About

I'm trying to design things that serve a practical purpose.
Mostly film making gear and parts for CNC machines.

For my designs I try to also publish
* the original file (usually Alibre/Geomagic)
* technical drawings with dimensions
you can always ASK ME to EXPORT TO OTHER FILE FORMATS.
STEP, IGES, ProE, ACIS should be no problem.

I consider STL to be a lowest-common-denominator output-only format! It's not a format to be edited.

This is not a Steadycam. It's a shoulder rig. It's also completely off balance ass all they weight is in front of the shoulder and no counter weight behind it.

That's not Solidworks. That's Geomagic/Alibre and the design changes the inner diameter, so the outher one stays consistent. So I can't make a larger one.

BTW, the real thing would also not have bolt heads with an electric potantial other then PE sticking out. Certainly not ones with different potential next to each other where any random object can short circuit then.

The DIN is not related to any government. Not even directly to legislators. It's engineers. The people requiring proper material to be used are not government or legislative either. They are worker's accident inssurance. These connectors are used for 1.5mm and thicker wires. So we're not talking about small current applications. As I said it's also making bad contact and damaging the wires to twist the tip of a bolt onto stranded wires. (I realise that on other continents solid wires are more commonly used for .) The melting point is obviously determined by the fact that it's used in an FDM printer. CAD modelling and 3d printing a mold for polyurethane would be more apropriate. However 3d printing this and using bolts most likely purchased in small qualitties from a home improvement store is serveral times more expensive then simply buying the real thing for a few eurocent per strip.

No metal clamp it closed around the leads. Instead they are twisted by a screw that turns. Thus the contact area is low and the cable may easily be moved by the clamping operation to lower the contact area further. The material is a plastic with a very low melting point and no mixed in agents to make it less combustable. Thus the resistance and risk of breaking wire strands in their ferrule is much higher and the resulting risks are not mitigated. All to safe a few cent on a proper, DIN/ISO compliant terminal block that you can get at every corner.

This sounds like a terrible idea safety-wise.

I think 45° tappered edges would have worked better because at no point do you have a >60° overhang as with your rounded edges.
