About this model

A simple modular marble run kit for 16mm glass marbles, with potential for further parts to be added. Specifications as follows: Each piece has a height of 30mm, with 18mm diameter channels.

This fits into a socket in the bottom of each piece which measures 21.6mm diameter and 1.5mm deep. The props have a top prominence measuring 9.6mm diameter and 4.5mm high, which fits into a socket 10mm diameter and 4.5mm deep (with a domed roof for tolerance and printing ability). All created in Tinker…
