GPU reballing jig

Top part is universal but i have it in different sizes for 3060-4080 and 3080-4090 as well as 7900 labeled.
5090 stencil is not the same as the rest, it uses 120x120 stencil. Will make 90x90 version soon
Base is for specific series chips
Using 10x2mm magnets to hold the stencil attached to the top.
Stencil cutout is slightly oversized to allow small adjustments.
Chip will stay centered by the tension coming from 4 posts around it so it will not fall out. At least in theory.

The accidental drain preventer is basically what it is. It adds a small slope so its harder for balls to escape while you shake the whole thing.
that piece is printed separately and glued in place into the top part
Make sure it fits perfectly flat. If it does not, sand it down with a sand paper and test the fit before gluing in place.
