Just out of curiosity, and without predudicing customer/supplier confidentiality, what is the order of magnitude for this type of work? Are we talking tens, hundreds or thousands to get something made?
Background: Not model engineering – I designed a towbar bracket for my bike in Fusion 360 and had it 3D printed for £15. It might be strong enough, but if not then can I give the same file to a foundry and have them make me one in aluminium without it costing more than the bike itself?
