FlexFlexRail

Mod of FlexRail with Knobs on one and both Side.

I have the Idea to use my empty Filament spool for building another Track
for the ball track

Add a "Distance" Part so that enough height between two FlexFlexRail.
This Part is similar to ft 38246 "Bauplatte 15x15 1Z rot" but with 12x10mm
(and a Bad Knob 8-( )

Fischertechnik Steel Balls have a diameter of 12,7 mm.

The Knobs are longer so that no Support Structure is needed
but round knobs are better for slope of the Rail

Streched the Rail to 17mm (ft 15mm) wide outside
and 229,99 mm length (My maximum 8-( )

New Version 0.133 (10 Knobs on both side an it´s possible to glue extra Knob )

Add a minimum Angle Block (Halter) for connecting two FlexFlexRail
with a angle of 5° for the groove.
Angle Block with two cavitys for insert the FlexFlexRail when Angle Block is
fixed (e.g. inside a empty filament Spool)

(To do :Negative Angle Block for mounting on the Outside)
The Height of 58 mm came f
