Rubber Band Elbow V1.0

thingiverse

I was developing a project that demanded a spring-loaded joint capable of swinging between 45° and 90°. As it happened, I failed to locate one on Thingiverse, so I decided to create my own from scratch. This homemade model relies on a small rubber band extracted from a pack found at the "Dollar Tree" stores in the United States. The blue parts were fabricated on an Ultimaker 2 using .2mm layer height, .8 shell, and .8 top/bottom settings at a print speed of 90mm/s. Remember to deactivate support material for optimal results. The orange pins served as temporary placeholders for more robust hardware like nuts and bolts. These pins were printed on a Tinkerine DittoPro with a resolution of 200 microns at an increased print speed of 80mm/s. Although the final product is fully operational, it's essential to note that it serves as a prototype for users to modify and incorporate into their own projects. Soon, demonstration videos will be released showcasing its capabilities, while future updated versions may become available. Post-printing adjustments are necessary to ensure smooth operation. To assemble the parts, wrap one end of the rubber band around the central bridge, just like in the second image. After that, loop the remaining rubber band segment around the corresponding hook on the other part. The last photograph displays the recommended orientation for both components.
