Half-round spool arm adapter for LulzBot TAZ5

thingiverse

I kept examining the stock spool arm for my LulzBot TAZ5, noticing it seemed misshapen and would cause unnecessary drag due to its square shape while round spools were used.\nSo I rapidly designed an adapter in Blender that simply sat atop the existing arm - no need to replace it entirely.\nThe initial version lacked the extra ridge, causing the spool to slide all the way up against the frame. Adding this ridge kept the spool firmly in place.\nSo far, this solution works perfectly fine - results may differ for others.\nNote: This might be an engaging first project to learn how to create a parametric version for different sized spools.\nThis adapter is specifically designed to work with spools that have about 2 inches of inside diameter.
