Valentines Day Heart with Moving Arrow

cults3d

This is a simple, yet charming gift for Valentine's Day. The design boasts a compact (approximately 32mm x 32mm at standard scale) heart with a free-moving arrow that glides effortlessly through its center. The arrow can slide back and forth about 6mm, making this unique print sure to impress someone special. Two versions of the design have been provided as STL files. One features a hole at the top, allowing you to thread a string or chain through it. The other is designed specifically for use as a key fob. To ensure the arrow moves smoothly and freely, do not scale down the print. Reducing the size will compromise the clearances between the arrow and heart, causing the arrow to fuse in place instead of sliding easily. With a good slicing app and a well-set-up machine equipped with effective bridging capabilities, the arrow should slide smoothly with only light pressure post-printing (a light lubricant can also help facilitate movement). It's essential to note that this print requires significant "bridging" that may be challenging for some machines and slicing apps. On a well-configured PLA machine with an effective filament fan, the arrow should release easily by applying gentle pressure against a hard surface. A small amount of silicone spray or another lubricant will help it slide smoothly. This design has been thoroughly tested on multiple machines without issue.
