As an off-topic aside…the part I prototyped for the wheelchair failed after one solid day’s worth of use. Got a LOT of useful info as it actually fractured at the design weakness from the original design. I have a Mk2 that will be printed in PC-CF for the short-term fix as I wait for a milled part to come in for around Christmas time…
Right now I’m printing some replacement parts including some of the hinge bearing parts in PA6 (Nylon…)
