RHD Fan duct for MK3 Bondtech BMG Mosquito
Description
2020-11-26 Uploaded support for MK3 original extruder (RHD_MK3_Mosquito_support.stl). EDIT: Now it works to download the entire file package. There have been major problems with Thingiverse that could not package the files I uploaded. A nice guy (Murky) contacted me and told me that he had upgraded his MK3 with a Bondtech BMG Mosquito extruder. However, he was dissatisfied with the nozzle (ie Fan Duct) that came with the extruder, because it was bad at printing overhangs. Murky wondered if I couldn't fit my C-nozzle to Mosquito extruder. Murky had done his own tests with this and found that the result was much better. The disadvantage of the C-nozzle was that it was not adapted for Mosquito, and parts of the nozzle melted. The result of Murky's tests and my flow simulations resulted in a nozzle that I call M-nozzle (M for Mosquito). I also made a new fan support because Bondtech original support does not fit this nozzle. It would probably have been possible to make an even better nozzle if the heat block had been turned 90 degrees. Then the nozzle could have been placed much closer to the extruder nozzle and it would have been easier to control the air flow there. A big thank you to Murky for helping improve the print quality of Bondtech BMG Mosquito extruders. A tip about printing the M nozzle will not be perfect (poor overhang). Then mount this "bad" nozzle and then print a new one and your overhang will be better. Please use the enclosed gcode, it is suitable for printing with ABS filament. Fits also Zaribo, Bear and all printers with bmg+mosquito.
