Eyeball Bowler

thingiverse

Here is a 3D print design for an Eyeball Bowler tutorial, found on Adafruit's website. My video of this project can be viewed here: https://www.youtube.com/watch?v=CsEU-dP8dx8 I used a Teensy 3.2 and Adafruit's 1.44" Color TFT LCD Display. Additional components needed for this project are listed in the tutorial. I discovered a small round lens, about 1 inch in diameter, in the jewelry section at my local hobby store. While it's smaller than described in the tutorial and not a perfect half circle, I think it adds to its charm. To create this display holder, you'll need to make a few modifications to the cover design. I decided not to cut out any holes or hide components inside the hat band. This holder holds both the LCD screen and lens in place atop the hat band. Underneath the cover and behind the band, a small slit allows for easy passage of the ribbon cable. For easy access, I attached my Teensy 3.2 and battery to the inside top surface of the hat using velcro strips. Plenty of room is left over inside. Here are some specific printing settings: Rafts = No; Supports = None; Resolution = .2 mm; Infill percentage = 20%. Printing is done in a flat orientation with no supports. I designed this print to include two thin, solid layers so my printer could bridge the gaps without the need for any extra material. You'll still need to manually remove one of these layers to fit around the center lens hole and drill out the mounting holes on the inside layer. Feel free to use and modify my 123D file, as included below.
