Wall mounted spools 28mm wooden stick - 8mm dovels

Just saw this great model and made some modifications:

1. now usable with thicker wooden stick (28 mm)
2. made the hole for wall screw bigger (now you can use 8mm wall dowels.
3. modified the hole for wall screw connection with full filament for real strong heavy connection to the wall
4. Added two holes for fixing the wooden stick, if wanted

With three holders I easy can use a 28 diameter, 2400 mm long wooden stick and hold 33 filament rolls. - Meanwhile I stabled some more roles above ;-)

Pro Tip: Make a flow dynamic and flow rate calibration, if you don't made it yet.

Other Tip: Use Torx-screws, you can fit them tight to the wall more easily. (I used 80 mm x 5 mm Torx)

Don't know english dowel and screw sizes, but with my modification you easy can adjust your needed size in Bambu Studio.
