Rotating Pen Holder

thingiverse

Rotating Pen Holder that can hold up to five pens at a time. To build it, you'll need a bearing with an inner diameter of 10 millimeters, an outer diameter of 30 millimeters and a width of 4 millimeters - these components are readily available in any construction store or online marketplace. When printing this design, I used a resolution of 0.1 millimeter, but 0.2 millimeter should also work well. However, I would not advise going lower than that since the ball bearing needs to be pressed into place within the bushing part. As for supports, none are required during the printing process.
