<p>For a while wanted to have very light power bank mount for my Quest 2/Rift CV1 strap with option to quick swap batteries when needed without even taking off the headset.&nbsp;</p><p>Decided to use extremely power dense but very light Nitecore 5000mAh battery with included magnetic power bank attachment. The weight of the total set of printed part plus battery is only 106 grams! and without the attached battery its only a small fraction of that. The output power of the power bank is 1.38A which is similar to my other power banks I used.&nbsp;</p><p>For this to work you will need:</p><ul><li>1 x Nitecore MBP21 intelligent battery system kit</li><li>2 printed parts. See pictures for printing orientation suggestion as you will need to inset magnets.</li><li>3 x 20mm x 6mm x 1.5mm magnets</li><li>3 x M3 x 6mm countersunk/flat screws</li><li>3 x 3mm inserts ( and probably something to install them - soldering iron works great)</li><li>I also provided small printed template for easy drilling into head strap but that is option.</li></ul><p>Nitecore MBP21 set with NL2150HPI battery.</p><figure class="image image_resized" style="width:70.37%;"><img src="https://media.prusaprinters.org/media/prints/67324/rich_content/173c7d1a-53e8-4387-8205-c9ac3d99d398/img_20210519_133034.jpg#%7B%22uuid%22%3A%226fd81830-1885-4282-b199-4b7fdf21305d%22%2C%22w%22%3A4000%2C%22h%22%3A3000%7D"></figure><p>Battery with magnetic power bank attached.&nbsp;</p><figure class="image image_resized" style="width:69.7%;"><img src="https://media.prusaprinters.org/media/prints/67324/rich_content/c6e9edff-6c52-4cfa-8f14-9464dcd49e19/img_20210519_133322.jpg#%7B%22uuid%22%3A%22bd36a051-debf-4a09-9f21-0b008cc6f415%22%2C%22w%22%3A4000%2C%22h%22%3A3000%7D"></figure><p>Printed parts:</p><figure class="image image_resized" style="width:70.52%;"><img src="https://media.prusaprinters.org/media/prints/67324/rich_content/51d8dcbe-70e8-448a-b93e-d889d556c58b/img_20210519_133116.jpg#%7B%22uuid%22%3A%22486eaccb-cfef-4de6-9bad-2c960eda2990%22%2C%22w%22%3A4000%2C%22h%22%3A3000%7D"></figure><figure class="image image_resized" style="width:70.24%;"><img src="https://media.prusaprinters.org/media/prints/67324/rich_content/b6578445-5a8d-4529-8466-97e51d5cd205/img_20210519_133130.jpg#%7B%22uuid%22%3A%22a62d4c15-e7b5-44ea-a788-1999e1a132b0%22%2C%22w%22%3A4000%2C%22h%22%3A3000%7D"></figure><p>Installation instruction: Make sure you install first 3mm insert.
