Ender3 Filament Roller Guide Snap On No Tools Fidget Spinner Bearing

thingiverse

This is probably yet ANOTHER filament guide, but I couldn't find one that met my needs. My space is somewhat limited width-wise so I have to top-mount my spools. The other filament guides out there are great, but some of them just seemed too fragile or unwieldy. I wanted a top filament guide with a fidget spinner bearing/roller and it had to snap on without tools or disassembly. Unfortunately, I couldn't find one that worked for me. This design borrows the "clip" and dovetail from this filament guide: https://www.thingiverse.com/thing:2917932 It also borrows the roller, axle, and tool-free, disassembly-free snap-on style of this lower guide (I'm still using this one for my lower guide). My upper guide pairs very well with this thing as it's designed to do: https://www.thingiverse.com/thing:3081063 This uses a standard 508 fidget spinner ball bearing that snaps right onto the axle. Depending on your print accuracy, you may need to trim the axle to snap the bearing and roller on. Once you snap the roller and bearing onto the axle, there will be enough clearance to slide your filament up or feed it through, but the filament shouldn't fall off the roller or escape. *There are 2 versions of the upper roller mount.* One is compact and quick to print, and it works. The other has a 55mm offset for better alignment with the lower guide and extruder. I'm using the offset version because it lines up with my lower roller. *I recommend printing either mount with bed supports.* I don't claim to be smart or a good designer. This is something I built in about an hour using Tinkercad.
