3D render pictures:
The case v1 is fully parametric and made with OpenSCAD, allowed me to make a online case generator. Link after the YSWS ends.
V2 is made with freecad, and is of top mount style.
I chose to not add any engraving since it will look bad. I would want to print my case In school with ams and custom colored fillament when I buy some new fillament. (I need hq to print my case in white for the moment)

The stabs are 22.38 USD so going to transfer 5$ to HQ. Done, https://hcb.hackclub.com/hackpad/donations - Chengyin Yao aka Cyao
Uhh I think the TX are still over budget? Gonna figure something out. Found in budget TX! Gonna abuse new member discount lol.
The LCSC cart might seem to have excess of some components, it's either: minimal quanitity, or at the end I could spend 2.7$ more to save 6$ so why not
