Hi thanks for sharing :). I printed this and it fits the rangefinder fine.

However the device turns itself on if there is a little bit of pressure on the back because the large round button presses against the cover. So may I suggest adding a cutout in the bottomplate for the buttons? For example a large square one which fits all the buttons in both directions so that the design stays symmetrical?

I printed this design on its side so that it will be less prone to breaking on the layer lines while inserting and thus bending the cover a bit. Used tree support for this. The corner pieces make it a bit harder to print on its side.
