With inspiration from davtr's Prusa i3 MK2-X build, The Hawk was born. For those unfamiliar with the MK2-X build, it is basically an amalgamation of Josef Prusa's i3 MK2 and the old RepRap RebeliX build. The theory is that the stronger frame of the RebeliX printer and the amazing mechanics of the MK2 can be combined to make the ultimate Prusa-style printer. That's our interpretation, anyway. Visit davtr's MK2-X page for more information. Our rendition of the printer includes fewer parts and a few design changes we found made our experience even better. Let's get to it!

UPDATE 7/09/2024: This is the method I used to guide the cables for the X and Y axis: https://www.printables.com/model/15904-prusa-i3-mk2s-no-mod-cable-chain-kit-all-axis

UPDATE 1 7/09/2018: We have now redesigned the Z-BOTTOM-MOUNT_V15, previously z-motor-mount, to be moved down by 3mm. This removes the issue of the PINDA probe hitting the right side mount and extra cooling fans from hitting the bolt heads. In addition the Z_Top_Mounts have been redesigned to use less filament, allow for tightening of the z-axis smooth rod by using an m3 bolt. The Z_BOTTOM_MOUNT_V15 has NOT been tested and has not been tested with the new top mounts.

The x-axis has also been successfully upgraded using designs from other thingiverse designs. X_END_IDLER_tensioning_idler_V15 is highly recommended for those of you looking for IsmaelPR1's x-idler/tensioner upgrade, but for Igus bearings. You will need to download his file and split the STL to get the actual tensioner, rod holder, and knob.

Also related to the x-axis is JKSniper's design of a Noctua fan upgrade. I wanted this but the X_MOTOR mount gets in the way when using Igus bearings. This is the link to the Noctua fan attachment upgrade I can highly recommend. The necessary upgraded X_END_MOTOR-tilted_Igus_clamps_V15 is in the files and MUST be used if the Igus bearings are used.

UPDATE 2 7/11/2018

The Z_TOP_MOUNT_V15 and Z_MOTOR_MOUNT_V15 files work, but with the wrap-around fan from Boby71 here the right side still just hits one of the mounting bolts. V17 of both the TOP mount and MOTOR mount will be updated. The top will also have a better way of applying force on the linear rod, ensuring it will not move up and down. All that is needed is an m3 hex nut and 8mm bolt for the left and right. The MOTOR mount is moved down and additional 1.5mm (4mm total) so the pinda and wraparound fan will have sufficient clearance. The Onshape files are available publicly at this link. Feel free to work with them as you wish, just update the community with any cool changes!
