Today I used the MakerBot to print an armature mount for the vacuum chamber.
The ring is larger than the build platform, so I made four pieces that dovetail together.
I used Jag’s dovetail library.
The MakerBot makes it ok to fail. I went through five designs before I arrived at this one that works. But that’s ok!

How will the extruded plastic behave under vacuum? How much will it outgas and will that foul anything?
We will see!
I’d also be curious how it erodes. Plastics tend to get pretty eaten up by high temp particles whacking in to them. Being able to print a new one when that happens is pretty neat.
Really enjoying your MakerBot posts.
I suspect it won’t be great in a plasma. But at the moment I only need to run a plasma a few second at a time.
Yeah what are you doing? I assume you’re a bit short of parts
and need a solution. Is this a template for something you will
have made?
This is the first step towards a mounting system.
