Yet Another QIDI Q1 Pro Spool Holder Stiffener ;-)

Even simpler than my previous design and complementary to it, here is a leg to stiffen in torsion this QIDI Q1 crappy spool holder !

You'll need to print 2 small parts and cut a 7mm rod to a length of 17 to 17,5 cm (try first with 17.5 and shorten if needed).
For the rod I used a carbon tube from a broken arrow.

Slide the rod inside the holes, slide the cylindrical pin in the side hole of the Q1 pro, it must enter the hole with some friction, rotate the rod and the pin so that the flat part of the holder sits on the upper part of the stiffener. Gravity will keep all that in position...
Et voilà !

Print it in PLA or any material, no support. 8% gyroid infill. 3 perimeters.
