About this 3D model

Just a simple reprap knob for an LCD. The other ones I found on here had a notch - the noname LCD I procured from ebay did not. Simple knob. In the photos above the new knob is on the right. The 3 on the left are prints with the notch manually cut out. Where they got better as I overhauled my robo3d. Sorry some of the fotos are ugly.
