This will hold 25 rings from Necromolds. You'll need Qty:6 M3 x 35mm screws, and nuts. I think you can use 30mm screws if you don't use the screw covers. The Logo is an inlay that needs to be glued in. I used a textured build plate on the box and a smooth plate on the logo to give some textural contrast. I designed it to be the same size as the expansion box Call to Arms.

Here is a link to the tinkercad design if anyone is interested in changing it up.

Credit: A lot of people have remixed this rugged box and I have taken elements from a lot of them to combine into this. I've tried to give credit to the original design of the box. the latches came from https://www.printables.com/de/model/39729-tool-box-parametric.
