Original author is Francisco. I just remixed it for usage with longer bits.

The 3D model is a bit holder designed for the Einhell TC-CD 18/35 cordless drill, accommodating six bits. This model provides a convenient storage solution for bits directly on the drill. Designed for the specified cordless drill, it facilitates easy handling and quick access to various bits during work. The bit retention force is dependent on how far you push in the bit.
