Minimalistic filament spool holder small footprint 4 OneUp / Printrbot etc.

thingiverse

This spool holder measures 43mm in diameter with a maximum footprint of 60x60mm, perfect for a variety of uses. It's extremely easy to modify or slice, and an extra ball bearing can provide added stability. If you need extra grip, simply place double-sided adhesive tape underneath the base plate. I sourced one ball bearing from a bicycle and was impressed with how small it is, making it simple to integrate into your design. With this spool holder, you can create a rotating tower by using adapters - specifically one that expands the diameter from 48mm to 43mm, which I found suitable for Sainsmart filament spools. Unfortunately, these spools are notorious for their poor construction (such as cardboard) and can struggle with standard vertical spool holders. But with this adaptable solution, you'll be able to store your filament efficiently, making the most of your available space. The design itself is versatile, ensuring that even users with smaller printers like myself (using a OneUp Model1) or those who use the Printrbot won't face any challenges during the printing process. I've kept things simple by using standard PLA settings and avoiding overhangs or support structures. Remember, achieving perfectly rounded circles may require some fine-tuning of your printer's belt tension for the X and Y axes - just make sure it's tightened enough!
