Keychain Holder Designed to Not Move

Keychain Holder Designed to Stay Put Device Description and Problem Keychain Holder Solves A keychain holder is a device that's typically hung on the wall, with hooks used to hang keychains. I have one mounted inside my bathroom, held up by a string. The problem is that it often falls over into my sink counter due to its insecure attachment. Additionally, the hooks are poorly designed, failing to hold my keychains securely. I recently created a new keychain holder in lab using 3D printing technology. This device costs just $1.97 and can be printed in under seven hours using high-quality settings. Given that I paid around seven dollars for my current keychain holder, it makes sense to print a replacement at this price point. My redesigned keychain holder boasts slimmer and sleeker dimensions than the one I currently use. This design not only improves aesthetics but also helps prevent wear and tear on the surface. To improve stability, I increased the frame size of the new keychain holder so that tacks can be securely placed in the upper inside edges to prevent movement. Printing Details To account for parts that extrude out during printing, I included supports to prevent misshaping or warping. I also used fillets and chamfers on all sharp edges to enhance printing quality and add style with San Jose State University logos. Additionally, a raft was added at the bottom surface of the part to ensure secure detachment during printing. When designing the file in Fusion 360, I created dimensions in inches for my STL file and converted them to millimeters for use in Ideamaker. The design is optimized for the Raised3D N2 plus FFF printer used in class. It's intended for normal room temperature conditions in a typical household bathroom, using standard fill levels and shape settings specified in high-quality printing settings.
