Rostock Mini "Phoenix" Effector

thingiverse

This is a modified delta effector for the Rostock Mini, specifically designed to overcome space constraints on this compact printer model. One of the main challenges with the Rostock Mini's small size is finding enough room on the effector for various accessories. To address this issue, I employed three key design strategies: 1. Combined the platform and jhead groove mount into a single part, effectively lowering the jhead by several millimeters to create additional space below the platform. This modification also made the platform more rigid. 2. Added a fan mount that accommodates a 30mm fan for the cool end, allowing for efficient airflow while minimizing interference with the nozzle/hotend. 3. Installed a z-axis autoprobe mount below the platform to avoid clearance issues with the diagonal rods on the top side. The new design ensures that the fan supports are positioned close to the nozzle/hotend without causing any issues, as long as the fan is installed and moving sufficient air. In my tests, I ran the effector up to 230C with PLA material, and the results were satisfactory. To ensure proper installation and optimal performance, please note the following print settings: Printer Brand: RepRap Printer Model: Rostock Mini Rafts: No Supports: Yes Resolution: .35mm nozzle, .2mm layers Infill: 20% Full Honeycomb During printing, make sure to orient the part upside-down. Sometimes, STL files can get into incorrect orientations. Post-printing, you will need to secure the fan using 4x M3 machine screws and nuts. The top mount is attached to the platform with 2x M4 screws and nuts, while the microswitch is held in place with 2x M3 screws. One of these screws requires a shorter length due to clearance constraints. For the safety pin, please refer to my video for proper bending techniques. It's also essential to temper the pin after bending to ensure its stability. If you need to adjust the safety pin hole, simply heat the pin or use an additional pin to create a new hole. In my setup, I used a 1/8" brass rod as the probe rod, which was bent at a 90-degree angle. If your bend is not sharp enough, you may need to Bubba the inside radius with a Dremel to facilitate smooth movement of the probe rod. The spring used in this design is from a ballpoint pen and provides sufficient force to actuate the switch and deploy the probe when clearances are correct. This delta effector was designed using Blender, where I employed mockup parts for the jhead, fans, and switches to verify fit. Additionally, I utilized a Rostock Mini design template with predefined endpoints for the six diagonal arms and necessary clearance cones above these points.
