This is a self-sourced I3 MK3 Clone. It currently is a near-exact replica of an I3 MK3 Haribo, with the following deficiencies:
No Power Panic
The filament sensor is a standard IR optical sensor, not the PRUSA laser sensor.
It is likely that these parts will be cloned at some point (the power panic board could easily be cloned, but the sensors Prusa uses for the filament sensor are hard to come by.)
It runs a (slightly) modified PrusaFirmware 3.2.1 (for modified axis length, filament sensor). It passes X/Y/Z calibration, and everything works perfectly! The Haribo frame is also incredibly solid, especially with the power supply and Einsy case rigidly attached to the extrusions. It has been printing very reliably for the last month. I have filament runout detection working, although it can be a little sensitive to ambient light changes.
Honestly, if I did it again I would either just buy the MK3 or buy the MK2S->MK3 upgrade kit and add the haribo frame. This really isn't much cheaper. But it's very solid, prints…
