I got the idea from thingiverse, but redesigned to get better hole edge distances to be a little beefier.
This is a 40mm fan bracket for the REPRAP prusa mendel v1 that attaches to the x-axis stage on the side opposite of the belt.
I will need to make a nozzle for the fan still, maybe just cut out some clear packaging plastic and bend it into place as a duct? It worked well for the printers’ electronics fan shroud.
added a light too to see the hobbed bolt condition.
