Reinforced cleat with through holes

Dissatisfied with the weakness inherent in the long thing bits on most cleats I made this cleat that is mounted by angled screws that travel through the arms of the cleat horn thingy.
This way the printed part is reinforced by the metal screws that mount it.

This one is designed for 4mm screws 38mm long. But it will probably work with and screw 3-6mm diameter and 38-50mm long
