Neo-Walk Acrylic Cane LED insert

LED insert for Neo-Walk acrylic "bubble" cane: https://www.neo-walk.com/product/clear-bubbles/ Uses four small 5 mm color changing LEDs, two LR44 button batteries, eight M3 grub (set) screws and a 7 mm square push-on/push-off switch. Can use small springs or M3 screws at the ends of the battery holder to secure the wires. Note that there isn't a current limiting resistor in the circuit since the batteries do not produce enough current to overdrive the LEDs, but feel free to add a small resistor based on the characteristics of the diodes you decide to use. Supports may be needed for the LED holder with ring if your printer doesn't bridge well. 1-22-2023: Created new files for the LED holder. Initial design had grub/set screw holes aligned with LED pins, which could cause problems with longer grub/set screws. New versions added with holes rotated 45 degrees to avoid interference with LED leads. 1-22-2023: Also made a version of the LED holders using a separate ring that can be either attached/glued to the LED holder or inserted into the cane opening to offset the LEDs so they don't contact the solid acrylic. This help decrease the risk of damage to the LEDs. 3-29-2023: Modified main body to use grub screws to hold the switch in place for easier removal if needed.
