Marble Forest XXXL

This CAD model was designed by Oskar van Deventer, copyright (c) 21 December 2025.

Marble Forest XXXXL is a variation of the Marble Castle marble run. It has an extra long and windy track design. The design has two STLs, "track" and "ghost". Tree support is used to support the track. By setting zero distance between support and track, and the setting "support on build plate only", the two integrate. The ghost is used to prevent the slicer from creating tree support over the tracks. This ghost is printed with zero walls, infill, bottom and top.
