Ellipse-Heart

thingiverse

Rotate about the central axle to transform between a heart and an ellipse with my first print-in-place "mechanism". Think twice before printing this for Valentine's Day, unless you're sure she's as geeky as you. Print Settings Printer Brand: Printrbot Printer: Simple Black Rafts: No Supports: No Resolution: 0.2 Infill: 15% is fine Notes: Thick walls to ensure axle is solid.... 4 shells, 4 solid layers. Post-Printing Break the axle away from one or the other half with a gentle twist of the two halves. There's no need to break it away from the other half unless you're OCD. Separate the parts by sliding a knife down between the two body halves and at either end of the axle. Don't cut deeply at the axle in case you weaken or break it. How I Designed This I based my design on one found on the Internet (e.g. http://www.cutoutfoldup.com/1609-ellipse-to-heart). My design is available at OnShape.com... search Public projects for "Ellipse-Heart". The variable "tol" can be used to adjust the tolerance between parts in case you want to try printing a more accurate or easier to separate version. Mine is set at 1mm. You can also adjust the thickness of the model. Mine is set to 10mm which results in a 3mm axle if the tolerance is 1mm.
