Drill Guides (scalable)

To create precise straight holes, simply scale down or up the .stl model uniformly and adjust the hole diameter accordingly. I've added several standard drill diameters to this guide for reference. To ensure accuracy, add approximately 0.2-0.3mm to your desired diameter based on your print settings. Note that the specified diameter in .stl files already accounts for an additional 0.2mm.
