Center Finder for round stocks

thingiverse

I noticed many designs similar to this one, but they often failed to provide clearance for the writing instrument. In contrast, this particular design allows for a precise 0.3 millimeter offset from its centerline. This is because standard markers typically range between 0.5 and 0.6 millimeters in thickness, while pencils are even wider. As a result, using a marker with this design ensures more accurate centers. Scaling or resizing the model is not recommended, as it would disrupt the carefully calibrated offset and wall thickness. If you require a larger version, I suggest sending me a private message to arrange for an upload of an expanded file. Measuring 56x56 millimeters in size, with a usable inner diameter of 50x50 millimeters, this model is versatile enough to accommodate tubes ranging from 8 to 100 millimeters in diameter.
