3D model BMG extruder for 3D printer

Hello!
I sell a 3D model of BMG extruder for a 3D printer.

There are 2 folders in the archive:
- BONUS FILES - these are the sources of the 3D extruder model, with which you can edit it completely, if necessary.
- STL for printing PLA-PETG - files are calculated with shrinkage of 0.2 mm (I do not recommend using ABS plastic, it gives a lot of shrinkage)

What you need to build:
- gears cheap Mellow $ 8.68 http://ali.pub/3xt7z6
or high-quality gears $ 16.81 http://ali.pub/3xt86d
- Gear and motor gears $ 4 http://ali.pub/3xt8hu
- bearings MR85 ZZ $ 1.67 http://ali.pub/3xt8uv
- two rods with a diameter of 3mm, length 20 and 32mm
