Marble Forest

This CAD model was designed by Oskar van Deventer, copyright (c) 15 October 2025, 14 September 2025.

Marble Forest is a variation of the Marble Castle XXL marble run. It is the same track design, but without the castle walls. Instead, tree support was used to support the track. By setting zero distance between support and track, the two integrate. A special track was needed to convince the slicer not to create tree support over the tracks. This was achieved by including an invisible "blocker" above the track that was printed with zero walls, infill, bottom and top.
