(total print time on medium speed 1h 36mins for 16mm model and a faceplate)This controller holder will only work with Xbox One controllers (the 360's protruding battery pack stops it from fitting in this design) but it can also hold a mic/headphones. There are two designs for the controller holder, one only fits on 16mm thick boards( which is very common for furniture) and the other can be used on any edge but will need to have something on top of the part that actually rests on the shelf to keep it in place which makes it perfect for a bookshelf or game shelf(In the 4th pic you can see it's not sitting flush with the board, that is due to warping and not the design) . There's also faceplates that can be glued on the front to give it more flare, there will be a Xbox logo one and P1 through P4.If your 16mm model doesn't fit your 16mm particle board shelf-1st make sure that your shelf is in fact 16mm thick. 2nd make sure your printer is properly calibrated if that doesn't work leave a comment on how much bigger or smaller the gap needs to be and I can upload an updated model. The screw holes are 4mm wide.
