Set of three propane dust covers with diagonal retention strap holes

Our Scout troop needed dust covers for the propane-related items, but also needs to not lose them. I remixed three designs and added additional material to two of them to make a 45 degree hole through them. The troop version has our troop number printed in the plastic, so if a retention strap fails we at least have a chance of identifying it and getting it back.
Remixed in Tinkercad.
Files are oriented to print without supports.
I used orange PET-G, 3 walls, 20% gyroid infill, .2 Speed on a Prusa MK4.
