Every print, including the ones that failed.
A failed print sends the design back to the drawing board; a good one marks the parts of the design it used as proven in that material. Both are written down here.
Printed the redesigned coupon in PLA because no PETG was on hand, and it works really well. The user did not say which hinge width was printed; both parts are listed. Confirms the estimated 37 mm span and 8 deg pre-tilt snap in PLA. Long-term creep when parked in one state is still unobserved.
Printed the bistable_coupon and it failed. The left and right hand brackets must be connected, and the switch arms have to pass through a hole that tunnels through the frame. Cause: cut the plunger slots clean through both rails, so the frame was two separate side brackets joined only by the living hinges. Material not stated; a frame design failure, not evidence about the mechanism or its hinges.
Printed and it works well. The Ø16 bores with the diamond lattice, wrapped caterpillar and reared head. Confirmed by the user as this build, in PLA.
Measure it, describe it, and we'll draw it.
Requests take a few minutes. You'll get the design and a price back before anything is printed.
