It is possible! I plan to get this design done and then do different covers that you could get.
that would be neatI'd go for an 'ARM' or 'ARM SYSTEM' on the cover!
Awesome. I think I'd go with just "GT".Messed around with some personalization features in shapeways! This is not final! Just showing off what can be done. Basically you will have a text box on the product page where you can input custom text on the front of the cover. There will be a character limit but you will be able to personalize it if you choose! You can also leave it blank if you wish.
Once the prototype arrives and I test it out (and it passes) I will be posting links in this thread to the product page!
