Another 40mm CPU Fan Mount for Printrbot LC+

thingiverse

This is a simple fan mount for your Printrbot LC+ print head, which utilizes a 40mm CPU fan (sourced from an old computer). You'll need the following hardware: (2) 4-40 x 3/4" Phillips Head Screws with nuts and flat washers; (2) 6-32 x 1 1/2" Phillips Head Screws with nuts and flat washers; a 1/8" drill bit, and a 5/32" drill bit. After printing and cleaning up the mount, proceed to drill fan holes at 1/8", and mounting holes at 5/32". Attach the fan using 4-40 hardware, then install the bracket on the print head. Modify the 6-32 nuts by grinding down one edge for clearance with the printer's back hardware, replace two bolts in the head, and mount the new 6-32 hardware. Route the wiring, plug it in, and start printing. Ensure that the fan does not obstruct the printing process before proceeding.
