Large Delta With CNC Modular Frame

thingiverse

This is a design for a delta printer I created back in 2015, when I still had access to Solidworks. I machined the upper and lower box components and keys on a friend's CNC table from flooring boards and similar easy-to-cut pressed fiber/particle boards. By dividing the frame into sections, I managed to limit the number of distinct frame element types to just four. These elements are keyed together and overlap in such a way that the frame becomes extremely stable. This implementation uses solid 12mm shafts that are 1m long each. The shafts are spaced 80mm apart from each other. The build volume should easily exceed 420mm in diameter and 500mm high. I use 8mm hollow carbon rods, each measuring 500mm in length. I apologize for the lack of backup information at this time, as most parts are still untested and will likely need to be replaced. I may upload the Solidworks files online through onShape because adjusting the slot width based on the type of wood used can be a laborious process and less accurate otherwise (but it's probably possible to modify the DXF cut patterns). Please feel free to remix or send me any files that you think would add value to this project.
