Colder one on top, body-temp one bottom.

I used it to print these whistle bottle openers:

That might start getting confusing after quite a few bottles were consumed..
Where did you say that purple bottle opener was again...

This is the highest number of parts and the largest (in X / Y) build-plate area I've printed to date!

I've been printing a bunch of these for my buddy who wants to take them to a party in Vegas with his friends.

I started with groups of 6 and then decided to go big with a group of 20 (6.5 hours).

The first time I printed 20, I ran into a problem where the print completely stopped at the 4 hour mark...

I was printing from SD card and everything seemed fine. After a bit of digging, I realized I had accidentally left a CURA extension I was testing to change the filament at the 5mm height. (this: https://www.youtube.com/watch?v=OG2adhJgkgI )

Once I removed that, everything worked fine.
