Prusa I3 (6mm Aluminum frame) spool holder

I printed the "Prusa i3 spool holder by n00bz0rz"
Unfortunately it didn't fit my aluminium frame, so i had to make a spacer for a tight fit and more stability.(Didn't want to waste it)
I also added a spool adapter for spools with 100mm inner diameter.
Spool adapter has a M6 threaded hole for bolt to rest in the holder( 2 x M6x40mm bolts)
A washer(s) for a bit clearance from the spool adapter to the spool holder.(i used 2)
Also made a collar(for Quick release) with a space a M4 nut and bolt
