STOP: DON'T PRINT THIS!! It's a waste of time and filament.
I designed it for the fun, for a competition, but it should be fully redesigned to make it work, and I am not going to do that.
I print it on a Bambu X1 Carbon, in PLA tough, with a 0.6 mm nozzle and 0,18 layer height. Knob, screw and measure block to be printed upright, the end piece and the runner should be printed with support. See the 3mf file.
I use cyano acrylic glue, works wonders and is very cheap.
The author marked this model as their own original creation.
