Modular hotwheels wall and/or table display

Modular hotwheels display. You can screw them to a wall and stack them as high or wide as you want. Credits to p4mp3r072 for the orriginal design Improved / changed from original: Removed big connectorsI found them hard to connect and take appart again, with setting them in place and attaching to a wall they dont have a major function anymore, so replaced them with small locating lines. No need for different versions for left, right, top and bottom because the pins dont stick out that muchReduced depthWith the removal of the bigger pins the room in the back was not necesary anymore. Made screwhole biggerThe original screwhole was not big enough for the standard screws I would use (4mm), now it is.
