All the models I found on the website had an incorrect design, which could cause finger injuries.
I have created a "correct" design that ensures safe and intended use.
I tested it by hitting the concrete with force about 10 times.
The design may not be visually appealing, but it is primarily designed to be functional.
The teardrop-shaped holes make it easier to put on, provide a more "secure" grip, and make it easier to access injured fingers if something goes wrong. The holes have different diameters due to the anatomical structure of the hand, as the fingers also have different sizes.
The inner edges have rounded corners to avoid post-processing, while the "working" edge has no rounded corners and remains sharp.
The design is optimized for fast printing, and I have tested it at speeds up to 300 mm/m.
Please forgive any grammatical errors, as I am not fluent in English and rely on Google Translate.
