This is a simple insert that fits in a Multigrid bin of size 1x1x0.5 from the MultiBoard universe.

I did not include any way of locking it in place in the design, so to not have to modify the original bit itself, I decided to just drill a small hole in the bottom through the bin into this insert and threaded a M2.5 bolt in place. This keeps the insert from moving around or popping out. Easy peasy.

No special print settings needed. I used 0.2mm Standard setting in Bambu Studio which defaults to:

Layer height: 0.2 Walls: 2 Infill: 15%
