Grand Stand for Slotcar circuit

The great thing about a 3D Printer is that you can do things yourself, which can't be bought.
I have drawn this stand for my Slotcar circuit, where i don't have much space between the wall and the circuit, probably quite a common problem. It is done modular, so you can print the stand in the width you require. You can print as many middle parts as you want and connect them with the left and right ends. It will all fit perfectly together. It only takes 30mm depth space next to your circuit, but
