Monoprice Maker Select 3D Printer v2 Spool Holder Extention

This is an a longer version of the spool holder that is shipped with the Monoprice Maker Select 3D Printer v2 printer. This should allow you to use larger spools that will not fit on the factory holder.

Printing Reccomendations

Print with raft bed.
Printing with only bed supports will work just fine but there is two overhangs that could be helped with full supports. Your call. I was able to print with only bed supports.
Print slightly slower than normal if you have time. This will be holding a bit of weight so you will want good forming around the locking lugs.
You will need to do some sanding after the print. The locking lugs and bolt face are set for a very tight fit. You may need to sand things down and round some edges to get it to fit.

Sketchup model is included for tweaking. Good Luck.
