Coin Holder

Coin Holder
I use these to save holes in my trouser pockets, but the leather versions only last a couple of months so I came up with this design.

Printing:
1. Print as two seperate prints with the case at 20% infill and the lid at 100% infill (purely to stop the catch snapping off!)

2. In the slicer, rotate the lid 180 degrees about the x-axis so it lays flat

Post Print:
1. The hinge pins are a very good fit in their holes so it's a good idea to insert them from the outside and give them a few turns to bed them in before assembly.

2. I have purposely left the catch tag too long so it can be filed to give a good fit/operation. When it's still too long, the lid won't open by hand. Slide a blunt knife under the lid at the front and twist to easily open until the tag is the correct length.

3. A thin layer of self-adhesive felt should be stuck onto the inside of the case and lid to prevent the user (and others) being driven insane by the rattling!!
