Skeleton Track - Straight

I always felt like most train tracks out there waste too much filament without any benefit. So I designed my own.Even with just 2 wall loops and 15% infill they are quite strong. If you want to make them really strong, just use 3 wall loops and more infill.I plan to add other tracks (corners, switches, bridges, ramps, …) soon.My settings:Nozzle0.4 mmMaterialPLA Matte (Bambulab)Layer Height0.2 mmWall Loops2Infill15%Top Surface PatternConcentric I have added the most common sizes (in our collection at least) as STLs:60 mm105 mm145 mm215 mmChangelog: v3: Update connectors (use same length) and reduce fillet for better bed adhesionv2: Use same geometry as my other models (track profile, connectors, measurements)
