My Son and I love to play with our Gravitrax sets but quickly ran out of Hight-Tiles - there are quite a few solutions on thingiverse but they either need multiple steps to print or/and don't blend in well with our existing pieces ... so we came up with this no-support needing single step print design that is also fairly material efficient (probably will make the top layer thinner in v2). We like tipple height - but it would be easy to re-slice to any height. Just repeat the 10-20mm section as often as you want... enjoy!

02/22/2020: added parameterized OpenSCAD version You can now change the height of the stack (and lots more) to your liking. Don't like the tapered look - change CHAMFER to zero ... Implementing the top fillets was a major pain - wanted to see if i could do it. The original design was in fusion 360 - will add those files once I have them cleaned up.

02/22/20202: Changed rotate_extrude(angle=60...) to angle=360 followed by intersection with triangle to avoid issue with old customizer versions (like the one used by thingiverse)

PS: more designs to follow - a large funnel and a neat motorized elevator for Gravitrax to be posted soon ... check out https://youtu.be/BKRZ39W47l8 for a sneak peak. You might also spot the printed height tiles in this video - there are about 20 of the triple tiles used here.
