<p>This is a basic model of a bottom plate for a Ghostbusters proton pack. The plate follows dimensions from Stefan Otto's published blueprints–i.e., 39.3mm x 69.8mm x 12.7mm.</p> <p><a href="https://www.gbfans.com/w/images/4/4e/Stefan%27s_Proton_Pack_Plans_Page_2.jpg">https://www.gbfans.com/w/images/4/4e/Stefan%27s_Proton_Pack_Plans_Page_2.jpg</a></p> <p>This plate is special because it includes a slot for a USB extension. The slot is sized for this particular extension with ABS shrinkage in mind:</p> <p><a href="https://www.amazon.com/gp/product/B07LB4F9V7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1">https://www.amazon.com/gp/product/B07LB4F9V7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1</a></p> <p>The extension can be used for charging or programming internal electronics. The extension fits snugly into the slot but can be secured with screws.</p> <p>The screw holes are sized to fit M3 press-fit threaded inserts from McMaster Carr:</p> <p><a href="https://www.mcmaster.com/94510A030/">https://www.mcmaster.com/94510A030/</a></p> <p>I have included the Fusion 360 archive file and a .step file if you want to resize the slot for PLA or change the slot or screw holes.</p> <h3>Print instructions</h3><p>Print the plate however you see fit. You can print it with 2-3 perimeters and 5-10% gyroid infill. Those settings will create a strong plate you can sand and finish.</p> <p>If you intend to use heat inserts for the screws, print the plate 1-2 additional perimeters.</p>
