My lulzbot Mini can't print anything beyond 3x3 or 1x4, so the stock 2x4 nippers (https://thangs.com/designer/ZackFreedman/3d-model/Gridfinity%2520Nippers%2520%252B%2520Strippers%2520%252B%2520Pliers%2520Racks-61120) won't fit.
I like the idea of the custom 2x2 rack (https://thangs.com/designer/LengAwaits/3d-model/Gridfinity%25202x2%2520Three-Bay%2520Nipper%252C%2520Stripper%252C%2520Plier%2520Rack-67528) but I needed more bays.
I fiddled with the original parametric source to make a 5 bay 2x3.
In order to make this work, the first/front bay is very shallow. It fits a pair of small handled pliers well, but won't fit an ergonomic/thick handled tool.
I also removed the screw holes through the Gridfinity base (magnets are still in place) because they ended up interfering with the racks.
