Nema holder for Ultimaker quiet retraction

thingiverse

This excellent Ultimaker quiet retraction by Maxy can be further improved with my design, which adds less noise than the wooden backplane while also including a fan holder for the NEMA 17. Print it at a layer height of 0.15, shell thickness of 1.2, and density of 100; secure it to the wood with M3 1.6 mm screws and to the NEMA 17 with an M3 2mm screw.
