Rostock Plywood Eliminator

thingiverse

Designing a replacement for the plywood on the Rostock requires creating a frame out of 5/16" threaded rod, which will connect the top and bottom of a Delta Printer in a triangle-like configuration. I created this mostly as an experiment in hardware sourcing but it also has potential to be used for making Rostocks more expandable. 10/13/14 Update: Upon printing and assembling the part I found that captured nuts do not function as I intended. To effectively use these parts you need to tighten both sides just like my Prusa i2, which means you should adjust them properly. UPDATE 4/22/2015: The Rostock Frame Design project is no longer abandoned due to an unexpected rediscovery and a successful rework of the files. Before building this Rostock design make sure that all screws and motors are in their respective places for easy assembly. Print at a high quality of PLA plastic with a minimum 40% infill rate using 0.2mm layers and use those screw points where motor mounts go. Using Rostock's Idler pulleys ensures correct motor alignment making it much easier to adjust these components before assembly starts so they all end up exactly aligned which results in great precision while building the structure and printing with the Delta style system that utilizes them all together for creating smooth, round products.
