This is not a conversation about guns. This is a conversation about items that have withstood abuse that are near unbreakable.
Some items I have heard referenced as AK47 of:
Gerber MP600: It’s a multi tool
Old Thinkpad Laptops
Mag lights
Toyota Hilux
At this point, I’d also just say Ender 3 printers. You can get them for a hundred bucks now. They’re not as fancy as the newer 3d printers with auto-leveling, remote printing, dual extruders, etc. But they get the job done just fine.
My Ender3v2 always has some new problem to deal with. It’s cheap but it’s a pain in the ass.
Interesting, I have the opposite experience. Even with my half assed tinkering it prints just fine. Slow but fine.
