Bushing
thingiverse
While constructing my Makerbot, I discovered that there are several unprinted plastic bushings. To make use of these, I created a printable version for them. Although there might be valid reasons not to use printed versions currently, I couldn't find a suitable bushing design on Thingiverse. The OpenSCAD file is used to create this bushing and allows measurements by either radius or diameter. So, just print, use, and enjoy!
