Openlock Wall w/ Hidden Compartment

This is a wall with a hidden compartment. It has the 6.0 revised openlock attachments that allows multiple attachment techniques.
There are 4 pieces. One is the wall itself. There is a cover that snaps into the wall. There are two shelves that can be placed in the compartment of the wall. The compartment in the wall has an empty shelf.
The cover slides for the hidden compartment are created to be at just the size of the openings into the wall. This means it will be tight or maybe not even able to be slid into the opening. I did this on purpose to have a tight fit. The remedy is easy. Sand the lid slides until you get the tightness in the fit you desire. Then move the lid in the opening until you get the wear in such a way as the tightness is what you desire.
One of the shelves has a bunch of potions. The other has an open book, a scroll, a writing stick and a urn.
