OpenVTX flashing jig

This is a jig for flashing the <a href="https://www.aliexpress.com/item/4000938942385.html"> EWRF E7082VM </a>version 2 VTXs. The VTX has very small pads, particularly the CLK and DIO ones and I actually ripped one of them when trying to solder some wires so I decided to design this jig. I use two types of pogo pins: <a href="https://www.aliexpress.com/item/4000086379418.html?spm=a2g0s.9042311.0.0.f7144c4dQagnwk"> 0.68 mm</a> for the CLK and DIO pads and <a href="https://www.aliexpress.com/item/4001095875130.html?spm=a2g0s.9042311.0.0.f7144c4dQagnwk">1.02 mm</a> for the V, A, - and + pads. For the axis I use a M2 x 16mm. For the spring I used a 3/8" x 3/4" spring from this <a href="https://www.amazon.com.mx/gp/product/B000K7M36W/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1"> box</a>. However, it will work without a spring. There are two versions for the top part, anyone will work the difference is that V2 has more space to solder wires. Only the top part requires supports and I recommend to print it as shown in the STL (on its side) with 0.12mm layer height to have better holes. You can solder wires directly to the pogo pins.
