The first image shows the Eddy probe pressed down. The second is an estimate of the nozzle/shroud height.

Yeah, an extra few mm of room for the Eddy to move up would be nice. I am making progress on the shroud but I'm not sure how quick it'll be finished. 

I will also try to hack together a modified core to fix the 3mm difference.

I imagine that must be a huge job. As you suggested, I might try a slightly longer shroud.

That's really kind of you!

I think you use Blender for adjusting the parts? I could check with my brother, who's quite knowledgeable about this, if I need to make any other adjustments in the future.

However, when I took my measurements, even though I changed the heating block, I got the same measurement as the TCHC-TD6S. It was really my desire to hide the Eddy probe in place of the Omron probe that led me to intentionally lower the hotend and, consequently, use a shorter shroud for cooling.

I think the root of the problem is the carriage, which doesn't leave enough room for the Eddy probe. I have another SwitchWire/Eddy USB/Orbiter 2.0 kit, but this time with a Bambulab hotend. It doesn't make sense to change all the cores, and I don't want to leave the probe exposed.

I'm going to try removing the Eddy probe's housing to see if I can gain the missing millimeters in the setup. However, I'm worried that the PCB might lack thermal protection.

I have seen people running the Eddy without the housing but it doesn't look like it makes it any shorter.

Here is a shroud that is stretched by 3mm. The geometry isn't perfect but I checked it in the slicer and it looks clean enough. This is for the 2510 hotend fan but it is very easy to modify the mesh for a 3010 fan. I will work on the core tomorrow.

2510 is my setup! Il will try it for sure Thx a lot!

@HolyFrank Here is the stretched core for the TCHC-TD6S. I just shifted the bottom face down by 3mm. It should fit M2.5x8 screws for attaching the hotend.

Finally, I apologize, but I'm using a 3010 fan... Do you have the source files if I need to make changes using Blender? I don't want to bother you about it! You've already done quite a lot!

No worries, the 2510 shrouds just include an extra body so it is easier for me to manage all the different versions. The 3010 shroud is attached.

The Blender file is pretty much the exact same mesh as the .stl files. The learning curve in Blender is a bit steep but once you get comfortable with it you can customize any .stl file out there!

If you want to give it a try with the 2510 shroud, you could import it into Blender. You might have to Frame Selected by hitting the numpad [.]. Then the first thing to do would be to select the body and hit [Tab] to go into Edit Mode. It should go into vertex mode. Next, select any vertex of the green part shown above. Type [Ctrl]+[L] to select everything that is linked. Then just hit the [Delete] key and choose Vertices. Now you can [Tab] back out of Edit Mode and export a new .stl file.

Would this extruder just require the orbiter 2.5 upgrade kit as far as internal parts?

The WristWatch Orbiter 2.x extruder is finished! Unfortunately the 2.5 upgrade kit is missing the 4x16mm shaft for the idler arm as well as the tensioning screw/spring. The 4mm shaft can be replaced with an M4x18 screw but the tensioning screw will have to be sourced seperately.

This extruder also has the filament cutter option that I developed for the WristWatch BMG extruder.

I saw you added support for the K1 Extruder. Any chance you will also add K1C and K2 hotend compatibility in the near future?

I have just pushed a full set of Creality K1 hotend core pieces to GitHub. They are separated into the applicable extruder folders. The K1 hotend will fit into the UHF shrouds. It uses a pair of M3x8 screws and M3 square nuts to attach the hotend to the core.

Thanks! Looking forward to trying it out. Any recommendations on a extruder to pair well with the uhf shroud? Looked at your configurator but I'm sure you haven't had a chance to update it with all the recent changes as well as the new wristwatch extruder being made.

Yeah, I never finished the configurator. All of the layers of if/then logic got too complicated for my rudimentary JavaScript knowledge. 

Each of the extruders has a full set of shrouds available with either 3010 or 2510 hotend fans.

I prefer to have a filament release lever so I've made modified versions of these four extruders.

I would like to add a release lever to the WristWatch extruders but I'm still working on ideas of how they might be able to fit.

I know of one remix of the protoxtruder 2.0 that has a release lever arm. I was planning on remixing that to work with the stealthprotoxtruder 2.0. Im assuming the protoxtruder 1.0 and 2.0 are interchangeable with the mini stealth.  https://www.printables.com/model/1026015-protoxtruder-20-long-idler

The stepper motor sits very low on the ProtoXtruder 2.0 so you might need to use a spacer so that the stepper clears the printer's x-carriage.

Since you have already released a K1 extruder version. Has anyone tested to see if the drop in DXC extruder fits? Looks like a very capable pre built extruder with two griping wheels and two idler wheels. I've seen some pretty impressive tests with it pulling 6kg weights and feeding 85a flexibles. This is the only mock-up I've come across. Looks like it sits a little taller than the stock k1 extruder. https://www.printables.com/model/1339561-dxc-extruder-mock-up

The DXC extruder looks like it should fit onto the K1 adapter I designed for the Mini Stealth but it is about 16mm taller. It would probably work fine with a crop-top shroud, just maybe not so well in a V0.2 printer..

The front corners of the extruder foul a little on the adapter but that would be easy to file or trim away.

Status update. Just need to tidy up the wires, glue in the fan guides and likely make a custom little internal fan shroud for the 3010 for the K1 heatsink. So far SV06 Mini SB is going well. I ended up temporarily giving up on the toolhead mounted filament sensor idea for now. The space between the gears of the stealthprotoxtruder 2.0 and the K1C unicorn nozzle is only 12mm and I plan on printing a decent amount of tpu so simpler is better.

Is there any chance i could get you to make a version for the e3d revo micro? i have one laying around and am gonna rebuild an ender 5 pro laying around... and this is perfect for it, but i suck at cad :D lololol

I will take a look and see if it could fit.

I have pushed new core pieces (standard and rigid) to GitHub for each of the extruder setups! They fit the standard shrouds.

The geometry is "borrowed" from Rein3003.

Yay you rock thank you!
