I'm keen on boarders, barriers, walls, fences. I played with the scale in one direction and managed to print an R2 that conforms to the R3, but that results in changing the angle of the ends preventing them from fitting flush to each other, and results in an odd length. I also found some of the old scalextric piano boarders- which are great! But, the author has only straights, and R2 curves inner/outer boarders. I'd really like to find a printable model of the old yellow Dunlop tower/bridge that Scalextric used to produce. My username on Thingiverse is 'USNSCPO') There's a Dunlop Tire Bridge I want to try. So far, I have a number of things saved to test. 5 years ago, I built the Dunlop tower/bridge, tire bridge, and score board tower, but the humidity in my basement hasn't been kind to them over the past 5 years. I have all the paper buildings from downloaded which are amazing. I'm currently trying to build them out of foamcore, which isn't bad, but, well, looks like paper/foam. ideally, something like the old school Le Mans garages. I don't have a lot of depth to play with, therefore, I'd just like to have the front portion of a pit garage. I'd really like to find a pit garage fascia to place along the back straight-away of my track. I'm still evolving my layout, but once I'm done, I'll need people.
