Finding a non teflon coated aluminium pot with a heat capturing coil for lightweight hiking is impossible last I looked.

Just removing teflon from stuff is a huge pain too, it's dangerous to burn it off, I might try and sand blast the Teflon off the one I have. I have to research how bad that is, probably makes way too much toxic microparticles. But it really shouldn't be so hard to find food appliances and cookware not coated in this crap.

Blender has a decent cam processor add-on. Solve space and openSCAD are other very good parametric CAD programs.

I was burnt by fusion 360. Had some of "my" designs locked in the cloud when they spent 2 weeks and a dozen emails trying to "fix" my educator access. The fix they really wanted was my credit card details. I refuse to use or teach anyone to use that ecosystem now.

You can get close enough in most situations by looking at bolt size, thread pitch and the material. Some level of intuition and knowledge about what each fastener needs to do is also helpful.
