Mounting plate for label holders on GoMaihe boxes

I used the following model to create label holders for my filament boxes from GoMaihe https://www.amazon.de/gp/product/B08JTH2NZJ/ref=ox_sc_saved_image_1?smid=A3P2F8UC64D34X&th=1

Since I store the boxes alternately upright and upside down, I wanted the label holders to be exactly in the center. Specifically, in the center of the X and Z axes! To achieve this, I designed a simple mounting plate so that the label holders can be glued with hot glue onto the cereal boxes, no matter which way they are oriented. It was important to ensure a nice alignment. The plate is very simply designed; a simple print quality is sufficient for mounting. If printed from PLA and dropped, the centering pins could break. So, be careful!

P.S. If you use hot glue (which in my opinion is perfectly sufficient), then roughen the boxes slightly in the adhesive area beforehand with 120 or 180 grit sandpaper. The label holder has enough grip, so it does not need to be roughened
