R1.5 cambered curve - slot car track and borders - Scalextric

R1.5 (Radius 1.5) slot track curve and borders to suit Scalextric. Also has a 5 degree camber with outer support wall built into the design. Kerb tiles are printed separately to allow different colours. "R1.5" is halfway between R1 and R2 Scalextric radii. I have printed the curve on edge in a Creality CR-10 3d printer. The print is 251mm high. I use 0.45 layer height and 0.45mm width, using an E3D Lite 6 extruder with a 0.6mm tip. Slice on Cura. Using PLA plastic. All parts are designed to print without additional support except for "clip". The curve itself will print without support if printed on edge as in the photo. One of the files says "w toes" at the end. That's the one I use. The toes keep the ends on the bed and are cut off after the print is finished. Post processing steps: - clean up track piece. - attach 2 clips with PLA welding. - sand track smooth next to slots using sandpaper glued to "sanding wheel". - attach adhesive backed copper foil to act as rails for electricity. Continue the foil in under the track. - attach adhesive backed copper foil to "connector"s. - paint border area if desired (biege in photo) - interweave coloured kerb prints (red and white in photos). Glue into channels. 19th July 2019 Added curved transitions
