This clamp is specifically designed to fit “OBI Santos” boxes and their lids. Also, they allow some clearance so a stripe of sealing tape (e.g. foam tape) can be applied on the outer edge of the lid.

Depending on the material (PLA, ABS, PETG,…) you might need the clamp in wider or slimmer dimensions - just change it before slicing (height).

To create an even tighter fit, you have two options:

• shove a piece of cardboard under the clamp
• scale it a bit down
