So… firstly - thank you very much for sending the model. That is 100% the thing I’m looking for.

And truth be told, my very first thought was that I should just 3D print these. Unfortunately as the building is currently in a state of construction, I have all of my 3D printing stuff in boxes. I’m considering breaking it out specifically so that I CAN print these, but thought that if I could find them I would just buy them.

Anyway, thank you again for that as it’s quite literally exactly what I was hoping for :)

Do you happen to have a link to this particular access panel that you bought?
