The screw mechanism broke the first time I tried to use it. I guess it can still be used with a quick clamp, though it would be awkward. Original print was 25% infill. I will try reprinting the screw at 100% infill with some PETGCF and update.
Quick and easy print with no supports, no fuss. Took a while to get the M3 screws started. Now just need to knock up a mounting plate and I think it could use some knurling on the handle but it is great as is for some light soldering. Great design. Printed at 250mm/s on my A1 with Elegoo Rapid PLA +.
