JJW Play Tray Clone

thingiverse

UPDATE 29-Jun-2023: I've updated the tolerances on the track to account for both size balls. The bearing is now able to roll around the tray's track x5 times per the specs of the original JJW Play Tray. Please use the new "playTrayV2" file. I will keep the legacy 12mm and 14mm files up for public use. ORIGINAL: 02-May-2023 This is a clone of the Play Tray, originally designed by JJW and Shannie. This was a metal tray which you can set spare screws in while building something on your desk. It is meant to be complemented with a ball bearing that you can fling and spin around the outside of the tray. The group buy for this tray ran from Jun-01-2022 to Jun-14-2022. I did not know about this product until I saw it on keyboard community pages, so I recreated this tray from scratch for everyone to enjoy. I've perfectly designed this tray to have a fillet that is exactly 14mm to surround the ball bearing on the outer diameter of the tray, and the inner diameter is tangent to to the ball, giving it perfect contact to the tray. I, however, only own 12mm ball bearings at home, and these sizes are pretty common if you have marbles laying around if you don't have metal ball bearings. Either way, both sizes can easily be found on Amazon. I've created two trays to account for the different 12mm and 14mm ball bearing sizes. Enjoy! NOTE: PLEASE do not redistribute this model for profit/sales. I respect the original manufacturers, and I do not want to see this model taken and reprinted for mass production. Print this for your own personal use, not for resale.
