Filler filament holder PAX mount

I've discovered a model of screwless spool holder by RandumbPrints. But I already had a Filler filament holder, so I've mixed them (rescaled, combined). Printed mine from PLA, but I recommend PETG as it gets hot inside of PAX. I recommend increasing the wall count to 3 or 4 for additional strength. Printed it with inserts down with organic supports in PrusaSlicer and certainly don't recommend it. It works, rough surface is not visible, but it requires a lot of supports and takes time to accurately remove it without damaging inserts. Try to print it vertically with a brim and organic supports to hold inserts.
