However, the model has a significant flaw: the orientation is not good during printing, the wall thickness is too thin and prone to breakage, and it does not have an automatic release function. As a result, the screw head will damage the plastic fixing base when it enters the wood.

Hexagonal head drill bit sizes:

Small size: The minimum size is definitely 35 mm, and it is recommended to choose 45 mm
Large size: Absolutely at least 50 mm, recommended 60 mm

There is no upper limit for the length of the drill bit.
