prusaprinters

<p>This is a remix of the Original Bondtech BMG Upgrade extruder to integrate the new MK3S filament sensor. Work only for Bear X axis.<br/> I did also some modifications to be friendly printable with FDM printer.<br/> I added a version of the extruder body with a square nut instead of the M3 threaded insert , if you choose to print this version you have to use in combination with "Hinge with 2 mm recession".<br/> I included n°2 versions of the sensor's cover to use with PC4-M6 or PC4-M10.<br/> This design include the Bear X_carriage modified,<br/> for more info look at <a href="https://github.com/gregsaun/bear_extruder_and_x_axis/tree/master/optional_parts/bondtech_x_carriage">https://github.com/gregsaun/bear_extruder_and_x_axis/tree/master/optional_parts/bondtech_x_carriage</a><br/> For the Zaribo X-carrige you have to use this : <a href="https://www.thingiverse.com/thing:3472470">https://www.thingiverse.com/thing:3472470</a></p> <p>This is the BOM list for the internal part:</p> <p>1x Prusa MK3 to MK3S upgrade <a href="https://shop.prusa3d.com/en/printer-upgrades/898-original-prusa-i3-mk3-to-mk3s-upgrade-kit.html">https://shop.prusa3d.com/en/printer-upgrades/898-original-prusa-i3-mk3-to-mk3s-upgrade-kit.html</a><br/> 1x Shaft Assembly <a href="https://www.bondtech.se/en/product/shaft-assembly">https://www.bondtech.se/en/product/shaft-assembly</a><br/> 1x Motor Gear <a href="https://www.bondtech.se/en/product/motor-gear/">https://www.bondtech.se/en/product/motor-gear/</a><br/> 1x 3X32 mm Shaft <a href="https://www.bondtech.se/en/product/shafts/">https://www.bondtech.se/en/product/shafts/</a><br/> 1x Thread insert <a href="https://www.bondtech.se/en/product/thread-inserts/">https://www.bondtech.se/en/product/thread-inserts/</a><br/> 1x Thumbscrew Assembly <a href="https://www.bondtech.se/en/product-category/spare-parts/thumbscrew-assembly/">https://www.bondtech.se/en/product-category/spare-parts/thumbscrew-assembly/</a><br/> 1x 1.75 / 5.0 Bontech Drivergear kit.
