# Ender 3 Stock Spool Holder with Bearings by Zakazy Remix A remix of the Ender 3 Stock Spool Holder with Bearings by Zakazy. ## Inspiration / Design Choices I originally liked his design the most, but after printing found the tolerances were a little too tight, and printing the parts was slightly difficult. I started from scratch using his design as a general reference. - Shaft - Added notches to bearing housing to improve the tolerance issues - Added cones to the interior bearing area to improve printability and ability to easily remove bearings - Decreased overall length (Will probably increase this but did so to decrease print time) - Rod - Decreased the diameter to improve tolerance issues - Added bulges to bearing mount points to keep the fit snug. - Switched from a threaded screw design to the stock fastener style - Opted for a coned approach on the fastener section to again improve printability without the need for supports. ## Print Suggestions I had no issues printing the final design. For the Rod I ended up printing that with 8 wall line count and a 40% infill only because I had concerns that the rod being so small in diameter may cause issues with heavier spools, but in all my original testing i was at a standard 2 wall line count and 20% infill and had no issues. For all my printing i stuck with the .2mm layer height which was the goal of my remix.
