    So to print using ABS I need an enclosed printer? I hope to build feather weights too so may want to print pulleys if possible. I'll do some more research online.

    if this is all you want it for, then yes you can, remember, that some printers are not enclosed, so you may want to stick to PLA, or build a chamber for your printer to go in.

    IIRC 1050 alu is too weak and will deform easily. 7075 and 2024 is a alot better for structure compontents but is costly. 6082 is a mid ground.

    You have parallel and series the wrong way. 2 in series wants 24v (where the negative of one is wired to the positive of the next). 2 in parallel will want 12v.
