This model originated from an idea of my five year old son who wanted a kind of tree for his Gravitrax marble track to affix the base tiles to it. The initial idea went far beyond my designing skills and abilities :-) and failed also in what our 3D printer would have made possible. So, this compromise accepted with tears came out of it and looks more like a cactus than a tree but is definitely an eye-catcher and promotes kids creativity ;-).

Assembly Instruction

As base tile to be attached to the foot of the cactus you can use the 6-exit-basic-tile (or other derivatives with min. 3-holes) which can be found here: https://www.thingiverse.com/thing:3552100 or the easier to print from Speedbomb here https://www.thingiverse.com/thing:5189236.

Building a sloping track around the cactus works best by using the original sloping curves or my alternative version here Gravitrax Sloping Curves / Rails and/or the curves to be found here https://www.thingiverse.com/thing:3662227.

Have fun and let the cactus grow :-)

Revision History

V1.0   Initial upload V1.1   Heights of some branch plates modified a bit, so that its better to build a circular sloping track around the cactus starting from the top. V1.2   Diameter of the 6-hex base plate plugs and base support surface increased for better fitting and higher strength. V1.3   Stabilization gusset for lower branches added; Diameter of plate pin slightly enlarged for firmer fit V1.4   Height of some branches changed
