friction fit curtain hooks

My curtain originally hanged on a flimsy thread which broke in several places. This made the curtains hang again.

The hook is made up of 2 parts: hook and key. You'd put the hook under the fabric and the key over the fabric. Then slide the key with the fabric into the hook body from the top - this might be a bit tricky depending on thickness of the fabric. When the fabric is thin enough you may get away with snapping it in. My curtain are roughly 1.2-1.6mm depending on where I measured. The default key has 0.5mm clearance with hook body, it may seem very loose but with the fabric it holds really well.

Printing stuff

• I printed them with 0.28mm layer heigh, but that probably doesn't matter much
• I used 5 perimeters for strength on hooks and 100% infill
• the key doesn't need to be that strong, so I printed the keys with 2 perimeters and 20% infill
