Straight path for Gravitrax System

I designed a straight piece for the GraviTrax System. I testet it and it works quite well, fits snuggly into the existing pieces and even holds on tightly to the rails.If you find anything which would improve the piece, please let me now. I appreciate every feedback because im quite new to designing stuff.I hope you have fun with it. Boost MePlease support me, if you like my model so I can design and print more in the future. Biggest appreciation if you do decide to boost me :)
