Ideally, all tools should be moved to a generator type system, as the electrical requirements for heavy machinery aren’t going to cut it with just batteries. Since people want the full crafting experience, then hotplates, food dehydrators, and anything else that requires a lot of energy should require a generator, or a vehicle-hookup. A hotplate, for instance consumes as much energy as a microwave.
To make this less messy you could update the tool quality system to check for charges like so:
{
“type” : “tool_quality”,
“id” : “GENERATOR”,
“name” : “generator”
“min_charges” ->check in the recipes(generator should be on the have the gen-quality show up, and should consume charges while it is on).
}
Only select places would have generators, such as hospitals, retirement homes, resorts, military, lab and police. Some homes might have a generator, especially in rural areas.
You could probably use a 3-D printer to print cheap disposable guns
However:
Just the idea of a 3-D-printed lower receiver bothered him; if the ring that held on the buffer tube and stock (the big loop at the back of the receiver) were to break, he pointed out, it could unleash a large and powerful spring inches from the shooter’s face. “It scares me,” Rynder said.

Other things:
Tool and Die experience to make the molds and you are going to need a mold for each part(one for the receiver/barrel/parts/stock).
Drill-press, simple pipe guns look like they could be made from a cordless drill. Oh and the drill presses probably are going to hard to move.
End mill- in the article I read, the author was told a end mill is needed, as a drill-press isn’t able to handle the lateral stress.
Grinder machine
Vice
deep-hole gauge, barrel hone, etc(can be simplified to gunsmithing tools)
Workbench
Polisher.
Blueprints-ideally one for each gun to allow the gun-maker to make one from scratch without hurting themselves
Sanding tools
chemistry set.
Welder
"Dremel".
You can make the process simpler with a CNC machine.
