UConduit H-Bot 3D Printer / Reprap

The UConduit 3D printer is an h-bot 3D printer, with a frame built from electrical conduit (steel conduit that you can find at the hardware store). The source files are hosted on github at https://github.com/iquizzle/uconduit. All printed parts are designed using OpenSCAD so that parts can be freely compiled and modified. Conduit was chosen as a frame material for its low cost ($3.50/5ft), stiffness and hardware store availability. Standard build volume is approx 250mm in each dimension.

The printer is held together using o-rings and compression flanges. Each end has two rubber o-rings. There is a *hard clamp* and a *soft clamp*. The hard clamped o-ring creates a pivot point and firmly holds the conduit in place. By adding a second *soft clamped* o-ring on each end, vibrations are very effectively damped. As a result, the printer is not only fast, but also super quiet! Additionally, wiring can be neatly routed from the top to the bottom of the printer (using the conduit for its int
