About this 3D model
The old triangle or classics tracks from Scalextric, SCX are made of soft plactic and tend to bend over time or at uneven places. This is especially the case if cables re running underneath the track. This simple clip can be added at different locations of the straight tracks. t creates a downforce and rectifies the track. The tracks are elevated by about 1.7mm, which is not ideal, but I could not identify other options so far. On the positive side, this cables can now run underneath the track without problems.
