Valentine Heart

thingiverse

The original design, Secret Heart (44579), was crafted specifically for Makerbot and worked flawlessly. However, I encountered issues when attempting to print on other devices. To address this, they released an OpenSCAD file, which I updated to the current version and tweaked extensively, yet still faced problems, particularly with Simplify3D failing to properly bridge the top unless the walls were made excessively thick. Undeterred, I redesigned the Secret Heart from scratch twice, and included the new OpenSCAD file. The main challenge with any design that features moving parts lies in the clearance tolerance between components as they are printed. If this tolerance is too small, nothing will move, whereas if it's too large, the entire device will be loose. To alleviate this issue, I've provided STL files for versions with varying clearance tolerances: 0.2mm, 0.3mm, 0.4mm, and 0.5mm. My TAZ 6 is currently using a 0.2mm tolerance. To save you the trouble of printing the entire device and discovering that you've selected the incorrect version, I've included test prints of key components: the main joint and the hinge for the top flap, each with clearance tolerances ranging from 0.2mm to 0.5mm. I recommend printing the main joint and verifying whether it turns smoothly; if not, you may need to employ a knife to separate the two parts slightly. Additionally, I've included an example featuring lettering, which can be easily created using the OpenSCAD file. Now it's your turn to have fun! P.S. (12th Feb 16:23) After multiple iterations and re-loading these files, I'm confident that you'll find them useful.
