(Thin w/Lip) iPhone 5 Gear Case with Geneva mechanism

thingiverse

This is a unique mashup of the Thinner iPhone 5 gear case by OleEichhorn (http://www.thingiverse.com/thing:464950), which itself was inspired by the remix of BrandonW6's (http://www.thingiverse.com/thing:79606) iPhone 5 gear case, based on QuentinT's innovative iPhone 4 gear case (http://www.thingiverse.com/thing:65810). The look and slender build of Ole's remix won me over, but I felt it was lacking an essential element for any decent iPhone case: a protective lip around the screen to safeguard against accidental drops. To fill this gap, I added a 1mm tall lip that rises just 1mm above the front glass, preventing potential screen cracks should the phone slip out of my hands. This modification has been carefully incorporated onto only the straight edges of the frame, allowing users to easily remove and reinstall the case without complications. The sole alteration from Ole's original design lies in the custom-made case frame. All components are identical to those found in Ole's design except for this newly added frame feature. Despite being originally designed with PLA material in mind, I printed the entire structure in ABS without encountering any shrinkage issues during processing. However, all pin functionality remains intact, and a light sanding is suggested for insertion purposes. Users should take note that separate printing of pins may yield imperfect results. For optimal assembly success, it is essential to follow the instructions closely: You will require one set of each part, with the chuck's optional attachment allowed if desired. Printing both the gears and pins on the same project with a solid raft provides an aesthetically pleasing outcome. Individual printing of these delicate components can sometimes produce undesirable textures. As a matter of necessity, please pay attention to these crucial assembly instructions: All 'upper level' gears rely exclusively on small pins, whereas the smaller, dual-layer gear operates on larger big pins and a distinct main pin. This distinction necessitates minimal sanding before installation to prevent jamming issues. It is worth noting that even with proper installation, there's an initial need for minor touch-ups before successful operation. In particular, the gears may be more stubborn during their initial setup; in this case, some moderate grit sandpaper is your best bet to create optimal smooth operation. Test every component prior to complete assembly, verifying each part rotates without incident, no matter how hard or tricky it feels initially. Make a gentle application of finer abrasives when necessary. When attaching the frame and the gears together, ensure to use robust superglue and apply it in moderation so not too much extra residue seeps onto surfaces adjacent areas. Once complete and all components solidify into place (you can even take a small power drill and run it by means of some chuck for better efficiency - especially ideal once you start operating the gear set). Any issues arise or further concerns come your way - I shall offer any further advice and answer every inquiry promptly to ensure a successful, worry-free usage of your custom-crafted i- Case!
