Ultralight spool support V3

UPDATE 8.11.2017:
Added a version for 58mm spools. So now there are 52, 54 and 58mm options.

UPDATE 12.10.2017:
Added version that works specifically with spools with 54mm inner diameter!
I just got one of those spools, so i had to update the model. Original part will work for 52mm spools

Here is a spool support that has a builtin bushing for the threaded rod. The spool support should now rotate freely without moving sideways on threaded rods and doesn't need nuts to stay in
