Simple to print Gaslands gate. I made this as an exercise in making something with (albeit very simple) joints. Your printer won't have to be super dialled in, the joints are quite generous. The sign bit just glues on to the gantry, it was too fiddly to arrange otherwise, but I'll keep working on it. It also gives you the option to stick other bits on for a more post-apocalyptical feel.

Gaslands_gate.stl is the basic gate. The other files are various components, and alternative billboards and signage, including a Start and Finish.
Gate_numbers.stl should fit into the top of gate_top_numbered.stl, so you can have numbered gates from one to six.
The New version of the gate Base now has a direction arrow on it.
