I read an article about weaving with an "inkle loom". I thought it would be fun to do and I decided to 3D print one. 

There were few examples to be found so I drew one myself.

 During the first test it turned out that the pins were too flexible and that's why I made a reinforcement. That worked well. 

The adjustable pin broke off soon and I replaced it with an M8 bolt with wing nut. That worked fine. 

This device suffices for a test.
