New features and fixes in the MiniMarbleRuns generator. RSS feed
Better multi-colour prints and new guides
- Multi-colour 3MF files now open in Bambu Studio and OrcaSlicer with each part on its own filament, instead of everything on filament 1.
- New “Leave room for prime tower” setting (on by default) keeps freeform runs narrow enough for the purge tower that multi-colour printers need.
- Bambu X1 and P1 runs now stay clear of the wiper corner at the front left of the bed. The corner is shown on the 3D bed, and there’s a separate Bambu A1 option that uses the whole bed.
- Fixed freeform fins that could end in a point hanging in mid-air where a track passed underneath. Slicers reported these as floating regions.
- Fewer “floating cantilever” warnings in slicers: long openings under the track now have a level bridge instead of a shallow sloping underside, the start funnel sits fully on its walls, and the short stub behind the start has a fin under it.
- New guides: how to 3D print a marble run, free marble run STL files, and pages for spiral, zigzag and freeform runs.
- The gallery loads faster and shows runs straight away.
- The 3MF download and print guide now explain how a track colour that differs from the structure adds filament swaps on most layers, and how to keep purge waste down.
