A 3D-printed part to mount a 30mm fan in front of the Y-Axis Motor of a tinyboy fabricator.
It has a strong fit on the slanted side of the extrude head carrier.

Tinyboy Fabricator










Lay flat on the long right hand side.
The snap fit sits quite strong on the 3mm acrylic wall;

While the snap fit works well with PLA, I recommend to use ABS or another material that has better long term stability when exposed to heat. The first model I built from PLA warped over time and let the fan hanging downward by ca. 4mm after 1 month of frequent printing.


Use two small 2mm screws to secure a 30x30 mm Minifan.

Place the hook over the side wall of the gantry, so that the fan is perfectly vertical and directly infront of the Y-motor.

How I Designed This

FreeCAD 0.16

It took a while of adding and removing and padding and cutting, until it fits.
