gr5: no, the one on the right will not fit the UM3 cores, the UM3 nozzle has a finer pitch thread and not exactly the same length. The one in the picture is made for E3D Volcano / Lulzbot MOARstruder.

We have gotten some requests for a 0.25, but we are not sure either if it really makes sense since 0.25 is too fine for most abrasive materials, and we prefer to only release products that are thoroughly tested and have a real world use.

I agree. I have a few .25mm but haven't sold any. Ruby is good for abrasive materials and those are more likely to clog a .25mm.

So are you working for 3dverkstan now?

Agree with you both there guys, some materials with additives need 0.5mm nozzles, I can't really imagine successfully printing with a 0.25, or even a 0.3mm the likely hood of a collision of partials causing a blockage is greatly increased with the reduced CSA, (perhaps some information on the size and tolerance of the milled grains used for the fill would be handy) particular unless the filament producers are going to increase the fineness of the milling of the partials which will greatly increase the cost, I can't see the market.
I have been running test with a 0.15 nozzle which prints well with good quality PLAs and the like, but at the moment have not got a good quality piece with a 0.1mm nozzle, although I need to test it with Nylon and ABS.
Having sad that, look back at the development in the filaments that has happened over the last 10 years and how 3dprinting has developed, who knows what may be around the corner for the next year.

@@gr5 i do work for 3DVerkstan part-time since a while ago, with a focus on the Olsson Ruby nozzles and other product developments. I still run my engineering company Cederb AB the rest of the time :-)
