Carrera Profi track connector replacement

Carrera Profi slotcar tracks are connected by pushing nozzles into holes and then fixing them with a small special pin (Kudos to Christian for providing these as printable 3d model as well here: https://www.thingiverse.com/thing:2737212).

The nozzles on the track break very often and then tracks tend to move apart during usage, With these replacement nozzles the track parts can be fixed again. See images below on how to make use of it.
