Work in progress - I’m building all the @Printr_bot #FrankenBot parts in Tinkercad. Rods, bearings, threaded rods, couplers, acme nuts and small steppers are done so far.
I think I have all the major pieces built. And some even “connected” (threaded rod, nut, coupler and stepper). The circuit board is just a box and the extruder assembly still needs a bunch of work - but it should be functional.
