The Infinite Archive - Gothic Infinity Book Nook

📖 Description

The Infinite Archive is a gothic-inspired book nook that creates the illusion of a vast, endless library using an infinity mirror effect. Stone arches, repeating corridors, and carefully layered depth draw the eye far beyond the physical limits of the shelf. A large gothic window acts as the primary light source, glowing through transparent PLA and backlit by a hidden lithophane LED panel, while a subtle flame wall effect positioned below the panel adds warmth and movement deeper in the scene. Concealed wiring paths, an integrated electronics drawer, and internal mirrors keep the exterior clean and architectural while supporting multiple lighting and power configurations.

🛠️ Build Instructions

This project supports two build paths. Decide which configuration you want before printing or purchasing electronics.

Step 1 — Choose Your Build Configuration

Option A: Motion Sensor Build

• Automatically turns on when someone approaches
• Requires a motion sensor and additional wiring
• Best used with continuous power (wall power or a power bank without auto-shutoff)

Option B: Manual / Always-On Build

• Uses a simple USB power switch
• Fewer components and simpler wiring

Drawer faces with and without a motion sensor hole are included.

Step 2 — Acquire Materials

In addition to printed parts and electronics, you will need:

• Cyanoacrylate (super glue)
  • Used for recommended and optional structural bonds

🪞 Acrylic Mirror Cutting & Fit

Cutting Methods

• Guillotine paper cutter
• Utility knife + straight edge (score and snap)

Back Mirror

• 150 mm × 180 mm
• thickness advertised 2 mm, measured ~1.5 mm

Side Mirror

• 116 mm × 180 mm
• Same thickness as back mirror

Front Two-Way Mirror

• 131 mm × 180 mm
• Advertised 0.04 in thick, measured ~0.75 mm
• Optionally you may use a 3mm thick two way mirror and print the appropriate side-wall plate in the print profile

The body supports mirrors up to 3 mm thick.
For thicker material, cut mirrors slightly narrower to fit the recessed pocket.

🧪 Adhesive & Assembly Notes

Super glue is used selectively. Many parts press-fit or hold in place with clear tabe, but adhesive improves durability.

Recommended Glue Joints

• Drawer → Drawer Face
• Front Facade → Lobby Floor

Optional Glue Points

• Lobby Floor → Body
• Side Walls → Body
• Back Mirror → Body
• Side Mirrors → Body
• Infinite Floor → Interior
• Infinite Bookcase → Infinite Floor (seats in a shallow recess)
• Infinite Column → Interior

Do NOT Glue (unless you really want to)

• Lid
  • The lid is intentionally removable for servicing electronics or wiring.

🎨 Filament & Color Guide (as used)

Structural / Stone

• Bambu Basic Black
• Panchroma Matte Fossil Grey (box & lid)
• Elegoo Marble Cement Grey (walls / light floors)

🔧 Assembly

Prepare your path

Wiring with sensor. The flame LED from Amazon comes with bare wires, I connected them to a PH2.0 wire I sacrificed from the backlight kit.  You can also order one by itself to sacrifice.  Use the drawer face with hole

Wiring without sensor

If you dont want the motion sensor, you can just use the switch that comes with the backlight kit.  Use the drawer face with no hole

Place the power bank and sensor/wires in the drawer, pull the wire through the hole of the floor.  Unfortunately this power bank will shut down after some time.  The motion sensor works great with continuous power, there may be alternate batteries that do not intelligently shut off.

Step 2

Use one or twoM2.6mm screws and mount the led panel into provided slot.  Note there are mounts for the power distribution board for potential future expansion

Step 3 placing mirrors

These mirrors are advertised as 2mm, but they measure to about 1.5mm  there are slots in the walls to handle up to 3mm thick

tape is useful to keep things from moving, glue can work as well.

Step 4

window wall placement

tape is useful to keep things from moving, glue can work as well.

Step 5

infinite floor placement

Step 6

infinite column placement

tape is useful to keep things from moving, glue can work as well.

Step 7

watch your wires

Step 8

place the two way mirror here.  The issue with this thickness (advertised as .04" , measures at about .75mm, is that it is very flexible.  I am trying thicker material (3mm) but I will need to cut down the sidewalls and lobby floor to make that fit.

Step 9

dont forget to place the infinite book case

Step 10

main hall placement

Step 11

gently place the flame in the flame wall.  watch those wires, you could tape them so they fit in the channels/chase.

Step 12

the fire wall fits into the hall arch bookcase (use the appropriate plate for the thickness of your two way mirror)

Step 13

place the other side wall.. it fits into the main hall as well

Step 14

Place the front facade.  you can glue it down.  I originally had it key'd, I lost the keys and painted the part.  I will go back and add that for simplicity, but for now just use a little glue.

Put on the lid on the thing!

All done :)
