So my mother works at a cabinet building company, and I thought I should check with her for prices of sheet melamine / scraps etc to see what they had. She sent me these pictures of some drafting shelves they had that boss man said I could have no charge. They are made with melamine, and all the shelves are removable & adjustable. My thoughts are after measuring and installing heat is to secure the shelves with screws (adjustable doesn't seem like a good idea when wanting to keep snakes secure lol) She's going to send me measurements this afternoon, but said they are approx 24" deep and ranging in height from 3'-5'. What do you all think? Snag them up and work from there? I'm really liking the shorter rack with counter top on top.
