This is a gridfinity bin for a Vinca caliper model DCLA-0605. Probably fits many other generic 6" calipers.
The bin has 3 slots for storing extra batteries if needed and I added space for your fingers to take the caliper easily.
The caliper will sit flush inside the bin so you can stack more bins on top. It has magnets sockets underneat.
There is a 6x2x3 and a 6x2x4 models in the print profile. They fit in a X and P series build plate sizes.
Just choose what plate you want to print according the desired size.
