Silica Trommel (bayonet lock, customisable)

To be inserted into the center hole of a filament spool. Model relies on the slicer to create breathable walls. Just set numbers of top and bottom shell layers to zero, outer wall loops to 8 or so and choose an infill pattern and density to your liking. I favoured Gyroid, Cubic and Honeycomb, printed with layer height 0,2 mm in transparent PLA.

OrcaSlicer 2.0.0 messes up the top layers of the round walls slightly (still usable, though), so I went with Simplify3D (Gcode for Bambu Lab P1S included, transfer via FTP or SD card).

Outer dimensions: ⌀ 50 mm ⨉ 40 mm
