After watching Wemy videos for second time, firgured out that I had wrong 3D parts (see photo) because I would be using a 2.2" screen with welded wires instead of 2.4" screen with ribbon attachement. So reached out to Wermy who shipped out the right 3D parts for 2.2" screen half.
First order of business was preparing the tin. Used a small one hand dremel I got from my local electronic store and a 3D printed guide Wermy sent me. Worked out good and fast very pleased with result. Will be doing small adjustments with hand file later when I get parts for final fitting.
Next up fusing the pi Zero to the board. Very nervous because first time welding. Took advice and practiced a bit on other parts but visibly not enough because after testing continuity, I had to start over a few points thats why you see darker marks where it got hot. Changing for smaller pin tip on welder helped solder to reach bottom board.
After following conversation on Discord, learned Helder had a few Low Battery Monitor PCB so ordered one of those and installed it.
Getting better with iron.
Got a local guy to print extra 3D parts. I got the STL files for the print from the "FAQ" section on the Wiki build page here:
https://www.sudomod.com/wiki/index.php? ... intyPi#FAQ
The quality was far from Wermy parts but for the price, can't complain. Printing 23 g is very cheap.
Since I have extra parts, ordered second kit this time from Helder with 2.4" screen and ribbon attachment. Not much difference between 2.2 and 2.4 screen.
The 2.2" screen did not fit 3D parts as is so needed to remove SD card reader and pins. Better to snap off pins then cut. If you cut, you will need to file them down for fitting.
If you keep screen board, 3D screen holder needs small modification in left screw corners to fit screen in.
You could always change 3D model before print or other option is to use a minimal board iliPlate from OSH Park like this one I was told would also work. https://oshpark.com/shared_projects/zUNmnlLF
I decided to kept screen board to save cost and also am thinking is safer to weld to wires instead of ribbon considering my newly learned skills. To make it work (fit), I also had to cut corner of board where screws where landing.
Thats it for now waiting on parts.
