Modular Breadboard Kit V2 - small box module with lid (with STEP file)

UPDATE - The models uploaded currently have been modified slightly to help reduce some unnecessary overhangs which will reduce supports needed. The current version is D12H, and that will likely be the final version.

I've not printed this, but thanks to Rubi for posting a make, it appears this will work as intended, so changing this from work in progress.

This is a small box module for the Breadboard Kit Version 2. It will require:

4x M3 brass inserts
2x M3x16mm screws (I think 12-16mm will also work). I think it would be best to use the round headed screws.
2x M3 washers

Two of the inserts will be used for the lid hinge, and they go on the body side of the hinge. The other two inserts go in the body of the box as well, and are used to mount it to the rest of the breadboard kit.

I'd suggest printing the hinge on one of it's thin side to minimize supports.

You can find the rest of the modules and a better description of the "Breadboard Kit V2" at the link below:

There is a double length box module here (which is also untested):

I suggest trying tree supports with this, they are usually easier to clean up.
