Spoolholder Qidi Tech X-Max

Because I was not very satisfied with the standard spool-holder of the Qidi X-Max, I designed a new one, where the roll change is very easy.
Additionally you need 2 round steel bars with 6mm diameter and 218mm length.
Furthermore I recommend 4 ball bearings e.g. https://www.amazon.de/gp/product/B07H925MF3/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
for the rolls. The other rollers are for the case, that you want to save the ball bearings.
