PC Racing Handbrake and Button Box

thingiverse

This is a detailed guide to assembling a custom button box, likely used as a handbrake controller. The assembly involves printing various parts using an FDM 3D printer, such as a Printrbot Simple Wood with a larger bed. Here's a summarized version: ### Printed Parts List - **Base**: The main base of the device - **Handle Mount**: For attaching the handle to the base - **Potentiometer Mount**: For mounting the potentiometer - **Button Box**: For holding the buttons - **Bolt Mount**: Optional for mounting brackets ### Assembly Steps for Base and Handle: 1. **Sand Parts**: Sand the round sections of "Base", "Base Cover," and "Handle Mount" until they don't bind. 2. **Drill Holes if Necessary**: Make sure M6 bolts slide freely through holes in "Base". If they don't, drill out the holes slightly larger. 3. **Glue Nuts into Base**: Glue 2 of the M6 nuts into the hex holes in the bottom of the "Base". 4. **Attach Potentiometer**: Attach the potentiometer to the "Potentiometer Mount" using a nut and washer it comes with. 5. **Insert Rods**: Insert the rods into the handle parts, drilling if necessary for fitment. 6. **Assemble Handle**: Slide the rod into the slot on one of the handles and attach it to the other end. 7. **Mount Springs**: Screw M3 screws into the bottom of each "Handle Mount" for springs, then screw the other end of each spring into the "Base". ### Assembly Steps for Button Box: 1. **Attach PCBs**: Use PCB mount parts with spacers to hold the Teensy board in place. 2. **Mount Rear PCB Mount**: Screw the rear PCB mount into the PCB mounts and then into the box. 3. **Faceplate and Covers**: Use a template of the box to create faceplates and covers, cutting holes for buttons as necessary. ### Final Steps: - Attach the potentiometer cover - Solder wires to Teensy - Bolt the assembly to a mounting surface using M6 bolts This guide is comprehensive but might miss some detailed steps due to the nature of 3D printing and personal preference in assembly.
