I’m in NSW Australia, and we are a metalshop, I’ll check out what is available as far as 25mm OD tube goes, wha would be the ideal material/wall thickness? We have facilities to cut to size etc. and I’d be happy to pass it on to Aussies at cost.
BTW, what approximately in Australia is an all up cost for a final unit by the time it is all assembled, just for CNC work? I want to cut 3mm thick styrene sheets, ideally 1370×760 sheet size.
