Gravitrack straight&curve rail

Combination of straight (1 block) and curved (1 block, 2*60 deg) rail provides help in case where you can't put a column of spacers and classic tile in the middle. It reminders me movement of knight from chess game :-)

Rails fits firmly into the tile, so it does not fall when a marble runs onto it. On the other hand it allows maximal slope 20mm in both directions (2 regular spacers).

Printing:

• No support needed! I recommend to use strong bridging.
• It works well wit 0.15mm layer. Other layer thicknesses has not been tested.
• There is version with integrated minimalistic brim. It should be sufficient. If anybody needed bigger brim, then download version without integrated brim and use slicer brim.
• Left and right options are just mirrored, slicer can do it.

My thanks goes to @MK_Design for original model of rails in my remix.

Diclaimer: This is in no way official product of Ravensburger. This model was designed as compatible with Gravitrax although it is not granted. It extends capabilities of Gravitrax game and I recommend to purchase original Gravitrax set to extend it by the model.

Combination of Kurve_2x60_Schraege_0deg and Schiene_Laenge_1_V1.

Modified to allow print without support.
