Since building always lacks exactly one right pillar for the marble run Kullerbü from Haba, this is a file to print the pillars of size 3, 4, 5, 6, 7, and 8.
Thanks to Bender0815 who posted the model, my contribution is a fine-tuned print profile for the Geeetech Wood Filament. This filament is an inexpensive wood filament that works very well for this model.
