Has anyone had any success without using the shredder and just using finely “cut up/diced” plastic pieces? I doubt I’ll be able to build all the machines, much less afford the parts so I’m looking for another way. If anyone has anything at all that might help, please post!
Theoretically you can use a regular blender for shredding plastic. Then heat it up in an oven on a tray on a piece of baking paper and place the hot plastic into a wooden mould made of separate pieces, which can be quite rough. Again with baking paper lining so that plastic doesn’t stick to the mould. Close the mould and put some weight on top of it.
This is the simplest way to get square plastic pieces that could later be machined or used otherwise.

Hope this was helpful
I think I’ll be able to work with square pieces for now and build my way up to an Extrusion or Compression machine.
I’ve tried a hole punch but it’s super rough on your hands and it doesn’t yield much plastic. Taking some safety shears and cutting up plastic is quicker and less rough on the hands but will still make you sore
