A few weeks ago I received an email from Shapeways notifying me that they were going to kill off the manual customization (co-creator) option on several of my models. Their basic reasoning was that it isn't used often and that it was a pain to maintain. Their suggestions were to either use the "custom maker" tool or enable "custom requests" and hope your customer actually bothers contacting you. (The later option doesn't even give the customer a vague idea of the price of one's design unless you have the blank model marked available for sale and are willing to take the chance that they will accidentally order a non-customized version on accident and leave you dealing with the customer service ramifications) Today I decided to edit a few of my models to be customizable with custom maker. The first time I bothered with trying it. I can't believe how poor that tool is implemented after being out for 2 1/2 years. The majority of my customizable designs were for pendants/pet tags that I manually added customized text on two sides and had printed in stainless steel based or cast metal materials. First off, the tool is a pain to use and skittish. I click on one of the squares to adjust the size of the box, and when I release the mouse button the tool will rotate my entire model several degrees in a random direction. Sometimes even flipping the model 180°. The constant readjustments to try to size and align the box is a big PITA. Second, while Shapeways gives some guidelines for the minimum distance to emboss or engrave text inward/outward for certain materials on this page https://www.shapeways.com/tutorials...email&utm_campaign=20180130-co-creator-sunset they give NO detail on what SIZE font to use. Where you enter the "font size" and "line height" in the custom maker tool it only states "min 2mm" but I can not believe that is a valid font height to use on all materials. I know from experience manually customizing numerous tags that about 3.5mm is the smallest font you can usually use for engraved/embossed text in steel depending on what font is used, and that is with using a very straight blocky and usually BOLD font. Shapeways' chosen font has varying line width and fine details and will likely trigger more "thin wall" automated rejections in customer's orders on small font heights. A 2mm tall font height might work for FUD prints but there is no way it is even close to usable in steel. With this tool being out for so long why isn't there a definitive guideline using Shapeways' chosen font for each material (Ie. a guarantee that a text height of "X" in "Material Y" will be legible and not trigger an order rejection for small detail/thin walls. Again, I know how small I can push the fonts I used in the past, but that was also after several print rejections/tests. If Shapeways is going to lock everyone in to one specific font they should provide that information. I do like that the tool allows you to enter multiple lines of text in a text box. However, there are many cases where if a person only needs to enter 1 line of text in a space where two or more lines are meant to fit, that the text could be larger so the text is more legible. A text box that has a settable maximum and minimum text height and adjusts the size on the fly while centering the text vertically would be a great improvement. Horizontal centering of text is also a no brainer and should be the default. A few old forum posts I read implied that that was, however all the boxes I created are aligning to the left edge. But WHY is there no ability to have more than one text box per model? Seriously! This makes custom maker completely useless for me on the majority of my models as most customers want their pet's name on the front and their contact information on the back. While the custommaker can project the text in a straight line onto a curved surface, there is no way to have a curved line of text, making it useless for several of my more popular models I've sold in the past. The inability to use different fonts also messes up the looks of a few models. So after a couple of hours of playing with the feature and uploading new models, I find that in the majority of cases this is going to be a useless feature for me. So now I need to reset a few of my models, change everything to "custom requests" and hope customers bother to spend the time contacting me. Until I find a better solution. I realize that all designers have different needs/situations, and that the tool might be great for some, but personally I expected a lot more usefulness out of a 2 1/2 year old feature if designers are more or less being forced into migrating to it. I still really like Shapeways, and I've sold a lot of customizable prints through the site even though it has never amounted to a large source of income. But after being a member/designer for over 7 years on this site I can honestly say that almost EVERY single time Shapeways changed something over the last 7 years I feel they have made it worse. I feel the website itself is uglier and harder to navigate, for both customers and designers. And their efforts to automate more and more have caused nothing but problems. I suspect that a lot of the "hard to maintain" reasoning Shapeways used to kill the co-creator option was because the constant changes in the model pages often broke the system so that information that was supposed to be forwarded to the designers was not showing up on the designers page. It worked great for years until someone there broke it. Honestly I miss the old Shapeways and wish that someone there would understand that "new" and "easier" doesn't always equal a better experience. Just my 2 cents.
