Terminal Block Box - Two Wire

prusaprinters

<p>I had a need to fit some lighting fittings. &nbsp;The wiring is simply via screw blocks. &nbsp;Instead of using purpose built terminal blocks (of which I had none on hand), I designed and printed a couple of custom screw terminal block boxes. &nbsp;The box serves the purpose to keep them electrically safe from their surrounds.</p><p>The box design consists of two halves. &nbsp;There are cutout openings for a pair of power wires to feed from either side of the box. &nbsp;The box is designed to work with a standard 20mm screw block. &nbsp;The fitted case is intended to be left loose in the working space (ahhh!) or perhaps, can be secured with double side tape to the nearest rafter.</p><p>The box two halves press together with a friction fit. &nbsp;To ensure that the halves don't unexpectedly separate over time, a single 3.5mm x 20mm self-tapping screw secures the parts together.</p><p>My print is made with TPU 1.75mm Aurarum purple filament, with 0.2mm layer height and 15% infill on a PRUSA I3 MK3S printer. &nbsp;No printing rafts nor supports required.</p><p>I hope you can find this print useful, too.</p><p>Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.</p>
