Solidoodle 50mm Fan Mounts on PVC-pipe

50mm fan mount which can be attached to a 3/4" PVC-pipe (like the original spool holder one on the back of the Solidoodle SD3 printers). I use the fan to cool the controller and/or the 12V PSU.

I made two variants, v1 and v2. Both can use an M5 screw and nut to lock it in place on a 3/4" PVC-pipe. V1 is stronger but V2 uses less material and is my favorite. :)
