Spool Holder Wall Mount

I made this spool design for mounting the spool on the wall close to the printer. Works great with my Ormerod 1.

The spool size I use is 1 kg pla with following dimensions:
Centerhole:Ø32 mm
Spool Height: 95 mm

EDIT: just realized the endstop was flipped, so I reflipped it - now it should print nicely:)

UPDATE: I've now used this for a couple of weeks , and personally find that turning the spool so the filament leaves at the top gives the best result. (opposite to the way it's installed in the picture).
