New printhead / toolhead I'm working on — what do you think?
Hello folks,
I would like to show you a new toolhead I am currently working on.
Why? I built a Voron Stealthchanger and tested four different toolheads to see which one would work best. I posted about it earlier, some of you might remember it. After some testing I preferred the Dragonburner and the A4T, but neither of them fully satisfied me, so I decided to try designing my own.
As you can see from the pictures, it is heavily inspired by the Dragonburner design and includes features from the A4T, so credit to both of them.
In the end I managed to make it smaller than the Dragonburner while still fitting a UHF hotend, in my case the Dropeffect Next G Fiber. Cooling performance seems comparable to the Dragonburner and A4T.

I already designed a lot around it. A compact dock that uses as little space as possible and an adapter to align the toolhead to the same height and depth for use with other DraftShift docks, both meant to be screwed onto a 2020 profile. A Stealthchanger backplate and an MGN12H carriage with x-endstop and klicky mount for non toolchanger setups. Several cowls supporting the Dropeffect Next G Fiber UHF. The Phaetus Dragon UHF is said to have the same dimensions and should also work, although I have not tested it. Orbiter, Sherpa, LGX extruders or a simple ECAS mount for Bowden use is supported too. And because of space constraints, I added another EBB36 mount that shifts the CAN PCB up by a few millimeters and provides room for the OptoTap PCB.
When I find more time I plan to upload everything to GitHub to share it with everyone.
For now I just want to show it to you, get some first impressions and maybe some feedback. I also need a bit of help. I would love to see results from an airflow simulation to check how the toolhead ducts are performing, but I don’t have access to such simulations, maybe someone can lend me a hand?
And finally I still need a fitting name for this toolhead. I have not come up with a good one yet. Any suggestions?
