Fujifilm disposable lens with adaptable focus

This model is a remix of the original Printile design from Printables. I’ve added a missing locking groove to ensure the lens stays securely attached to your camera. 

Turn a used disposable camera into a unique lens setup with this adapter. Pair it with your favourite Fujifilm film simulation to create beautifully nostalgic photos with a distinctive character.

Getting a disposable camera

Don’t have one? Try your local camera store; most likely, they have used disposables that have been developed and give them away for free.

Printing tips

• Recommended material: PETG (PLA also works)
• Use a dark filament for the best image results

Assembly Guide

Preparation & Safety

• Safety Warning: Disposable cameras contain a high-voltage capacitor for the flash. Even without a battery, it can deliver a painful shock. Use an insulated screwdriver to short the capacitor leads before disassembly.
• Materials Needed:
  • One disposable camera lens (e.g., from Ilford or Kodak cameras).
  • 3D printed parts from this page
  • Hardware:  Optional M2 screw for the focus stop.

Step 1: Disposable Camera Lens Extraction 

1. Open the camera shell and safely discharge the flash capacitor.
2. Locate the plastic lens held by a retaining ring or screws.
3. Pop the ring or unscrew it to remove the single plastic lens element.

Step 2: Lens Installation

1. Identify the lens sides: one is curved outwards (convex), and the other is slightly curved inwards or flat (concave).
2. Place the lens into the focus ring with the convex (curved) side pointing forward (outward).
3. Thread the lens nut into the focus ring. It should press firmly against the concave/flat side of the lens to hold it in place.

Step 3: Final Assembly

1. Screw the completed focus ring onto the inner ring.
2. Optional Focus Stop: If you have an extra M2 screw, thread it into the side of the focus ring (not touching the inner ring). This creates a "hard stop" at infinity and prevents the ring from accidentally unscrewing.
