Filament Spool Roller

thingiverse

This is a versatile spool roller that can be easily adjusted to suit different spool sizes. It relies on 8mm skateboard bearings for smooth operation. Frustrated with the limitations of the frame-mounted spool roller on my Ender 3, I designed this one to be simple and hassle-free. Its modular design makes it easy to mount anywhere or customize to your preferences. - Print the wheels at 102% scale to ensure a snug press fit. For a tighter fit, try printing them with less than that. I've included a quick test print for the bolts as a courtesy. Due to minor variations in print quality, you may need to adjust the size by a percentage up or down to achieve a perfect fit. I'm glad I could share this design with you, and I hope it enhances your 3D printing experience. Thanks for checking it out!
