My Dyson brush had a catastrophic failure…
There is no official distribution for Dyson replacement parts, so I had to work around it. The whole brush is over $100, the turning connector can be found at around $35, so why not have it for free?
Recommended at least PETG with strength settings like 6 walls and/or 80% infill. My first prototype in PLA - draft quality - lasted for around 6 months because I was too lazy to disassemble it again. This version is revised and should last longer also due to adjustments of some stress points.
Now the replacement process is quite time consuming but if you buy the connector at $35 you'd need to go through it anyway.
