My Kossel v-slot 250 built from parts. Got most of parts from Ultibots. Great company and very helpful. I printed the plastic parts on my Flashforge Creator pro. Purchased 24v PS, E3DV6, 24v heatbed, Azteeg X5v2, Viki2.0 lcd, Magball CF arms, PG35L-048extruder motor, Nema17 0.9 steppers. Designed some parts myself. Great printing machine.
