The supplier was a great communicator and service was good. The quality of the prints however were not as good as I hoped, however supplier printed again.
Response: Hello Matthew,
We aim to please. Thanks for yor custom
Took just over a week to complete the order so pretty speedy. The item allows me to grind coffee directly into the portafilter, which is great. It's slightly less sturdy than I was expecting but performs its function perfectly.

Came out as expected, it was for a small project so top quality wasn't a priority nor to be expected as it's just a 3D print at the end of the day and for impecable quality from any 3D print you would be expected to pay mega money for the material and the overall printer quality.
But overall for the price I am more than happy with the outcome, the seller was quick as shipping and arrived safe and sound. I wouldn't hesitate to use the same seller again in the future for any further project needs.
Response: Hello, glad you appreciate our services.
Many Thanks !
