    I was reading about YASFF opensource SFF case build project where he 3D prints the corners into which the sides slide in and the top and bottom is screwed down. Here is a picture of the 3D printed corners

    My idea is a similar cross section to the YASFF corners (remove the void and optimise for extrusion) sold in set length that allows the consumer to cut to their own lengths to suit their own case design.

    After looking at the experts adding their expertise in threads like the laser cutting thread, I wondered if anyone might have experience with Aluminium extrusion moulding? looking at bunnings for mass produced mouldings they seem to be as low as $10 a meter. i'm guessing the Die Moulds are expensive to make, though one informational site i was looking at quoted as low as $500.

    anyone with experience able to give a better estimate on cost and minimum batch size?

    It's been awhile 09' but I seem to remember 0.5T or 1Ton minimum order.

    I'm surprised there isn't a corner type extrusion available to purchase, I have seen some chinese sellers selling a case with them but they weren't willing to sell the extrusion when asked.

    yeah it seems like there might be a niche market for them. perhaps less now that people can 3D print them.

    looking at videos / animation of the extrusion process, the Aluminium boules looked like they could weigh the 0.5 ton, so it would make sense for a minimum quantity

    500kg is general minimum order for a couple of the suppliers I deal with but I know that there are extruders in au that specialise in lighter profiles that have much lower minimum order sizes - 80kg is in my head but I'm not certain on that
