FlipKey / Keyrambit (for 6005,6803 & 6804 bearings)

thingiverse

This is a home-printable version of the flipkey / keyrambit as seen on tik tok. It allows the user to spin their keys in their fingers (similar to a karambit) and can be used as a fidget toy / keychain. Originally, this design only supported 6005 bearings since that is what I had on hand, since then I've added support for 6804 and 6803 bearings, which bring the whole thing to be smaller (and more keychain-sized) and lighter. In order to assemble it, you will need a bearing that corresponds to the size of the STL downloaded (either 6005, 6804 or 6803) bearing, simply push the bearing into the hole (depending on printer tolerances, you might have to print it at different scaling). If it's just a tad too tight, you can always use a mallet to hammer the bearing in.
