PiGRRL Zero XL

thingiverse

Made for use with a 3.5-inch TFT backup monitor available on Amazon at https://www.amazon.com/BW-3-5-Inch-Monitor-Automobile/dp/B0045IIZKU/ref=sr_1_2?ie=UTF8&qid=1479809012&sr=8-2&keywords=3.5+tft. Also, since a slightly bigger case is needed, the bigger Lipo battery from Adafruit can be used effectively. If you use the recommended screen, GreatScott! on YouTube has a tutorial for a Pi handheld that shows how to modify the screen for 5v instead of 12v. Install the image from Adafruit and replace the stock config.txt with the one included. The buttons from other remixes that worked well are also included. Using these buttons for start, select, and exit: https://www.amazon.com/gp/product/B00LVMK6UK/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. Everything else should be straightforward like in Adafruit's tutorials. Print Settings: Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: No Supports: No Resolution: .2mm Infill: 15% Notes: This print should be easy, but if the joint is weak, decrease the layer height to get more adhesion and plastic per mm.
