Magic Pivot Business Card Dispenser

thingiverse

This business card dispenser features an eye-catching snap-on lid with no material at its axis, ensuring smooth rotation. When rotated, the oval hole aligns perfectly for easy card extraction using your thumb. Additionally, a small nub is included to securely hold the lid closed. Remember to adjust stl file orientations in your slicer and mirror parts appropriately to ensure proper functioning of the mechanism's catch feature. The pivot mechanism requires precise tolerances; therefore, two test files are provided to avoid wasting plastic. If issues arise, adjust print speed or examine extrusion levels. Aligning lid and base minimally while forcing ends together can facilitate snapping without damaging parts. Minimize overlap of the pivot mechanism for seamless assembly. Initially, the fit may be tight; clean sliding surfaces to ensure smooth operation. After use, apply WD-40 for added silkiness. Attach clear tape inside the base for improved card slide-out experience. Warping at corners may occur, so a heated bed is recommended for optimal results. Ear additions can reduce curling without a heated bed. Some users have experienced tight joints; files with widened grooves are available to address this issue.
