I tested a couple of prints at different sizes. Printing at 133% scale allowed the parts to snap together better.

I have uploaded a version 2 of the kit. I offset the faces on the road that clip into the trusses. The trusses can also be recessed into the road further. This should give a bit more room to slot in. I also enclosed the slot for the pillars so they are more sturdy. I have uploaded a full V2 kit, but I have also uploaded just the road part for anyone who has already printed the V1 kit.
