PREFO SlotCar - R90/270 Curve Half Radius

This additional curve is compatible with the classic PREFO slot car track and has half the radius of an original PREFO curve type R90/270

Ideal for expanding track layouts, creating tighter curve combinations, or as a replacement part for damaged segments

Optimized for FDM printing (PLA recommended)

Standard PLA black (track), PLA white (center strip), and Support for PLA/PETG were used, printed with a 0.4 nozzle and the adjusted print profile

Print time is approximately 1.42h After printing and removing the support material, I disassembled the conductors from defective track sections and reused them These were adapted to the curve and secured with UHU HART glue

The recesses on the underside are provided for this purpose

If this PREFO model has helped you or you would like to support my future slot car tracks and expansions
