Carrera Curb "Randstreifen"

Hi,

this curbs (outside shoulders, how carrera cals them in english) are compatible with Carrera Tracks (1:32 and 1:24 / Same track for both car sizes).

The curb is only 4,9cm wide, and therfore half the size of the original Carrera parts.

With the secound part you can get the full size 9,9cm shoulder.

It is wide enough for my 911 GT3 in full slide. The La Ferrari an 918 Spyder still can go wider.

The part is printable on smaler printers like my i3 Mega.

Part List:

1/2 straight shoulder (2 pieces)

1/3 straight shoulder (2 pieces)

30° curve shoulder (4 pieces)

V1.0

2 parts of 15° for one 30° curve.

5cm wide

Full circle diameter (inside) is 79,5cm

The R3 Curvs have a 79,2cm outside diameter. So there is a little bit of play to compensate bad connections and printvariance.

the connector is only partial compatible to the "original" curbs. Some of them has a connector port of center. I will fix that later. i wanted to use them now. :-)

black How I Designed This ===================

Build with Fusion 360 from scratch.

Draw a circle with the full circle curve diameter. Add an offset of 5cm.

Cut the circle in 30° and 15° pieces. Some extrusion, some magic ;-) and done.
