Case for RepRapDiscount Smart Controller

thingiverse

This design from reprapdiscount (http://www.thingiverse.com/thing:26093) caught my eye, but I couldn't modify it to be printable. So, I decided to make my own version, incorporating a fantastic professional-made mini elastic kill button. However, while creating the case, I didn't have the LDC board or LCD. To ensure a perfect fit, "Hardwarekiller" provided me with accurate measurements via email. To create a flatter appearance and conceal potential impressions, I added an external channel between the top and bottom parts. Due to slight variations in LCD sizes, despite similar appearances, I designed two distinct top case variants with different display cutouts: 98.4 x 40.4 mm and 97.4 x 40.4 mm. Moreover, there are two bottom case options - one with cable slots on the front side only, and another with slots on both the front and back sides. The latter is 0.5 mm taller to provide additional space for cables between the controller board and the bottom. The bottom part includes multiple screw nut recesses for adjustable case mounting. If using an 8 mm rod, you can utilize case clamps. When installing the kill button (8.5 mm), it will protrude 0.5 mm, making it easier to push. For assembly, you'll need four M3 x 12 screws with nuts, four M3 x 20 screws with nuts, and two self-tapping 2 mm x 5 screws (for the button, though it works without tightening). To lower the controller knob, shorten the thread by about 4 mm. An edit on December 29th highlights a printed controller case using a different knob by "MikeP-NZ." This thinner knob is more practical due to its faster rotation. Consequently, I designed one like it and enjoy using it already. Lastly, an update on May 3rd includes a new "controller knob 6.4" with an inner diameter of 6.4 mm, which is 0.1 mm larger.
