prusaprinters

<p>This housing holds the GaggiaBoard V3 from the Gaggiuino project.&nbsp;</p><p><strong>Variants:&nbsp;</strong><br>There are 4 different variants of the housing,</p><ul><li>GB_V3 Housing - Base model, easiest print. Cables from one direction, ST-Link to program Blackpill</li><li>GB_V3 Housing_Passthru - adds access to attach cables from either side&nbsp;</li><li>GB_V3 Housing_DFU - adds access to the USB-C port and buttons of the Blackpill for DFU programming</li><li>GB_V3 Housing_Passthru_DFU - combination of the previous two (shown in pictures)</li></ul><p>My recommendation: use an ST-Link for programming with GB_V3 Housing_Passthru.</p><p><strong>Assembly:</strong><br>There is a PCB latch (flexible member with a locating feature to hold the PCB in place). Pull down when inserting the PCB (there's a deflection limiter so you can't pull too far and break the beam).<br><img src="https://media.printables.com/media/prints/304637/rich_content/bf80c7ad-d8cc-4822-9349-fe3e7a993d16/image.png#%7B%22uuid%22%3A%228b073e0f-460b-4e75-8a86-243046e1129f%22%2C%22w%22%3A1804%2C%22h%22%3A835%7D">Depending on machine vibrations and placement location within the machine you may want to wrap silicone or Kapton tape around the body for extra security.</p><p><strong>Print recommendations:</strong><br>Print orientation as seen below, PETG, no supports, 0.4 nozzle, 0.2 mm layers, 3 wall lines, 20% Gyroid fill. If you have bed adhesion issues use a brim, but the PCB latch will be difficult to separate.&nbsp;<br><img src="https://media.printables.com/media/prints/304637/rich_content/b9dad3b7-e1ac-4300-997b-456dd07046bb/image.png#%7B%22uuid%22%3A%221fbd9854-caff-4839-85bc-77d021dab8ee%22%2C%22w%22%3A390%2C%22h%22%3A557%7D"></p><p><strong>Updates:</strong></p><ul><li>2022-10-31 - Increased clearance to Blackpill USB-C port by 0.4 mm</li></ul>
