This is yet another Gaslands Death Race gate design, with a 15.5cm gate mouth. This is slightly narrower than the 18cm recommended width, so you may want to scale up the design to get to an 18cm gate mouth. Personally I prefer a narrower gate for more potential mayhem.
This design is inspired by other box girder style Gaslands gates, but I wanted a more 'Rock Concert' feel. It's detailed with pieces from another of my Things here: https://www.thingiverse.com/thing:2864136
You will need to print one of each STL file. The 'GaslandsText' file is optional, and only required if you want to include 'Gaslands' on the gate. This font is 'American Captain' from dafont.com, available here: https://www.dafont.com/american-captain.font if you want to create your own text.
For assembly tips, please examine the photo. Glue is required - I use super glue. The horizontal sections need to be glued together, and then glued to sit on top of the vertical girders. The vertical girders have obvious tabs that the side supports sit in.
If you make something interesting with these designs, post a link please. I enjoy seeing what people do with my designs.
