After about ten nice and fruitful exchanges with SebCreation this tiny object with precise dimensions finally came to life. The result is very good. We are very pleased.
Awesome job with the prints. I did end up slightly modifying things to make it fit with my project, as the prints didn't account for the 18650 battery holder I ended up actually getting.
I am very satisfied. Print quality is very good and manufacturer presented great attention to detail and extreme engagement. Would recommend to anyone.
