Gig 'em Thumbs Up Pencil Holder
This was based of of Jacobcregger's design on TinkerCad: https://www.tinkercad.com/things/28p2R8zYnb4-thumbs-up-pencil-holder and customized using Tinkercad.
Print came out pretty good. I had to scale it down to print on my Micro M3D printer. Also, I ran out of red filament during printing, so I switched over to white mid-print (I'm sure that's not recommended by Micro)
