Door Closer

Need your interior door to close gently on its own? This simple 3D-printed solution uses two parts, a rubber band, and double-sided tape to automatically return doors to a closed position. Perfect for maintaining privacy or keeping conditioned air in a room.

Key Features:
✔ Soft-close function – Gently returns door without slamming
✔ No-tools installation – Uses strong double-sided tape (clean surface first!)
✔ Adjustable tension – Change rubber bands to control closing force
✔ Ideal when:

You need a quick fix for doors that stay open

Don't have a commercial door closer available

Want to keep AC/heat in a room (home, office)

Important:
- For standard interior doors only (not tested on heavy/metal doors)
- Provides gentle closing force (won't fully latch heavy doors)

Great for bedrooms, or closets where you want doors to stay closed but don't need positive latching. Print, install in minutes, and enjoy automatic door closing!
