This is a spool adapter for the Kossel Pro. It mounts to an aluminum 1515 OpenBeam extrusion using two M3 x 6mm BHCS (or the longer M3 x 8mm SHCS) that are included in the Kossel Pro kit.
Version two of the original spool adapter adds three different mounting types for different cold end orientations (keeping the upright orientation, and adding two different side orientations).
Being just an adapter, you'll need compatible spool holders, and these come in various shapes and sizes. Look below under the 'tested with' for more information.
30% infill, .2 layers. Orient the print so that it is face down with the side holes printed last.
Mounting hardware/instructions:
2x M3 x 6mm BHCS OR 2x M3 x 8mm SHCS
and
2x M3 nuts
Pre-threading things onto the adapter is recommended to take up any tolerances in printing, as well as making the actual mounting easier.
Installation is best done with the printer on it's side. Insert the hex nuts, and pre-insert the screws into the printed holder. Line everything up and secure with the appropriate driver.
