XR2206 Signal Generator Improved Case

thingiverse

Improved case for XR2206 based Signal Generator kits can be found in various places online, including Amazon, where you can purchase a kit with an included acrylic case that needs improvement. This new case replaces the entire original case except for the front panel, as reproducing its labeling is difficult. Assembly of this improved case involves following these steps: 1. Begin by attaching short screws and nuts to the board in pre-drilled holes at the corners. These serve as stand-offs, as shown in the second picture. 2. Next, insert the board into the middle of the new case. The screw should pass through the nut and fit into one of the four holes below. 3. Carefully place the acrylic plate with the labeling on top. It may require some effort to get it to fit properly due to tight tolerances. 4. Using M3x20 bolts and nuts, secure the bottom area by placing the nuts in designated spaces. Then, pass the bolts through the acrylic plate's holes, into the case, and finally tighten them down. 5. Finally, attach the included knobs to the potentiometers on the board. To ensure a successful print, make sure your printer is calibrated accurately, as tolerances for this design are relatively tight. If you wish to modify this design, a SolidWorks part file is provided for reference. The file's version number (V6) reflects the number of attempts it took to achieve the desired result.
