KRTframework built a custom hinge from scratch after extending a KTM fuel tank forward left the fuel cap buried under bodywork with no commercial solution that fit the available space.
The workflow is the real story here: 3D scan the existing bodywork, model the access panel around the scan data, design a hinge with enough travel to actually reach the cap, then 3D-print a bridging piece that integrates a push-to-open latch. Commenters immediately flagged the latch as a liability, arguing the push-to-open mechanism is too easy to trigger accidentally.
The full assembly breakdown is in the embedded video. Read this one for the design constraints, specifically how the hinge geometry was forced to solve for both tight packaging and wide opening angle simultaneously. That tradeoff is what makes the build technically interesting.
