I figured I would mock Apple's naming scheme a bit. Next version will be the Sprite Pro Plus Max

This is a heavily modified sprite pro. I wanted speed and good cooling, without buying an entirely new toolhead. At this point I may as well have though, but whatever.

This toolhead is designed for an Ender 3 v3 heatsink, BIQU Microprobe, and a Triangle Labs CHCB-OT hotend. This toolhead will likely NOT work with any other hardware.

I printed this with ABS. Could probably work with PETG though I dont suggest it. 

Thus far, I have reached print speeds of 700mm per second, and acceleration of 50k mm per second. 
My speed is not capped by the toolhead itself, but by the fact that I have not anchored my printer to the table properly. 

In order to mount the heatsink fan as I did, you will need m1.5 bolts, and to put threaded inserts in it:

You could use longer bolts and nuts on the other side, but that is too much work in my opinion.

To mount the bottom half to the extruder motor, you will need two M2.5x10 bolts.

You can also see how things are mounted inside with this picture. I myself used the Microswiss ender 3 v3 heatsink, but the stock ender 3 v3 heatsink works well too. As you can see below , in order to mount the microswiss heatsink I had to grind the top two corners so it fits with the screws. 
(Note: The standard ender 3v3 heatsink does NOT need grinding, only the microswiss)

Dont forget your PTFE tube
