Portafilter Dosing Kits for DF Series Grinders

This addition to the grinder works great. It holds portafilter perfectly. Why didn’t the original work?
Does anyone do design reviews before releasing.
The original fails unless you hold it in place.

The accessory I've been waiting for all my life.

This is a handy accessory to have, is built quite sturdily and works as intended. It does not look like it's 3D printed as it has smooth sides (only the bottom side has the ridges). I can't attest to how it works with the required funnel as i am using another brand's funnel and had to carefully shave some of the plastic, but it does work great. You will need a hex wrench to install it, not sure what size though.Edit: I also wanted to add that because it puts the grounds so close to the exit chute that you have to be careful with the bellows because if you blip it too hard it can make a mess , so either use RDT or a gentle tap
