Super Smooth Fidget Roller

Super Smooth Fidget Roller I made this after trying out a bunch of similar models I found on maker world that left me disappointed. Everything I found seemed to be plastic only, which made the rollers both loud and “sticky” from the friction of plastic on plastic. So I did what most people with 3D printers and too much time on their hands do… remade it from the ground up to fit my needs! :) As the name implies, this gadget features a very smooth and silent rolling action and has a fine knurling texture on the rollers to provide a satisfying feel. It fits very well into the palm of (my) hand and my pockets, which along with the silent action makes it perfect for bringing to class to use during lecture. Anyway moving on, this is super simple to put together, you just need to press 2 skateboard bearings into either end of the rollers and then press the end caps into the bearings. The end caps are made to be very tight fitting so they can be a bit of a pain to actually insert into the bear
