Since EMT is hard to find in Germany I re-designed the hangers so they can be used with the IKEA HUGAD curtain rods (28mm - version || https://www.ikea.com/nl/en/p/hugad-curtain-rod-silver-colour-90217137/).
Designed so that two pieces (mirror one) fit on a 250x250mm print plate together with a pair of printable wall cleats.
Secure the rod in place by adding two 3mm heat-set inserts ( https://www.prusa3d.com/product/threaded-inserts-m3-standard-100-pcs/ ) or directly screw in an M4 bolt.
I recommend printing them from PETG with at least 3 perimeters.
