Topographic Marble Run

myminifactory

The Topographic Marble Run is a new twist on the classic marble track. Press down on the flat tile track to give it the height it needs to work as a functional marble run!  I've decided to list this particular marble run free of charge because the track piece is a fairly tricky one to print and I don't want anyone to pay for a piece they can't print. That being said, if you enjoy this marble run I have lots of other great tracks for sale and I'd really appreciate your support!  Requires a 3/8" ball bearing and (optionally) 2-4 compression springs 7/32" x 1-1/2" The Base piece is printed without supports, the Track piece should be printed with supports only touching the build plate. Be very very careful removing the supports from the track piece, definitely requires pliers and a bit of patience! I'd do 12-20% infill for both parts as there can be a fair amount of pressure being pushed onto everything.  If you like my work and would like to see more of it, follow me on Instagram @coolthingsbyjacob, and please take a look at my other models available on here!  Thank you so much, and happy printing!
