E61 Espresso distribution tool

E61 espresso distribution tool, inspired by https://www.thingiverse.com/thing:3478313 and build for the E61 portafilter.

It locks into the E61, using the portafilter notches and you can rotate the top part to evenly distribute coffee. It really works !
I attached a picture of coffee before and after applying the distribution tool

Needles:
- I used 0.43mm guitar strings (the G string form an electric guitar). You can customize the diameter.
- I cut 28mm sections in length. This was just touching my 24mm basket, adjust based on your basket height.
- Bend 1mm to support the between the gear and the needle holder (see pictures).

v2:
- the needle holders have a tighter fit, to avoid the need of glue.


The openScad code is included so you can customize it for your portafilter. I used this one to make my edits: https://www.thingiverse.com/thing:53451
