One has 8 magnets per side while other has 6 magents. It's not very strong as it can fall off easily if touched or knocked down. But that only happens while carrying a bike or getting on/off it. It never fell off while cycling. I still use the velcro that attaches to the front.</p><p>Bag has a slot for hanging. 2 pieces are mounted on it and has some magents while other piece is mounted on the tube with a zip tie and also has some magnets.</p><p>Before printing measure your frame size and enter values into the spreadsheet.<br>Depending on the frame size it varies how many magnets you can fit in. Adjust the sketch if you want to have more magnets.</p><h4>BOM</h4><figure class="image"><img src="https://media.prusaprinters.org/media/prints/76705/rich_content/49b3f96f-742e-43e4-8b20-47433580e6bb/dsc_7548.jpg#%7B%22uuid%22%3A%220984b691-c65c-41ba-80c7-2153cbb02dd8%22%2C%22w%22%3A6000%2C%22h%22%3A4000%7D"></figure><h5>For single set</h5><p>8x Magents 8x3<br>1x zip tie<br>3x 3D printed pieces<br>4x M2 x 6 Self-tapping screws</p><h4>Assembly</h4><p><strong>Measure frame update values in the spreadsheet</strong></p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/76705/rich_content/103a7ed7-6946-4682-9d9c-f0ae226cbff0/spreadsheet.png#%7B%22uuid%22%3A%22d91c1133-744d-429b-bbe1-c4441bb4ab8f%22%2C%22w%22%3A690%2C%22h%22%3A467%7D"></figure><p>&nbsp;</p><p><strong>Update Frame width and height.
