Desktop Marble Run

Basic components for a desktop version of a classic toy are made from simple parts. I utilize ballbearings from an old bike wheel that measure approximately 6.5mm in diameter, yet any size between 6mm and 8mm should be suitable. It is recommended to print the pieces lying flat on their sides as shown in the photograph, with supports enabled. A moderate amount of support is necessary, but it results in a better-fitting final product. You may need to clean up the tops of the pillars if your printed item appears messy, however, optimal slicer settings can minimize this requirement.
