I took off the top layers on the “middle bit” and selected a sparse infill pattern of Honeycomb in Bambu Studio.
I didn't want it completely hollow to the bottom, as I want to use it to dry after cleaning the glue off the bed, so the honeycomb should act as a nice catchment.
Printed at 0.2mm layer height in Overture light blue.
Cheers to debren27! Applied same licensing :).
