I've recently started using DIN rails for prototyping my Arduino projects, and I love how a good stand gets everything up off the desk. The other stands I've seen all expect you to screw the rail to the legs but I prefer a more adaptable, screwless solution, so I designed one for myself that uses a clip-on mount, and dialed in the tolerances to make it a good, tight fit.
Printed in PLA with 0.3mm layer heights, 3 perimeters, and 7% infill.
For best results, print the Gripper Test piece first and try it with your DIN rails. Then dial in the print settings before printing the entire leg.
Took inspiration from the stand here (by Phil Klaus), and the clip-mount here (by Selphb).
