Hello, sharing my latest design of insert used in camera tripod. Dims for housing slot are: 32,7*40,1mm. It won't work for every type and brand out there, let me know if you would need any adjustments.

Perfectly fits to mine, bolt used is DIN 912 M6x20mm.

The cutouts in design are there to decrease printing time.

Part of the design is the clip to carry it with the tripod when its not slotted.

Works with Cross Laser that has M6 thread insert.
