Box FIXATOR – Cardboard Box Corner Clips

Simple reusable corner clips designed to reinforce cardboard boxes and keep the walls aligned without glue or tape.

I made these to quickly strengthen storage boxes and give reused cardboard boxes a cleaner and more solid structure.

Perfect for:

• Storage boxes
• Workshop organization
• Shipping and moving
• DIY cardboard projects
• Temporary containers

Features

• Fast snap-on installation
• Reusable design
• Improves box rigidity
• Clean minimal look
• No supports required
• Very fast print

Print Settings

• Recommended: 2 walls/perimeters
• Recommended: 100% infill
• PLA or PETG recommended

A full set of 4 clips uses only ~15.5g of filament and prints in about 40 minutes on most printers.

Notes

Designed for standard corrugated cardboard thickness.
Easy to scale if needed for thicker or thinner cardboard.

Happy printing!
