Balance wheel with holes for grub screws (speed tuning)

thingiverse

To get precise tuning of my clock's ticking speed, I've strategically drilled four holes into the balance wheel, allowing me to install grub screws. By turning these screws inward toward the axis center, the clock begins to tick at an increased rate. In this revamped version, I've incorporated the pre-drilled holes directly into the 3D model itself. As a result, achieving accurate drilling has become much simpler or possibly even redundant. Nevertheless, to attain an exact clock speed, it's still necessary to experiment with infill density until the clock starts running slightly faster than ideal (10% margin without screws). Once you've achieved this mark, you can then install M3 grub screws in pairs until the desired speed is met. Please note that I haven't tested this modified design for printing yet, and would greatly appreciate any feedback on how it actually printed out.
