Looks pretty clean. Is that PLA?
Thanks, ya, PLA.
Let me know how it holds up. I've only ever used ABS for this part, and I wonder how the PLA will handle the radiant heat from the block. I would definitely use an insulator.
An insulator was definitely part of the plan, but now that you've released the Itty Bitty, I'm thinking of skipping this upgrade, unless I have to step back down from the Itty Bitty.
