Drill storage for toolwall

thingiverse

To organize my tools efficiently, I'm creating a tool wall with drill storage containers as the initial design. Currently, I'm facing an issue in my slicer, which is set to 30% infill. It struggles to produce dots between numbers (like 1.5mm), and I can't seem to identify the reason. If you have any insights on this problem with Cura or the included slicer, your suggestions would be greatly appreciated!
