Earmuffs - Magnetic Belt Holder

Your hearing should never be taken for granted. If you already use earmuffs to protect your hearing, great!! This EDC device is for you! Whether you are at the range, in the workplace or in your workshop, you will appreciate this quick release, magnetic earmuff holder that goes with you, wherever you go!

Medical warning  
This device uses strong magnets and may not be suitable for certain medical devices. If you have concerns, please consult your doctor before using this product. 

How it works

This device lets you magnetically stow your earmuffs to your belt when not in use!! Cool right? You attach part A to your belt or simply place it in your pant pocket. Attach part B to the center headband of your earmuffs. Use two zip ties through the slots provided to secure it to the headband strap. (See attached photos.) The two strong magnets will secure your earmuffs until you need them. You may wish to add a piece of foam to the underside of part B for optimal comfort.

The Magnets 

Two magnets are required for this project. They are polarized. You may want to mark the polarity with a Sharpie. The magnets are super glued into a pocket in parts A & B. You must glue the orientation of the magnets correctly, otherwise they will repel each other. These are strong magnets!! Handle with care. (See link below.) https://www.mcmaster.com/product/5862K175

Cable Ties
2 req’d. 1.34 mm x 4.4 mm x 275 mm long. 

Part Orientation

You may be tempted to orient the parts differently but we recommend using the parts orientation shown in the g-code file. This is specifically for functional part strength. If you do not use a bed adhesive, you may want a brim for both parts. 

We use Layerneer Bed Weld exclusively on all our prints. “This is the way!!”
