- A brown paper grocery bag/lunch bag for your hinge.
- Sharp Xacto knife
- White glue
- Sharps cartridge box label
- Ruler
- That's it!
- Cut one long side off of the lid. Removing the bulk off the back of lid helps the box slide in and out of the tin much easier. Cut carefully and don't try to cut all the way through at once. Multiple passes make for a cleaner cut. Then put the lid back on and check the fit. You want the lid to fit flush against the back.
- Using a large Popsicle stick, like I do, or using a ruler, cut a roughly 3/4" strip off of your grocery bag. If you're making several, cut a long piece.
- Butt one end of your strip up against the inside of the back of the lid and using your Xacto knife cut the hinge to length on the inside of the other side of the lid. You're going for an inside diameter fit.
- Fold your hinge length-wise taking care to make a very crisp fold.
- Using white glue (or glue stick, or other gluing method) use just enough to evenly coat the inside of the hinge. Spread evenly with your finger. You don't want any puddles or squeeze out.
- Put your lid on the your box and apply the hinge. Aligning it carefully, smooth the hinge to remove any air bubbles that may have snuck in.
- Let dry.
- Apply Sharps cartridge label and enjoy!
