Description
A compact 3D-printed replacement keychain plug designed for the Marshall Jack Rack Keyholder.
This model replicates the look and functionality of the original 6.3 mm (1/4”) jack key plug, but in a more compact and practical design — easier to carry in your pocket while staying fully compatible with the original wall rack.
Perfect if you’ve lost one of your original plugs or want additional keychains for your home, studio, or friends.
Fully compatible with all Marshall Jack Rack II mounts and designed for a precise, snug fit.

The model comes in two handle patterns — differing only in the texture of the grip area (the part with the keyring hole):
Both versions are functionally identical and fully interchangeable.
Add a key ring or clip for easy attachment.
Print in black and silver for an authentic Marshall-style look.
