UConduit H-Bot 3D Printer / Reprap

thingiverse

The UConduit 3D printer is an h-bot model, built with electrical conduit as its frame. The source files can be found on GitHub at https://github.com/iquizzle/uconduit. The printed parts are designed using OpenSCAD to allow for easy modification. Electrical conduit was chosen due to its low cost, stiffness, and availability at hardware stores. Standard build volume is approximately 250mm in each dimension. The printer is held together using o-rings and compression flanges, with hard clamps creating pivot points and soft clamps effectively dampening vibrations for a quiet operation. Wiring can be neatly routed within the conduit. The design has undergone multiple revisions since September, with continuous support and upgrades planned until it reaches the hacker community. A Google group for discussions and support is available at https://groups.google.com/forum/?fromgroups#!forum/h-bot-and-corexy-3d-printers. To build the UConduit, download the BOM and STL files from GitHub. Print necessary parts, assemble the frame using o-rings and compression flanges, install linear rods, assemble x-ends, y-rods, and carriage, mount the J-head, install stepper motors, assemble z-ends with leadscrew couplers, and wrap the GT2 belt. Detailed build instructions will be available soon. If assistance is needed during assembly, join the Google group for help. A ball end hex key is highly recommended for easier assembly. Don't forget, UConduit is also endorsed by Rob Schneider! Check out the video at http://www.youtube.com/watch?v=73MlaBWCTPU for a demonstration.
