My collection of primarily my designs, plus the remixed track connector (for completeness), for the Carrera Slot Car Track System (Evolution/Digital 124, 132).
Note: Some of these parts are a works in progress and may need some more tweaking. This was a starting point and I decided to share as it may inspire others to give it a go. Enjoy!
update: added variant for guard rail holder as clip was too fragile with PLA
update: added Narrow variant for guard rail holder to fit 4/15 Corner pieces near joins
Tower Head note
I incorporated the track connector into the track raiser (tower) head so they can be positively fixed in place as compared to the stock push in tab which regularly slides out on casual (non-fixed) track layouts.
Guard Rail Leader note
Made to fit in my max print size of 80x80mm, so smaller than the original.
