Summary I got tired of the bowden extruder on my Tronxy X3S. After recently buying an original prusa i3 mk2s and falling in love with it, I decided I wanted to add a the prusa style hotend/extruder assembly to my tronxy. I stumbled upon 3DPropWorx's remix of the prusa i3 mk2 extruder and thought it was perfect for what I wanted to do. Plus I figured I could get away with not having to purchase anything to do the conversion as I already had an e3d v6. So besides that, I just needed to modify it to fit to the tronxy and to accept some of the tronxy parts such as the extruder gear and idler. It's designed to bolt to the original tronxy x carriage plate from the back side using M3x8mm screws through the holes where the original hot end stand offs go (you'll have to drill holes for this, however, I may add these holes to the model in the future). You will also need to fully assemble this before you mount it to the x carriage plate. I didn't take note of the number or size of screws and bolts used, but I can probably go back to catalog that information if there is a demand for it. For the most part you end up using the screws/nuts from the original prusa assembly guide. Just be sure to measure lengths.
