USB Load Tester Case

prusaprinters

<p>A case I designed to suit a cheap USB Load Tester purchased from AliExpress. Those resistors get very, VERY hot in use, so something was needed to keep fingers, animals, flammables, etc, away from them.</p><p>Holes are also provided on the under side for test probes.</p><p>&nbsp;</p><p>Accuracy is key. The joints are all designed to provide only a 0.1mm to 0.2mm gap, but if an Ender-2 can do it than any modern printer should be able to. It's still a decently tight fit, however, so be prepared to use a little force to get it all together; just not so much that you separate the layers.</p><p>Supports are not required - the maximum angle is 45° and the bridges are under 5mm long.</p><p>Regular PLA may not be suitable for prolonged use due to the heat the resistors give off. I've had no issues so far with PLA+.</p>
