Model Overview & Print Notes
English Description –
This PETG-printed Creality K1 top upgrade replaces the original upper frame, creating additional clearance for filament guidance and tubing routing. The design features a slim, rectangular mounting frame with reinforced corners, integrated screw and magnet mounts, and a hinged, transparent lid that can be fully opened for maintenance. The elevated geometry prevents filament friction at the entry point, improves the bend radius, and enables smoother filament movement during high-speed printing. The frame mounts directly to the printer housing with screws and optional magnets, maintaining a clean, factory-like appearance while expanding the operational space above the toolhead.

German Description –
This PETG-printed Creality K1 upgrade replaces the original upper frame, providing significantly more space for filament guidance and the Bowden/PTFE tube. The design consists of a slim, rectangular attachment frame with reinforced corners, integrated screw and magnet mounts, and a hinged, transparent lid that can be fully opened for maintenance and interventions. The raised geometry reduces friction at the filament inlet, improves the filament bend radius, and ensures smoother, more reliable feeding at high printing speeds. The attachment mounts directly onto the printer housing, preserving a clean, near-factory look while significantly enhancing functionality.
⚠️ Note: This model is intended exclusively as a functional printer upgrade or organizational component and is not a toy, safety device, or load-bearing structure.
🖨️ PETG Printing Tips:
Layer height: 0.20–0.24 mm for stable functional parts; Infill: 20–35% (Gyroid or Grid); Support structures: Enable only on hinge mounts, magnet pockets, and overhangs;
Nozzle: 235–250 °C; Bed: 70–85 °C;
Cooling: 0–30% (too much fan weakens PETG);
Walls: 4–5 outer walls for screw and magnet strength;
Tolerance: 0.35–0.45 mm for moving parts (lid, hinge);
Adhesion: 5–8 mm brim recommended;
Optional: Brass threaded inserts or embedded magnets for durable mounting, lightly grease hinge axes.
