Sandmann E512 harvester TV edition

thingiverse

It appears you've provided a worklog for creating a 3D printed replica of an E512 Harvester/Combine, specifically the Sandmann TV edition. Here's a summary and some observations: 1. **Design Evolution**: You've mentioned several design iterations, starting with a single base part that combines parts 1 and 2, reducing material usage and printing time. Later versions have increased thickness for added stability. 2. **Printer Limitations**: The piece is quite large (215x81mm), which might be challenging to print on smaller printers without extensive post-processing or modifications to the design. 3. **Details and Accessories**: You plan to add details such as headlights, tail lights bar grooves, mount holes for parts like the rotary cutter, and potentially a trailer for transporting it. The use of toothpicks for small joints is an interesting approach for adding structural integrity without excessive printing or gluing. 4. **History and Inspiration**: The original E512 was manufactured by Fortschritt in Saxonia/GDR starting from 1968. It's known for its reliability and simplicity, with many still operational today due to the availability of basic tools and minimal spare parts costs. 5. **Scale and Size**: You're working at a scale that requires adjustments due to space constraints, but you aim to keep it as close as possible to the original dimensions. 6. **Parts Variations**: Some parts exist in two configurations, suggesting an interactive design tool or careful consideration before each print is necessary. 7. **Future Plans**: The rotary cutter and its holder are planned for a material change (steel spokes or similar), and there's talk of designing covers for compartments used for storing harvested goods and the engine. 8. **Optional Design Elements**: The cabine could be omitted, replaced with acrylic plates and sliding windows, or even made entirely from acrylic for a more detailed model. This project seems to combine historical accuracy, technical challenge, and creative problem-solving in 3D printing. It's a complex endeavor that requires patience, attention to detail, and likely some trial and error to achieve the desired level of fidelity to the original machine.
