I’ve put some hours into CAD this week, designing two upgrades to improve my Ender 3 that you can benefit from too.

The first is an adaptor to join my two favourite Ender 3 extruder mods together: the direct drive kit from Basaraba Innovations and the EZR extruder. This simple part gives reliable and convenient filament loading, with improved printing performance.

The second aims to tidy up my electronics, which were accessed underneath the printer and had buck converters and other components loose. I’ve created a modular system for mounting the electronics at the back of the machine, to suit the standard Creality board, an MKS Gen L or an SKR 1.3. There are also mounts for TL smoothers, a raspberry pi, a buck converter and two relays. The cooling fan is now much quieter and can be upgraded to a 40x20mm design without issue.

All parts are easy to print without support and fit on an Ender 3 bed. This should be compatible with the standard Ender 3 and the Ender 3 Pro.

I'm really happy with my design and I hope others can benefit too.

The cable clip I showed in the video came with the direct drive kit, but here is another that will do the same job: https://www.thingiverse.com/thing:294...
