Kossel 250 V-Slot 3D Printer - DIY Kit Nothing quite captures the imagination like a Delta style 3D printer in action. The UltiBots Kossel 250 V-Slot is a fun kit to assemble and print from. It has a 250mm heated bed with an aluminum heat spreader and Kapton Heater. This kit uses a PG35L geared motor directly mounted to the effector. Our Micro Extruder is compact, lightweight, and proven. It is unlike Bowden Tube style exctrude because the filament is fed directly into the HotEnds J-Head. Together with V-Slot extrusion and wheels this kit is straight forward and less complicated to build compared to many FFF 3D printe.
