Bespoke slots

As I understand, a stl is a program file, you can use with a 3d printer to print stuff. I was hoping that someone here already made a conversion track, borders etc, to be able to print it.

Good day guys. I have a nice super 124 track. I would like to use it as a small club track here in the Northern Cape, South Africa. Do any of you perhaps have any stl’s to use with this track? I would really like to incorporate Carrera track with it, but any stl’s would be great. I can’t find any super124 tracks, here in South Africa. Best regards

Good day Please try to help me, I’ve been collecting slot cars for 35 years, just got hold of a few 124 Scalextric tracks, and thinking about using it as my home track, I would love to get my hands on your stl files, hope by now you have the inner and outer borders for the 124 outer track, as well. And will it be possible to print a conversion track from Scalextric 124 to Carrera Track? I am thinking of using 3 of the 4 lanes from Carrera, till I can find more 124 tracks. Best Regards
