Refined a design by SBDecoder, many thanks!

Used for a semi permanent layout with non fixed tracks on the floor. Fits for LGB, Piko and Trainline Tracks.

Print the base and a cover and snap as many of the 1, 2 or 4 cm pieces on each of the sides as you need. 2 tracks can be connected with the double track adapter to ensure the right spacing between two parallel tracks. Now newly added an adapter for LGB bridge piers to also space between elevated tracks.

Update 29.11.2025: slightly adjusted the connectors for a tighter fit with modern printers.
