I remixed the nice original design of Schrittmotor (https://www.printables.com/de/model/401255-skadis-caliper-mount) because I like it a lot but it does not fit my digital caliper.
Modifications:
Print instructions from the original model:
It can be printed without supports, but it is a little challenging because of the overhangs and the quite small bottom surface. Please print it with the hooks facing down (see slicer screenshot). If in doubt, use a brim (and/or supports of course). When printing without any supports, turning down the print speed is recommended (the model does not take long to print anyway).
Additionally I raised the bed temperature to increase adhesion, in this case 80 °C for PETG.
