Triple Cold Shoe with 1/4 thread and lock nut

Print the items.
Screw the nut onto the foot.
Glue the foot into the body.
Be careful. Do not fill the nut with glue.

You can use the foot with your own platforms.
The landing square on the top of the foot is 8*8 mm. Height 5 mm.

I recommend using durable plastics. Such as ABS, PETG, CoPET and the like.
