Marvin with Improved Crotch

thingiverse

This is my take on the classic [3D Hubs Marvin keychain](https://www.thingiverse.com/thing:215703), with some thoughtful tweaks thrown in for good measure. I've always been a fan of this particular printing test because it presents several challenging aspects, but I noticed that my prints consistently showed a slight curl between the legs. The reason behind this phenomenon lies in the original model's design, which features an actual overhang in that area due to its spherical shape. As a result, unless you opt for supports during printing, one or more circles are left hanging in mid-air, refusing to solidify. I made some key adjustments to rectify this issue by replacing the overhanging zone with a bridge, allowing it to be printed flawlessly without any additional support structures. Additionally, I tweaked the small overhang between Marvin's eyes, which was another pesky part that required a horizontal line to be printed with one end anchored to thin air.
