Spool holder redesigned - RzR

thingiverse

This is a universal spool holder using skate bearings. It is a great style of spool holder for people how has an enclosure for their printer. The design has been carefully made to fit perfectly between the parts and to be printed using a resolution of 0.35 with a 0.4 nozzle but anyway it will probably work using another resolution. I also recommend to print it using 3 layers on the perimeter to get strong columns. You have to print the part 4 times and 4 skate bearings to be able to make 1 universal spool holder. Watch it fit together: https://youtu.be/pJDJmUl4MLE EDIT: I have added what I call "drag spring". It's to prevent the spool from spin too much when the extruder pulls the filament. It just adds a bit of resistance. Watch how I put it in: https://youtu.be/-Y49ox4xa2E Skate bearing measurements: -Inside Diameter: 8.00mm -Outside Diameter: 22.00mm -Width: 7.00mm If you have any other improvement possible, please let me know.
