Gear Spinner Keychain

<p>My take on a fidget spinner keychain. Designed in Fusion360 and printed in 3D Fuel Pro PLA on my MK3S.</p> <p>There are 3 body options:<br/> "Body" uses M3 Brass Heat Set Inserts<br/> "Body Without Inserts" does not use M3 Brass Heat Set Inserts<br/> "Body Without Inserts And Hanger" does not use M3 Brass Heat Set Insets and I eliminated the keychain hanger part.</p> <p>If you use "Body", you'll need 2 M3 Brass Heat Set Inserts, 2 Skateboard Bearings and 2 M3 x 8mm Socket Head Cap Screws.</p> <p>If you use "Body Without Inserts" or "Body Without Inserts And Hanger", you'll need 2 Skateboard Bearings and 2 M3 x 8mm Socket Head Cap Screws.</p> <h3>Print instructions</h3><p>I usually print these in 3D Fuel Pro PLA.<br/> 15% infill is fine because the gears will automatically print in 100% due to their dimensions.<br/> .15mm layer height is a great "Goldilocks" resolution.<br/> No support necessary.<br/> I design in Imperial (Majestic) Units. If you aren't using the latest PrusaSlicer, you will probably have to adjust scale to 2540% because 25.4mm is equal to 1".</p>
