In an effort to get everything to as native a voltage as possible, I planned to swap out the fans on the extruder to run at 24 volts, and therefor simplify my life. Well, that's exactly what I did.

Here is where I started, the extruder is already heavily modified. The original small squirrel cage blower style fan on the head break has been replaced by the larger Noctura fan in classic brown. The part cooler fan ducting has been replaced with split ducting. The extruder has been fitted with 1.75mm PTFE tubing and a different clamping arm to facilitate printing in 1.75mm filament.

I switched to 1.75mm filament because so many of the lower cost 3D Printers use it, which makes it in demand. Because it is in demand, there are lots of manufacturers creating interesting filaments, and there are filament sales on 1.75 more often then I see for 3mm. That means that the extruder design here is WAY overkill as it is designed to move and heat 3mm filament, but so far, the performance has been good with 1.75mm.

You can also see the test fit of the mount for a BL Touch that I printed in resin on my Elegoo Mars 2P. It's not strange to have more than one 3d printer. Totally normal.

Here we are all assembled. Not much to show but a bit of a color change, the BL Touch in place and some heat shrink for the eagle eyed among you. I'll do a little wire management with some black zip ties, and we should be good to go!
