This is a simple Cull tag bar that can hold up to 7. Countersunk screw holes sized for M5 Screws or bolts, Whichever suits your application the best.

I highly recommend using some sort of weather and climate proof material such as PETG, ASA, PA, Etc.

Have at least 4 Walls And Bottom/Top layers and 20% or higher infill for best endurance. Better be safe than sorry.

Please comment any suggestions that can improve the design top better help the community in the long run.
