After doing some research, I discovered that there is an alternative to silica that's more effective: activated alumina. It's relatively cheap when bought in bulk and can be regenerated easily in a normal oven. I discovered others had gone down this path before me and that quite a few were using powder shakers as desiccant containers that were all-metal and therefore oven-safe. For around $2.50, you can make a super effective desiccant pack that compares with some retail options that are 8x the cost! When they become ineffective at maintaining low humidity you can recharge them by tossing them in the oven at 400°F for a couple hours.

Today we got a little more snow and even colder temperatures.

Coming from Fusion 360, I was a little disappointed to see so many tutorials for threads in Onshape going deep into the details of thread geometry. If you've never built threads this way, I'd encourage it at least once because you will learn a lot and appreciate how much complexity there is with threads.

Thankfully you don't have to learn all of this to make perfect threads! The ThreadLab FeatureScript by Anthony Lu makes this about as simple as possible.
