About this 3D model

This one is for my specific, but can be easily used for another kinds. Dimension of my scale 15x237x13mm. I made the holder 20mm shorter to save print time and material. Works great anyway. Standard Bambulab X1C settings are used, I have used PETG and printed both parts - one of them is symmetrical. Simplest method is to glue them to the place with double-sided tape, so I haven't used screw holes.
