This is a spool holder for the honeycomb wall system from RostaP. This is compatible with my [BaBo duo] riser modul in the honeycomb version but also for any other application with honeycomb wall system. Printed bearings in size DIN625-608 are included, but you can also use real ball bearings if you have them.
There is an additional filament guide that works with the Bambu Lab connector. (See image.)
Optionally, the spool holder and the filament guide can be screwed to hexagonal plates from the rear.
Big thanks to printingbuddy for testing.
