We have a number of Wanhao i3 Duplicators (Essentially a Prusa i3) 3d printers here at the Hutt city Libraries. They are the core of what will hopefully be a Makerspace embedded in the library. Rather than have them just sitting there I was keen to find a project that would challenge them, and take a while to print. Searching around Thingiverse led me to lalbritton’s fantastically ornate Ideal Harmonic Transformer (and Annotated version). This fit the bill nicely.
The build volume was a bit smaller than lalbritton’s design allowed for and so I separated the components and we printed them one at a time. I also designed in a break in the yoke arms so they would fit on the bed. Because I was not keen to use the printed pins and screws lalbritton had so carefully designed, I took the liberty of drilling out the holes to take M4 or M5 machine screws. To ensure maximum strength and flatness I also blobbed a bit of epoxy glue into most joins.
So it works, and looks fantastic. Thanks lalbritton for designing such a cool looking device.
Original STLS were all re-edited in Blender to separate the components out. The yokes were edited to introduce a split so they could be printed on a 200mm x 200mm bed.
