November 2021 UFO


Congrats to Chad D. (I think? I forgot to write it down and going by memory... Chad confirm! lol
for winning the November 2021 Mothership Box!

This month, the Mothership prize is a Z-Catch nozzle removal tool! The last of it's kind as far as I know. Z-Catch is no longer producing the tool.

Bonus Accessory!

Z-Catch Vanadium Socket Set

The first ever repeat accessory - for those who got them previously, I hope you are still happy with it! Z-Catch is a great company with great products, however they may not be around much longer and I offered to help clear out some of their stock.

Bonus Project!

Digital Hourglass

Past November boxes have had what I called "Turkey projects" they were mostly useless projects meant to be funny. This year I wanted to do something for real, and I hope you like it!

  1. great project – after making and digging into the code though I found it came from a project that had an encoder in it so that you could set the time. I am thinking about a redesign to take advantage of that so that it would be more useful in game playing . But great design and project! Thanks – Looking forward to things to come 🙂 posted picture on Prusa prints of my hourglass
