MakerGear M2 Printer Spool Holder

This works great with the cheap spools unsed by various vendors; the hole in the top of our cold end's ABS was being eroded by the
tension with these cheap spools using the original MakerGear holder, and that doesn't seem to be an issue
with this holder. However, some spools (e.g., from MatterHacker) have too small a center hole. I found that a 3/4" dowel just barely fit through the spool and designed end caps with an internal structure to firmly hold the dowel ends so it doesn't walk out -- http://www.thingiverse.com/thi... . Incidentally, I think the MakerGear spools still work better on the original holder, and you can have both mounted simultaneously using the split mounting brackets you have in this design.

Project can be made using only items shipped with your m2 3d printer.
PLA was used for my prototypes and it works just fine.
All Models should be ready for slicing in the correct orientation.
A g-code file is included for printing the six required parts on a M2 Printer. It will print the set in under 3 1/2 hours.
It is recomended that you use 1/2" schedule 40 PVC pipe for your uprights and crossbar. You can get a 4 foot long piece for $1.25 at a home improvement store. If it is not available then you can use the supplied optional-tube.STL to print them.
