31/32/33 each hold one piece, so "-x4"/"-x16" read as if the files held 4 and 16 copies. Renamed to -print-4 / -print-16 and rebuilt the Bambu Studio projects. The MakerWorld upload package lives in publish/ (copies, not in git). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
sandTable
A 12" kinetic sand table that draws patterns in sand. A steel ball rolls under glass, pulled by a magnet on a polar arm underneath. The case is about 12.5" across and 5" tall. The parts are 3D-printed for a Bambu P1S and designed in SolidCraft.
Building one? Start with BUILD.md: parts to buy, what to print, assembly in order, wiring, the first run and troubleshooting.
sand-table-v3.solidcraft: the printable design (latest). Bodies namedREF_*are bought parts, modeled for fit only.sand-table-v2.solidcraftis the previous version.print/v3/: STL files for every printed part of the v3 build. Use this set. Print the two fit tests (00,00b) first.print/README.mdhas the parts list, print notes and assembly order; the older folders are kept for reference.software/: the pattern player. Start it withpython3 -m sandtable webfor a web page with a library of designs; it drives the table from a computer over USB and erases between patterns. Seesoftware/README.md.pcb/: an optional custom controller board (ESP32 + 2× DRV8825, FluidNC) that fits the Uno standoffs, with PCBWay order files. Seepcb/README.md.sand-table-v2-assembly.step: the v2 assembly, for viewing in any CAD tool.design-notes.md: how it works, dimensions, parts to buy, hardware list and print settings.sand-table-v1.solidcraft,mechanism-mockups.solidcraft: earlier layout and mechanism studies.
