I am tring to work out how many layers of laser cut acrylic I will need, in total. I am using 2mm acrylic.
At the moment I have six layers:-
It would be nice to reduce this down by one or two. Limiting factors:-
- Two x Cell battery CR1216 12.5 × 1.6 height total: 3.2mm
- PCB Thinkness 0.6 to 0.8mm thickness Total 0.8mm
- Switch - found a lovely switch 1.2mm height
Giving at least 5.2mm, which means I can not (thanks to the switch) fit everything in just 5 layers. Top, bottom and 6mm inners. Time to sketch the PCB in https://www.tinkercad.com/
