90 degree left curve interlocking toy train track.

I made a sharp 90 degree left turn for a young relative who only has right curved train tracks. Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: Yes Resolution: 0.25mm Infill: 24% Notes: I printed with PETG at 250 degrees Celsius, moving at 50mm/s. Use an 80 degree Celsius heated bed with kapton tape on glass. You can print directly onto the glass, but be prepared for the PETG to stick perfectly even after cooling down. PLA is too stiff; it will work, but removing it from other tracks and damaging the connecting pins is a serious risk.
