Balance wheel with holes for grub screws (speed tuning)

For proper fine-tuning of the ticking speed for my clock, I radially drilled 4 holes into the balance wheel and inserted grub screws. Turning the screws closer to the axis center makes the clock tick faster.

In this remix, I've added the holes directly into the 3d-model, and accurate drilling becomes much easier or maybe even unnecessary. However, for an accurate clock speed you still need to play with the infill density until the clock runs slightly too fast (10%) without screws. Then you can insert M3 grub-screws (pair-wise) until the speed is OK ...

I didn't check, if this remix prints properly, and would be grateful for a short comment, how your printing worked.
