Board games / Original games
Watchfires — a stacking board game of beacons for 2–4, all printed
A stacking game of beacons for 2-4. Every ring you place is a watchman who counts the towers he can see.

Boxes & storage / Organizers / Drawers
Carousel Drawer Tower — Stacking Swing-Out Parts Organiser
A modular desk organiser of pie-wedge bins that swing out around a central post. Stack as many tiers as you like; a wide fillable ballast dish keeps it planted. Fully parametric OpenSCAD.

Boxes & storage / Organizers / Baskets
Parametric Stackable Storage Box (1×1 to 5×5)
Stackable storage drawers with stud-and-hole interlock — they tile sideways and stack vertically with each other. 25 ready-to-print sizes from 1×1 up to 5×5, with both door orientations for every rectangle, plus 2 height/fit specials. Parametric SCAD source included — change pitch, height, or footprint to derive any size you want (the SCAD goes well past 5×5).

Boxes & storage / Keepsake boxes / Geometric
Rhombic Dodecahedron Box — one part printed twice, magnets sealed inside
A 64 mm rhombic dodecahedron that opens at its equator. ONE STL, printed twice — the halves are congruent, not mirrored. Eight Ø4×2 magnets are enclosed mid-print: no glue, nothing visible, nothing to fall out. Stacks like cannonballs.

Boxes & storage / Organizers / Baskets
Stackable Lattice Basket — 4 Sizes + Parametric SCAD
Cross-stackable lattice baskets with cone-peg corner posts — any basket stacks onto any other basket. Four ready-to-print sizes from 5×5×5 cm cube up to a 20×12×8 cm tray, plus an optional cone-foot leg accessory. One open short side per basket so you can reach contents while the stack stays put. Parametric SCAD included — override basket_l/basket_w/body_h to derive any size; corner-post + peg geometry is shared so derived sizes still cross-stack with the printed ones.

Desk & office / Electronics / Stands
Stackable Server Rack — Tool-Free Mini-PC / NUC / SBC Shelf
A modular, tool-free rack for mini-PCs, NUCs, SBCs and other small servers. Each level is a honeycomb-vented floor on four fat corner posts; levels self-stack on cone pegs (no screws, no hardware) and four wide feet lift the whole tower off the desk for airflow. Print one floor per device, four feet once, stack as tall as you like. Parametric SCAD — resize for any box.

Desk & office / Organizers / Paper Notes
Stacking Letter / A4 Paper Tray — modular, honeycomb floor, 20 swappable nameplates
A classic 4-post stacking in-out tray for A4 or Letter paper, sized to fit a 256 mm bed. Paper sits landscape and overhangs the low open front so you can grab a sheet one-handed. Stack as many tiers as you print — corner pegs drop into the tier below. Comes with a pack of 20 clip-on nameplates (IN · OUT · TODO · URGENT · BILLS · CHAOS …) plus a blank one to write on. No screws, no glue, no supports.
