Version 4.51 silicone button array development

Research and development continues with cutting (and recutting, and recutting) the new silicone button casting mold. I’ll be verifying the dimensions tonight, but things are moving along nicely. I may be able to get one of the new v4.51 boards close to fully assembled. Which I am very
much looking forward to. The last major task is to engineer a jig to hold a dremel flex shaft that will attach to my cnc machine. This will let me cut a hole for the USB jack with precision and repeatability on the case. After that, I’ll be able to kick into a higher gear for producing units and kits. Whew!

a sea of machineable wax chips. This mold would end in disaster.

Try number 3. This one went well after 5 days of chipping away at it.
