Curtain / blind pull chord hook. Prints in 4 pieces for maximum strength - stress on a given part always runs with layer grain instead of against. It might seem overly complicated, but I wanted to show that some creative part orientation and fine FDM printing could go a long way to making even a small item quite rugged. 

Most of the key dimensions are identical to the original but I took a few liberties with dimensions to add strength where needed. I'm not sure how widely used the original is, I got this request from Sweden, but I think the hooks are still available.

Print

Print in PLA (or stronger) at the default orientation for each part. Try to keep layers as thin as possible - example prints are 0.15mm on a stock Prusa MK3 0.4mm nozzle. Nothing fancy, just some extra print time.

Supports not necessary, even for Arm with its projection.

Assembly

Use the assembly guide image if necessary.

1. ARM slides into slot in BASE.

2. END then fits onto ARM (use the large hole on END),

3. WEDGE  then fits into other hole on END. Note that WEDGE has a small indexing notch, notch should face away from BASE. A small amount of glue in the END hole is advisable, but not strictly necessary - a pressure fit might be fine for your needs. Glue is mostly to prevent the part from slowly working its way out.
