Bondtech Prusa 3 Extruder - FDM Printable - MK3 \ MK2 BMG

thingiverse

This is a remix for the Bondtech Prusa i3 official extruder . I remixed it to make it easier to print parts with FDM printers, since Bondtech prints them using SLS technology. I replaced all brass inserts from the original design with square nuts like those in the stock extruder. I also included a nut version for the main hinge, in case someone doesn't want to source a 3x32mm shaft. Thanks go out to Martin Bondéus and his team, as well as Grégoire Saunier from the Bear project & Olof Ogland, who created the original design. It's a great base that they made open-source for the community. Parts needed: M3 screws in various sizes: 1x45mm, 2x40mm, 1x25mm, 2x20mm, 1x15mm, 6x12mm, 1x10mm, and 3x8mm. Two 5X8X2.5 bearings (https://www.bondtech.se/en/product/ballbearing-5x8x2-5). One shaft assembly (https://www.bondtech.se/en/product/shaft-assembly). One motor gear (https://www.bondtech.se/en/product/motor-gear/). One 3X32 mm shaft (https://www.bondtech.se/en/product/shafts/) or a 3mm bolt, if you print the optional non-shaft extruder cover. One thread insert (https://www.bondtech.se/en/product/thread-inserts/). One thumbscrew assembly (https://www.bondtech.se/en/product-category/spare-parts/thumbscrew-assembly/). One Bondtech driver gear kit for 1.75 or 5.0 mm filament (https://www.bondtech.se/en/product/drivegear-kits/) - you don't need this if you own a MK3.
