I seem to get more of this shit done when I feel accountable to not be a boring dickhead to anybody watching. I don't need you to actually WATCH, I just need to feel like you MIGHT be. Whether or not you like watching a guy smoke a pipe and build guns is up to you.
I need to know what is going to go wrong with this, so I'm testing the worst possible setup to see what it looks like. Background music courtesy of Roger Radio.
This recording is of a theoretical interesting idea for a gun, in freecad. This is not a real gun, this doesn't exist, but theoretically somebody could complete a gun design like this. The thumbnail is another project like this, but not the same gun. I tried to do a stream of this but failed- have a gander at this recording instead.
This is a pair of printable adapters to turn a registered SBR type mp5 mount tube at the back into a usable stock. Please only print this if you are allowed to have it. it's made for the 30 mm rear tubes with the single detent groove down the bottom, if the stock rear you print is not staying vertical the "make it usable now" fix is to use a shim in the slot (there's a vertical slot so the mounting bolt squeezes it onto the tube you put it on) to index on the bottom of the bufer. There are two versions- a basic grooved butt pad printed in place, and a version with a completely flat back intended to be printed and then have a conventional rubber butt pad on as you would with a normal wood stock, and the original freecad file is included as an educational reference for anybody that wants to learn to make or customize their own things. Assembly instructions are to use as you see fit.
This is the same carbine, in a half-unfolded format, WITHOUT complete modeled parts on the interior surfaces yet ("there are blobbed-in rectangular blocks standing in place of finished parts to demonstrate functional form factor"). This is a normal part of my development process, the blobs get refined into finished parts as standard components that can have their geometry checked across multiple modeled formats (open, closed, half folded, all parts of the duty cycle of the bolt/barrel reciprocation, all parts of the trigger assembly duty cycle, etc), and part of why I like to use an old version of sketchup that lets me do this on my local machine quickly and easily.
