MagHub 10/22 Triple Drum Magazine Coupler

Description
The MagHub is a durable coupler that links three Ruger 10/22 barrel magazines into a single compact unit. The hub body press-fits into the magazine base, while a removable lid clamps the hubs together and is secured with a M6 × 35 mm socket-head cap screw and nut for a tight, rattle-free connection. Purpose-built for drum magazines, the MagHub keeps your mags organized and ready to swap.

Features

• Connects three Ruger 10/22 barrel magazines into one solid unit.
• Hub press-fits into the magazine base; lid clamps over hubs and fastens with M6 × 35 mm hardware.
• Reinforced geometry minimizes play between magazines.
• Print-optimized design—no supports required when printed flat.

Hardware (recommended)

• 1 × M6 × 35 mm socket-head cap screw (stainless steel preferred)
• 1 × M6 nut — nylock optional for vibration resistance

Assembly

1. Press each hub firmly into the magazine’s bottom recess until seated.
2. Align the three hubs and position the lid.
3. Install M6 × 35 mm screw through the lid and secure with M6 nut. Tighten until snug but do not overtighten.
4. Confirm all three mags are secure with no movement.

Notes
Designed and tested using OEM Ruger 10/22 10-round barrel magazines. Not affiliated with or endorsed by Ruger.

The ASA version has been slightly scaled larger than the PETG version to balance the shrinkage that ASA experiences when it cools.  

There is a small cylinder that prints with the lid.  It's just a support.  Pop it out and discard it.
