This is a 3D printing guide for a remote-controlled vehicle (RCV) project. The guide provides instructions and recommendations for printing various parts of the RCV, including steering knuckles, steering rack, side plates, motor mount, servo mount, ESC mount, battery mount, front and rear bumper, drive gear, wheel hubs, tires, bottom plate, upper plate, cover, front cover finger, and rear cover finger. Here's a summary of the guide: **Required Print Settings:** * 100% infill for maximum strength * PETG or nylon filament for most parts (PLA can be used for less critical parts) **Parts to Print:** 1. **Steering knuckle positive/negative**: Sandwich together to mount front 625 bearings. Print at 100% infill with PETG or nylon filament. 2. **Steering rack**: Connects 9g servo to steering knuckles. Servo attaches with custom bent music wire (see attached photos for more information). 3. **Side plate**: Provides rigidity and direct airflow towards ESC. Print at 50% infill with any material. 4. **Motor mount**: Meets both side plates in a flush, clean transition to keep out unwanted grit and dust. Print at 100% infill with any material. 5. **Servo mount**: Securely mounts 9g servo to bottom plate. Use any material at 100% infill. 6. **ESC mount**: Secures 25a ESC to bottom plant. Use any material at 100% infill. 7. **Battery mount**: Snaps around battery to hold it in place and allow easy removal. Print in a highly flexible TPU such as Ninjaflex for best results. 8. **Battery tab**: Pull on the battery tab to lift up battery for easy removal. Print in a highly flexible TPU such as Ninjaflex for best results. 9. **Front & rear bumper**: Provides critical protection for steering knuckles. Print with a minimum of 50% infill and 3 shells in TPU. 10. **Drive gear**: Creates a roughly 5:1 gear ratio between motor and rear wheels. Print at 100% infill with at least 3 shells to maximize strength. 11. **Wheel hub**: Boasts an integrated suspension which greatly improves performance across various terrains. Print in TPU to allow spokes to flex. 12. **Tire**: Includes all terrain, slick, and sand tires. Print in an ultra flexible TPU filament such as Ninjaflex for best results. 13. **Bottom plate**: We have included STL and SVG files for the bottom plate so it can be milled, printed, or laser cut. Recommend using 1/16” birch ply or 50% infill PETG for best results. 14. **Upper plate**: Use the same materials as the bottom plate. Both STL and SVG files are included. 15. **Cover**: Keeps electronics in and dust out! Print, cut, or mill in any material 1/16" in thickness. 16. **Front cover finger**: Bolts into upper plate and provides a place to bolt cover in place. 17. **Rear cover finger**: Holds the back of cover in place. **Tips and Recommendations:** * Use M3x4 knurled insert nuts for mounting. * Insert nuts easily using a soldering iron. * Print parts with high infill percentage (100% or 50%) for maximum strength. * Use TPU filament for flexible parts such as battery tab, wheel hub, and tire. * Use PETG or nylon filament for most other parts. * Use PLA for less critical parts.
