A simple caliper mount for Skadis boards. It is designed for analog calipers and will probably not fit digital calipers.
As mentioned above, 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).
The one shown in the picture was printed with Prusament Prusa Orange PETG, using no supports but a little brim and the speed tuned down by a few percent while printing.
Update: It is nice to see this model being given a shot with quite a lot of different calipers with different shapes. In some cases, the holder does not fit the calipers (or at least not well) so they hang leaning or you guys had to do some work to make it fit. So I did two things: I added a drawing with at least some of the part's measurements so you can better assess whether the part is going to fit your calipers. Also, I added a .step file so you can better edit the model, in case only some small adjustments would be needed to make the holder fit your calipers.
