Summary

Changes from the original:

• Added spot for a blade fuse puller
• Added baffle to help keep voltmeter wires tidy
• Beveled screwholes to allow for a bit of material displacement
• Added indents on lid for 8mm Little Rubber Feet

I printed this in PETG for field toughness, but PLA, ABS or other filaments would be fine too.
I used supports (for the fuse puller cutout) but if your bridging settings are up to it you can probably get away without.
