Life Tracker (0-999)

thingiverse

A (0-999) health/score tracker designed specifically for gaming enthusiasts. Engineered to be compact, measuring 54mm in diameter and just 10mm thick, this device is easy to use. It can track two stats ranging from 0 to 9 or one stat up to 99 using the top fixed plate's arrow. Numbers between 100 and 999 are easily determined by utilizing the hundreds place as your arrow. The tracker features internal compliant springs that keep the number wheels securely in place, ensuring they remain stable even if bumped. UPDATE #1: New "LT" stl files have been created with a chamfered base to address the elephant's foot issue at the base of parts, resulting in improved tolerances and eliminating the need for rafting. The column width has also been slightly increased to create a press fit with components. With correct printer settings, glue is no longer required. UPDATE #2: The numbers on the tracker are now rotated so they can be read along the side, and the stationary ring has been smoothed out to prevent confusion with the movable ring. The base has been enlarged in thickness and width for a secure hand hold. Print Settings: Printer: Wanhao i3 Rafts: No Supports: No Resolution: 0.1-0.2mm Infill: 20% Notes: Print 1x Face Plate, 1x Large Ring, 1x Small Ring, 2x Springs, and 1x Base. Rafts may not be necessary but help ensure the spring doesn't fuse. Post-Printing: Post-Processing: Updated: Components should press fit together after printing and removal of support (I print without brim or raft on new stl files.) OLD: The assembly is designed to stay together with glue, but since the springs and cover are stationary, epoxy can be used to cement the assembly. I recommend using a sharpie or modeling paint to make lettering a separate color for better readability. It may also be possible to use a laser cutter to create the components from alternative materials. Evolution of Spring and Ratchet Mechanism: After testing the tracker with friends, it became clear that everyone held onto the bottom ring and attempted to rotate the stationary ring. This caused the top rings to turn together, making the counter difficult to use. Instead of providing a tutorial on how to use it as intended, I redesigned the form to match the function. The redesign includes removing texture from the top plate so it won't be tempting to turn, making the base plate thicker and wider for a secure hand hold, and turning the numbers sideways for easier reading. Future Improvements: In coming months, I plan to tweak the design to allow all visible components to be laser cut from alternative materials. This would also reduce manufacture time to about 15-30 minutes as the springs are the only part that needs the flexibility of the printer. Completed: I am looking into making the whole assembly press fit to remove the need for glue and allow for replacing springs if they end up breaking after extensive use.
