These pillars (posts, or technically, bridge piers; I learned others call them spacers) have been designed and printed because my son got an amazing new toy from Ravensburger: GraviTrax marble run. And of course, during the holidays, we needed more piers to get the marble run built the way we wanted.. we needed.
So here they are: Extra piers to support the original GraviTrax hexagonal base plates.
Optimized for printing time, not for beautiful design. Needed them desperately!
My original version without tunnel turned out to be a bit more stable (high marble speeds). So I added them here too.

Print with big end down! (Use/play with big end at top)
I print them with the Cura settings:
Wall line count = 3
Top/bottom count = 3
- 0.3mm height at 200% line width
- 0.2mm height, 0.4mm width (=nozzle diameter)
- 60mm/s print speed, except:
- outer walls: 30mm/s
Play. Maybe some sanding could be required to smoothen the foot (small end) not to brak the original GraviTrax cardboard "play ground"
First real thingi with Fusion 360
As a hobbyist, I downloaded Fusion 360 some time ago and applied for the educational/hobbyist 1-year license. But then almost did nothing with it.
Ravensburger's GraviTrax cried for home made parts, and so I started drafting something like the original pier plates, only 3 times as high. Printed an eternity. We needed more, and faster, so I started a new one only applying plasitc where absolutely needed.
Here you are!
