Drews Rostock Skeleton Head Free 3D print model

This is a revised mod made for my Rostock-derived 3D printer. The goal was to create a hot end carriage that strikes the perfect balance between minimalist structure and functionality, accommodating three mini 20mm fans, LEDs, wire guides, and the mini J-head hot end. I note that my delta platform geometry differs from a standard Rostock setup, necessitating adjustments in other parts of the printer for optimal performance. To this end, I shifted the rod end holes on the carriage a quarter inch closer to the hot end to minimize weight and size while preserving component integration. Before assembling this piece, make sure you have one of each necessary part. The 'Clip' is securely seated in the groove of the hot end, followed by screwing an SMC KQ2H04-01AS push-fit connector for the Bowden tube into the 'Upper' part, printed upside-down relative to its final placement on the printer. Press the larger hole over the J-head's top from within the 'Upper' part. Line up three smaller, inner holes on the 'Upper' with those on the 'Clip.' Three 3mm hex nuts fit snugly into the Lower part's pockets, while using three 3mm screws to connect the parts – through Upper and Clip, securely anchoring them to Lower. Eighty millimeter long M3 threaded rods run through both the outside of the Lower part and Traxxis rod ends on the connecting rods, with washers between the plastic and rod ends to stabilize movement. Once these threaded rods are in place, install three 20mm fans under the carriage, directed towards the hot end for optimal bridging performance. A major modification includes the direct airflow above the printer frame – a change I no longer utilize fans blowing directly on the head, keeping it cooler via exposed hot end fins and an open-sided structure. Additional details include three LED slots useful for diagnosing issues; they illuminate as the plastic emerges from or is not cooled by the nozzle properly. For proper wiring management, I've included spaces to direct thermister wires to the hot end's heater component and other essentials securely. To prevent thermal issues and keep everything organized, carefully secure thermister and power cables – attach fan cables to lower framework using provided clips, ensuring all essential elements run smoothly and effectively during operation
