Touch Screen for Prusa MK3s, Octopi, Octoprint TFT

thingiverse

This is a housing for adding a touch screen with octopi / octoprint_tft to the Prusa MK3s. My printer is in a space constrained area so I needed to put the touch screen on the side of the printer. This one is designed to sit on top of the power supply and use two threaded holes on the back of the power supply. The housing fits: The touch screen: https://www.adafruit.com/product/2441 The Raspberry pi: https://www.adafruit.com/product/3055 A 40 mm fan: https://noctua.at/en/nf-a4x10-flx/specification A power switch: https://www.amazon.com/gp/product/B00AKUJNC6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 A barrel jack: https://www.amazon.com/dp/B06XRT5C2Q/ref=cm_sw_em_r_mt_dp_U_UN8ODbGH2YS81 I am powering this with a power adapter that I have added to the Prusa with this thing: https://www.thingiverse.com/thing:3865722 Notes on assembly: 1) Use just three screws to secure the touch screen. One of the holes is too close to the raspberry pi and the head of the screw will interfere with the pi if you put a screw there. 2) The leads on the switch i used were long so I bent them so they would not make contact with the raspberry pi. I also put a strip of electrical tape on the raspberry pi to provide some electrical insulation just in case. 3) Be wary of screw length. In some areas (for the fan and the touch screen), if the screw is too long you will deform the exterior face.
