This Spool Rack is the perfect addition to your 3d printing setup! Accepts a 1'' wooden dowel. The print profile allows you to choose your own infill pattern so that you can customize it to your specific style and needs! It is a fast print at only 1.5 hours on the p1s! If you are not using the print profiles provided, the way to achieve this effect is by removing all of the top and bottom layers, so that the infill will be exposed. I increased my wall count to about 7 to still have a strong part. No supports needed!
