Ender 3 Z Axis Anti Wobble Coupler- 8mm Magnets, Filament Pins

prusaprinters

I tried printing out the 8mm remix here, but I wanted to make a coupling with proper filament pins. Expanded the original holes to accommodate 8mm (or 5/16") magnets- which are much more commonly available in US based hardware stores (and what I had on hand). Requires: 8MM or 5/16 Magnets (12x)1.75mm filament. I used PETG for the lower friction coefficient but anything should work just fine. 4mm ball bearings (8x)- You can take apart 2 608 (skateboard) bearings to get these. Depending on your printer, you may not get the inner alignment holes to come out. You can manually align the filament pins in each hole and then melt them into where you inserted them from to ensure a good lock in place. Since they're held in between the magnets and the ball bearings, they will naturally flex a little- so some misalignment isn't going to be the end of the world. PRINT SETTINGS: MATERIAL: ABS or PETG. 0.4 nozzle,0.2 layer height4 wallsTop/bottom solid layers- 4, 5 is better. Infill-Cubic/Gyroid- 40%Supports: none. Brim- If printing with an open enclosure.
