Memory and PTT Keyer Box for Icom IC-7300 and others
thingiverse
This design is based on chunter952's original concept. I've modified it to suit my needs, giving the box a slightly lower height for improved wrist and hand support. The switches are made of stainless steel, each with a diameter of 20mm, and I've added a PTT switch and a 3.5mm audio jack for a foot pedal. Another version featuring four arcade buttons is also on my mind. Inside the box, a 1mm lead sheet at the bottom provides additional weight, making it easier to press the buttons firmly. For the connections, I followed this guide: https://en.golb.be/icom-ic-7300-external-keyboard/. If needed, you can secure the top to the bottom with a small drop of clear adhesive glue in opposite corners from inside. As for aesthetics, I left them as printed, but you can give it a polished look by applying a filler primer and your preferred paint color.
