One of the more fun aspects of owning an open source 3D printer is how easy it is to customize it and make it your own. You may have recently seen the
special edition printer we released to commemorate our 10th anniversary and that we donated to the Sanjay Foundation to be auctioned off. While we won't be going that over the top this week, our theme is a pretty simple printer modification that can be an easy way to add some personality or better ergonomics to your printer, the LCD knob. While we don't expect all of you to have one of our printers, all valid entries must be for a knob that goes on either a 3D printer or fits the same rotary encoder found on the standard RepRap LCD control panels.
