THE PRINTED SECRET — CODEX AND OBJECTS
Single-colour edition | 27 September 2026 | v1

For a printer using one filament. Painting is optional.
The original coloured project is unchanged. This single-colour revision updates
only the decorative wheel centre. If you already printed the kit, reprint only
04-wheel-centre-retainer.stl; the other physical parts are unchanged.

CHOOSE ONE ROUTE — DO NOT PRINT BOTH SETS

A. Flash Studio / native project
Open codex-and-objects-single-colour.3mf as a PROJECT.
It contains two plates: the Codex, then the five reusable tool pieces.
Every material region uses filament 1; face painting and the purge tower
are disabled. The saved Creator 5 Pro profile remains. Check your actual
printer, nozzle and filament, then slice again. No G-code is included.
Old colour thumbnails were removed; your slicer can regenerate previews.

B. Your own printer / portable files
Import these six numbered items using millimetres at 100% scale:

01-codex-portable-single-colour.3mf           Print one assembled book
02-wheel-base.stl                          Print one
03-wheel-screw.stl                         Print one
04-wheel-centre-retainer.stl                Print one
05-ruler.stl                              Print one
06-grille-engraved-portable-single-colour.3mf Print one assembled grille

The portable 3MF files contain geometry, not a printer profile. They do
not require a colour printer. Keep each file's component regions aligned
as ONE object using ONE filament; do not split or auto-arrange the regions.
The book's opening cover must remain in position for print-in-place hinges.
STL files do not store units: choose millimetres, never inches or auto-scale.

Why not STL for everything? Flattened book/grille STL exports introduced
tiny mesh defects at former material boundaries. Those files are excluded.
Their portable 3MF versions preserve the verified component geometry.

WHAT CHANGED FOR SINGLE COLOUR

All existing book/wheel/ruler relief and engravings are retained. The
grille's formerly flush colour markings are recessed 0.30 mm on their
respective faces so they can be read without colour and painted if desired.
The grille outline, windows, existing body and internal central core remain.
This is a separate monochrome grille edition; do not replace the original
coloured version with it when following colour-specific instructions.

WHEEL CENTRE REVISION

The underside lettering has shallow grooves just outside its original boundaries:
0.35 mm wide and 0.30 mm deep. The letter faces stay flat, with no embossing.
The decorated upper face, outer dimensions and fitting geometry are unchanged.
Keep the flat reverse on the bed; inspect these grooves in a fresh slice.
Keep paint out of the fitting surfaces. Check seating and free rotation.
Jon approved this design/download on 27 September; no new physical print of
this outlined edition has been reported.

GAME INSERTS

The interchangeable middle wheel rings come with the individual games.
Their absence here is intentional. Use the matching ring and assembly
directions in that game's print pack. A wheel with only these three carrier
parts is not yet a configured cipher wheel. No game-specific ring is chosen
by this general pack.

PRINTING AND OPTIONAL PAINTING

Use the supplied upright pose for the book, and the existing flat underside
for the grille/tools. Do not scale a piece to force it to fit the plate.
Check supports, bridges, first-layer adhesion and print-in-place clearances
in your slicer. The native settings retain 0.20 mm layers, 0.25 mm first
layer, three walls and 10% infill, with brim/support off; these settings
have not been freshly sliced or physically validated for this derivative.

If painting, follow the included geometry previews and the game's marking
instructions. Keep paint/primer out of hinges, threads, sliding surfaces,
magnet pockets and ruler/grille openings. Do not fill the markings or alter
their shapes. Let the coating cure before assembling moving parts.

CHECK YOUR PRINT

Digital native import, mesh checks and geometry previews were verified.
Actual slicing, a full print, marking readability, strength, assembly,
storage and wear still need checking on the exact edition and materials.

LICENCE

Personal printing only. You may print these files for your own non-commercial use. Do not redistribute or sell the files or printed copies. Commercial makers need a separate written agreement with The Printed Secret. Downloading does not grant commercial rights.
