Encoder for metal Shruthi case?

Hi,

I’ve put one of my Shruthis in Adrian’s beautiful white metal case. However it turns out that the encoder shaft is too short. Can someone tell me what shaft length I need?

Regards

Thank you! Is this the encoder for Ambika as well?

This part will work for Ambika too.

Note that I use a part from another source in the kits - but it’s custom made and sold only in large batches.
