🧪 Experimental Feature: Dual-Side Cover Generator

An experimental generator is available for creating a dual-sided key holder. This version allows keys to be added on both sides of the holder, effectively doubling capacity in the same footprint.

⚠️ Note: This design relies entirely on two side shaft pegs for integrity. Durability has not been tested. So adding glue is recommended.
