I’ve just managed to get my Monster Kossel v2 design printing - and a perfect print right off the bat to boot with a Kossel calibration card.
Design is shared under the GPL, for tinkerers who know how to build a printer (no, it’s not a kit, I don’t have the time to write a full-fledged manual unfortunately): https://www.thingiverse.com/thing:2854236
The interesting bit on my machine is a custom-designed remote-drive 2-in-1 extruder system giving direct-extrusion performance while keeping the printhead lighter than an i3’s.
Details are on Thingiverse as to the details, but short story is: 350mm bed, 400mm tall printable volume, powered by a Replicape, noctua 40mm fans on electronics and effector (hotend+part cooling) for maximum stealth while in operation.
