This is a simple, easy to print spacer which goes between the heatsink and the fan for the extruder/feeder. This replaces the two 9mm x 6mm round spacers that were used at the factory.
I made this because I was tired of those small round spacers rolling down into the electronics below the bottom of the printer. This spacer doesn't roll well.
Printed using Ziro carbon fiber PLA. 225C extruder, 60C bed. Let the bed fully cool before removing the print. Designed to print without supports.
