Retractable Desk cupholder

Update 1/3/2026I had gotten a few reports that the retractable cups were over extending past the internal guide rails and getting stuck. For people that come across this issue I've uploaded an alternate print profile with the guides extended which is “a1/p1p/and larger extended guide rails”If you come across this issue with your print, try giving this profile a shot, thanks! Update part 2.I've redesigned the cupholder to now include a cutout for coffee mugs. Along with that I've done away with the extra “screw parts” needed and the design is now just 2 prints. You can find the Coffee cup version here. The new design is slightly larger to allow for various coffee mug sizes .https://makerworld.com/en/models/881453#profileId-835663 UpdateAdded updated model and instructions for A1 Mini.
