For those looking to add a mosquito hotend and lgx extruder to their Prusa Mini Bear I have collected the mirrored parts for you here. Also providing insight from my experience working through the upgrade.
Print Settings:
Material - PETG [improved heat resistance, Nylon would be even better]
Nozzle Size - 0.4mm
Infill - 15%
Supports - Not needed
Hardware:
M3 Fasteners -
I don't have the exact counts of the lengths used and needed but getting an M3 bolt pack will come in handy for the build. I used some I didn't have from the previous extruder assembly I tore apart. Link - Amazon
Heat Set Inserts -
The printed parts do require heat set inserts to be installed with a soldering iron to assemble. Link - Amazon
Extruder Power Cord -
Link - Bondtech
Build:
Once your printed parts are complete use soldering iron to install plastic inserts. The following parts will need inserts -
Base [7x]
Cover [2x]
X Carriage [2x]
Once complete take a look at the video below for building. Keep in mind everything is mirrored.
Assembly Video Instructions -
Once everything is assembled there are a few settings you need to change in both the slicer and the printer itself.
- Retraction speed: 35 mm/s
- Retraction distance (direct drive) for rigid materials: 0.4 mm
- Set extruder steps to 400 on printer
- Didn't have to change extruder direction
Happy Printing!!
