Fix 12.06.2026: wave shapes are really wavy now.
Different rail types, all compatible to each other. This pack contains only rails! Additional parts are required to assemble tracks. This model pack is an unofficial add-on for STEMFIE project.
!!! Some rails (vertical*) requires both original AND mirrored parts. Some other rails (shift*) are better used with their mirrored sibling. Use MIRROR option in your printing software because mirrored models are not included to the pack.
In Vertical style each rail is a single part. Print in pairs, connect using 0.5 units spacer between rails.
Different corners (30°, 60°, 90°, etc)
Flat-style, beam-style and vertical-style rail types
Slopes
Construct and fine-tune a dead loop
OpenSCAD model code is included
Dimensions:
Track width = 1 Block Unit (BU)
Track height = 1/2 BU from building plate
Rail thickness (at top) = 1/8 BU
Rail thickness (at bottom) = 1/4 BU
Don't forget to download parts from original STEMFIE construction set. Also I recommend to use my other parts (plates, axle connectors) for scaffolding:
Plates Pack will be available soon: threaded plates, plates with side screws, etc.
