RC Racing Barrier

Here is a barrier system that was originally designed for 1/28 scale/mini z/RC28 etc racing. I didn't design the original body of this print, however it seems to have been removed from the site so I cannot give props to the originator. Originally each piece was designed to be screwed together with 4mm nuts and screws, however while painstakingly screwing them all together, I started to think of a way to connect them without screws and came up with what you see here. I also added corner pieces that have a kurb to keep racers from wanting to barrel into them as well as pieces that can be mounted to the mat with the use of 4mm screws. The Harbor Freight mats will need 30mm long screws. I also added an under-mat mount so that it spreads the surface area out as to not tear out easily. Printing: Barriers: I printed the barriers with 3 layersUndermount: printed solid for strength (probably overkill)
