The ender 3 is a cheap, open-source 3d printer that is ideal to tinker with and modify.

Recently I've been trying to get the best quality possible out of it, and so decided to switch to a direct drive. You can read more about it here.



I wanted to spend the least amount possible - hence, buying a direct extruder such as the titan or a bmg was out of the question.

I decided to use the original extruder. Some might argue that it adds too much weight, but I think the glass bed will be more impactful on maximum printing speed. Also, the results I've read from other people doing it have all been great.

In parallel, I also wanted to upgrade my cooling system. I already had a petsfang, which is incompatible with the direct dive mod I chose, and being obsessed with silence I figured two blowers instead of one would enable better performance with less noise.

The whole system needed to be compatible with my BLTouch.

Make sure to print all required parts before starting the build, as otherwise you will be unable to print.

You will need to print these:
