Mega Size Spool Holder

I just finished this design so I could print with those cheap spools that have a giant hole. Printing it now. Will update with results.

Update 05/25/18: After printing and testing I found that the spool holder is good for only the biggest of spools. The threaded rod part is too short to reach through the middle of small holed spools, and the flanged area is obscenely big. Not that it's so big that it wouldn't work for all spools, but it's bigger than it needs to be so it wastes plastic and printing time.
