      Current Status: Working out a couple kinks on the endstops

      1. Develop proper body parts to hold the corners, currently using 90 degree brackets.
      2. Expand the printer, currently not utilizing all of the default print bed.
      3. Possibly add an extrusion (currently using the AirTripper)

      Summary: Pretty simple design, this uses the mini gantry from openbuilds and belt drives for the X-axis. The Y axis contains the mounting brackets to attach this so we'll get to that later.
      Bill of Materials:
      1. Assemble the mini v gantry following the openbuilds spec and slide it first into the center of the extrusion.
      2. Use 2 square T-nuts on either end for the motor and wheel brackets.
      3. Attach both ends so that the wheel and gear are about 5mm from the extrusion, we'll tighten it later.
      4. Run the belt so that the underside is inside of the extrusion slot, and the top is running above the top of the extrusion, the wheel and gear should naturally put it in this position.
      5. Wrap the belt through the slots of the mini gantry, then use some zip ties to fasten them down. I prefer to use two zip ties on each end so it doesn't slip. This should be snug but don't worry about tightness.
      6. After the belt is looped through the gear, wheel, and is attached to the gantry, loosen the wheel end bracket and push it out to tighten the belt, then re-tighten the bracket.
      7. Use the 4 low profile 10mm screws to fasten the hot end mount to the top of the gantry plate.

      Began in July 2017, CAD done using Autodesk Fusion 360. Going to upload the STLs here and the list of build materials. Tried to source everything I can through openbuilds for consistency, a few self printed parts and remnants from the Mendelmax used where applicable.

      This build began back from the Mendelmax 1.5 printer I had been using for a couple years now. Moving the entire print bed for the Y-axis was so much mass that it caused vibrations in my prints, which spurred me to trying to CAD my own cartesian printer.

      Additionally, I had already started slowly replacing the smooth rods commonly used on the Mendel design for the X/Y Axes into Openbuilds extrusion, and found quicker/lighter movement, and a lower noise volume compared to the linear bearings rattling (I live in a studio).

      Not doing any fancy core-xy here (maybe convert this in the future to it, not sure), but have found this to so far resolve my problems.

      The extrusion cuts may not be ideal for most, was trying to reuse all of the extrusions I had from the Mendelmax and a few leftover from another side project, so feel free to tweak those numbers.

    Reason for this Build

    I kept trying to cut weight on the bed for the Mendelmax design so I could run it faster, and eventually gave up for this gantry-style which I find to be a much lighter operation. I feel the stationary bed improves layer adhesion.

    Ubermeisters inspired me a lot to build this, he mentored me for a long time and I always wanted to rise to his level.
