DIN Rail Test Rack - M4 Screws

Remix of DIN rail lab bench stand by PlasticXYZ so that it is compatible with M4 screws and nuts.

I bought some cheap pre-cut 300mm aluminum DIN rail off Amazon, but they came with M4 sized slots, so they weren't compatible with the original M6 design.

Print with at least 4 wall loops, PETG preferable, but I've printed in PLA+ and haven't had any issues.

Changed mounting holes from M6 to M4.
