š© Assembly Instructions
Hinge System
The hinges are reinforced using:
- 2.4 mm stainless steel welding wire
Cut the wire to the required length and press-fit into the hinge channels.
ā Important:
The hinge holes in the lid must be drilled to 2.5 mm to allow smooth rotation.
Do not drill the base hinge holes ā they are designed for a tight press fit.
This ensures:
- Secure pin retention
- Smooth lid movement
- Long-term mechanical durability
Gasket Installation
The TPU 85A gasket is printed separately and inserted into the dedicated groove. It may be glued in place with super glue.
The lid compresses the gasket when closed, creating a reliable waterproof seal.
The compression system ensures proper sealing without excessive latch force.
š Ideal For
- Camping gear
- Electronics protection
- Tools & spare parts
- Survival kits
- Travel storage
- Field equipment
ā Tested & Proven
This design has been printed in multiple material combinations and tested for:
- Fit accuracy
- Seal compression
- Mechanical hinge durability
- Long-term latch performance
The steel pin hinge system significantly increases lifespan compared to fully printed hinges.
