Designed with the intention of being printed in steel, all initial tests were done in PETG.
The primary reason is to use the CHT bimetal hardened steel nozzles from Juupine, that go into their Bambu Labs Clone.
The thermistor and heater are the same, and can be swapped over from the Sovol to the Bambu hotend.
I have achieved a reliable 42mm3/s of PLA with above nozzle, compared to 27mm3/s from the Sovol Hotend.
You MUST do a PID tune, and while all intentions was for the nozzle to be exactly the same height, you also must do Z height.
I found in PETG it was about 0.2mm closer to the bed, but in stainless steel it was 0.02mm higher. The second was within mounting error.. but these are the exact same STL, so be aware, you must calibrate.
The reason for steel, is my intention is to heat the enclsure to 60 C or more, and as can be seen with the thermal camera, that would see the mounting point that is about 30C above ambient, see about 90C.
Also bambus design suffers heat creep, the heatbreak they have sucks, and causes blockages a lot, especially in their own printers. This is to try and eliminate that risk. So far I have tried to block it (PLA, heated the hotend to 250C, waited 5 min, took the thermal pic, cooled it down, then heated to 190 and tried to extrude, with success).
2 Versions
Both are designed to be tapped. .. be warned, stainless was horrible to tap, but it worked.
With plastic, the thread should self tap.
Fusion File includes SOVOL Extruder - with increased tolerances
STEP file is also with increased tolerances.
Fins are sized to suit JLC3DP guidelines for SLS Stainless
Designed for these, initial tesing was done with official bambu hotends, fully compatible with both.
