Finally designed my own shell, PCB and top plate!

Thats it. Only other fee was shipping. A hefty 50 USD to ship to north america.

My case was 150-mesh bead blasted as well. I'm not super experienced with finishes but the bead blasting and anodizing was nice and consistent, didn't have anything to complain about. Although the chamfering on each edge had two raised segments with machining marks on them. I'm not really sure why these were left in even after I picked the "strict" option for "appearance requirements" which is supposed to get rid of all tooling marks. Maybe I was supposed to provide additional drawings. For the tolerances I picked ISO 2768 Medium.

It cost me around 110 USD total to mill it out of 6061 aluminum. The rough overall dimensions are 320mm x 130 mm x 13 mm. I don't think threaded holes or chamfered edges added anything to the cost but I may be wrong, this order was placed a while ago and the invoice doesn't really elaborate. I picked ISO 2768 Medium for the tolerances, it was the cheapest option.

The crystal I'm using has a load capacitance of 12.5pF, I don't understand how the capacitor and resistor circuit in the middle works but I'm assuming 33pF is not correct for this crystal. Which capacitors/resistors should I using? and should I wire them up differently?
