KipBoy - Key Holder

thingiverse

Create a batch of thin spacers with a hint of post-apocalyptic flair. Print out a few of each, setting them between the keys like tiny sentinels. The spacers with flanges are designed to secure keys with larger holes, a mere 3-4 mm in diameter. Use them to pin down the keys, preventing them from wobbling about and compromising the keyboard's integrity.
