New version of Bondtech BMG Prusa Upgrade MK3S/MK2.5S with RHD ver.C fan shroud.
I modified the original version model to be easy printable with FDM printers.
The original source: https://github.com/BondtechAB/Bondtech_Prusa_i3/tree/master/CAD-Files
It includes also the RHD ver.C Fan shroud (better than original IMHO) link: https://www.thingiverse.com/thing:3249344

This is the BOM list for the internal part:

1x Thread insert https://www.bondtech.se/en/product/thread-inserts/
1x Thumbscrew Assembly https://www.bondtech.se/en/product-category/spare-parts/thumbscrew-assembly/
1x 1.75 / 5.0 Bontech Drivergear kit. (No need if you own a MK3)
1x pancake motor with at least 16N.cm 1.8° or 0.9°
It need some modification of the firmware, i used the community firmware with LA1.5 from Vertigo235: https://github.com/vertigo235/Prusa-Firmware/releases
For the X carriage i suggest to use this from Vekoj: https://www.thingiverse.com/thing:3748932
Step files and F3d files are included.
UPDATE 1 31 August 2019 I added a body version (front and rear) and the hinge with 2mm recession to avoid using the threaded insert. These 3 stl file are marked "WITHOUT". Keep in mind that you will loose 1mm of lenght of the screw for the heatbreak fan as shown in the last picture.
