Spool Holder Shelf Bracket Adapter

Just above my two 3D printers are some wall mounted shelves with brackets. Tired of trying to get behind the Makerbot the change the spool, I took an old piece of 1" PVC conduit and created an axle on which I can put spools of filament above the printers.

Print them in a fairly solid form so they are strong enough to bear the weight of the spools.

* print 6 bolts
* print 2 end stops
* print 2 clamps
* print 2 bracket adapters

OR

just print the one file that has all the parts
