Track Helix

Track Helix (Gleiswendel) for H0 Tracks, 360 / 437.5mm radius double track - created for Maerklin M-Tracks, should also work with C-Tracks.

It takes ages to print and a lot of filament - buying would be faster & cheaper - but just because I can :)

Customizer / SCAD file allows to define height, laps and a start hight / end height to provide room for changing to the angle.

MIN PRINT AREA 210mm

...or the roundramp does not fit (printed on ANYCUBIC S without skirt / raft but a separate pre-print shape to get the filament flow)

e.g. I build a separate ramp of 3 90mm tracks with 1% / 2% / 3% incline to achieve the good 3% incline I have on my model. resulting in 5.4mm starting height - since I have my base level lifted by 4mm, the STL files loaded have a start height of 9.4mm and end height of -5.4mm (for another ramp to get the track flat)

recommended to not exceed 5% incline, and pass through height to be above 75mm
