35mm to 120 Film Adapter | 3D Printed

Transform your 35mm film into medium-format experiments. This 3D-printed adapter lets you re-spool or mount 35mm film so it can be used in cameras or backs that accept 120 spools — ideal for creative play, testing, and hybrid analogue workflows.

Colour: Based on availability (Assorted)

What it does

• Lets you use 35mm film in cameras/holders that take 120 spools (re-spooled or unboxed).

• Secure, low-profile fit that holds your 35mm roll steady while you shoot.

• Great for trying different aspect ratios or making test rolls

Key features

• Made from premium PETG — tough, temperature-resistant, and long-lasting.

• Precision print for snug, wobble-free spool engagement.

• Lightweight and compact — easy to carry in your kit.

• Smooth openings for easy re-spooling (recommended to re-spool in a dark bag or changing bag).

Compatible with

• Most 120 spool-style medium-format cameras and backs that accept standard 120 spindles.

• Works with boxed or unboxed 35mm rolls once re-spooled onto the adapter.

What you need to know before buying

• Does not include film — adapter only.

• For best results, re-spool in complete darkness (changing bag/darkroom) to avoid fogging.

• Some proprietary medium-format backs may have different spool tolerances — check fitment if your camera has a unique spool design.

• We recommend testing one roll first to confirm frame spacing and advance behavior on your camera.

Care & handling

• Wipe with a soft, dry cloth; mild soap and water if needed.

• Avoid prolonged exposure to very high temperatures.

What’s included

• One 3D-printed 35mm → 120 adapter (single) — option to buy paired adapters available on the product page.
