Description
A squat stone wizard's tower that doubles as a pen and pencil holder for your
desk. A crenellated battlement crown rings the open top, spiral arrow-slit
windows wrap the shaft, and a wide flared buttressed base keeps it planted.
The bored centre well swallows a handful of pens, pencils and markers so they
jut out of the crown like spires — equal parts desk organizer and tabletop
fantasy terrain.
Size: ~72 × 72 mm footprint, ~100 mm tall. The centre well is Ø40 mm and
holds several pens loosely; the bottom 6 mm stays solid stone for weight and
bed adhesion, with a 45° countersink lead-in at the rim so pens drop in easily.
Prints upright, no supports. The shaft tapers inward going up, the twist is
gentle and the crenellations are small short bridges — all self-supporting. The
wide flared plinth lands flat on the bed for a rock-solid first layer. PLA or
PETG, 0.2 mm layers, ~15% infill; the solid base adds welcome desk stability.
Fully parametric — the .scadsource is included. Dial the tower height,
well diameter, base/top diameters, spiral twist and buttress count to taste,
or flip a single flag to swap the AI castle sculpt for a fully procedural
twisted spire.
Looks right at home next to a D&D screen, on a writing desk, or as a
characterful gift for anyone who likes a bit of fantasy on their desk.
