About this 3D model

Couldn't find a Nema14 fan mount, loads of Nema17 ones that I couldn't be bothered to resize. So I made my own. cough sort of cough. I took the Nema 14 Motor cover, chopped it up in Google SketchUp and attached it to the 40mm fan base. I scaled the whole thing up 1.01 in netfabb Studio cause 1st print of the Nema 14 Motor Cover wouldn't fit (more my printer than anything it tends to print a tiny bit smaller than it should) hmm I think its too tall as well added a shorter version that just misses the shaft Nema 14 Motor Cover 01 ( Conseils ) / CC BY-SA 3.0 40mm fan ( trth ) / CC BY-SA 3.0 the holes are a bit too big for mounting the fan :/ added a ver with smaller 2mm diameter holes hopefully so an m3 bolt/screw can go in without a nut no holes for fan stalling yet
