4volt design with a small gap

thingiverse

I've noticed how many enthusiasts have been contributing to repositories or libraries. If you're interested in knowing where this project originated from, check out the original version on http://www.thingiverse.com/thing:137367 . This particular remake features a slight refinement compared to its predecessor. Most printers aren't capable of producing holes that are perfectly sized to allow small parts to pass through with ease, so I made some adjustments to account for this limitation at the design stage. In hindsight, including a gap in the original version turned out to be a more effective solution, albeit unintentionally. Regarding the 3D model file itself, it's worth noting that it may not conform to standard conventions for clean designs. That being said, one of the primary objectives was to demonstrate how Slic3r functions, highlighting its potential for problem-solving in specific situations. To be more precise, when dealing with boolean operations that don't yield the desired outcome, experiment with flipping the surface polarity in the slic3r algorithm. You'll find that the slicer software is clever enough to automatically remove unwanted portions by opening up these negative areas. This technique exploits a counterintuitive property inherent in non-manifold meshes, showcasing the innovative applications of Slic3r beyond conventional use cases.
