece.
May 8, 2013, 1:22 pm
Really nicely made! I may order one of these in the future. Was this model a modification of the original Valve model? or a completely new model?

Straight out of the bag ;)
