Generic Magnetic Hose Adapter

This is a generic hose adapter meant to provide a flexible hose attachment method. My intent is to have a “universal” hose attachment that I can use with my printers as necessary. My original design is only for the Bambu X1C/P1S printers and so I expanded upon the idea. I've needed a venting solution for my resin printer and this allows me to use my existing solution between my printers.

If you are already using or would like to use my X1C/P1S adapter, the parts work together. The base is what's mostly different between these designs. If you plan on using this along with my previous adapter, verify magnet polarity so that the parts can attach correctly. You can find my X1C/P1S adapter at https://makerworld.com/en/models/136548#profileId-148624.

There are two sets of 3D printed parts, one for 3 inch hoses and one for 4 inch hoses. The printed parts are as follows:

• Base - Provides the attachment method to your part for the hose to attach to and can be mounted using either M3 hardware or #6 wood screws.
• Base back plate - A back plate for the base with m3 nut retainers to allow for easier installation. NOT required if using wood screws.
• Base cover - Simple cover that fits over the base
• Hose adapter - Allows vent hose to attach to the base
• Hose cover - Simple cover that fits over the hose adapter
• Magnet test - Used to test fit magnets before printing larger parts

The base and hose adapter utilize magnets as the attachment method, allowing for quick and easy connection of the hose to the base or moving between devices. The magnets are 10x2mm cylinder neodymium magnets. I made the parts so that the magnets could be press/friction fit into the holes. The hose adapter magnet holes are a bit deeper to account for the loss of depth due to bridging. You could glue in the magnets of necessary. The magnets I sourced from Amazon weren't exactly as advertised, but measured 10x1.67mm which I designed the holes to fit.

The design is meant to have the magnets press fit into the holes, so there's some expectation that they are a bit tight. Since the tolerances are tight and there can be variations in the printed result, not to mention any size variances with the magnets, I've included a test print. I suggest printing out the magnet test provided in the print profile or the Magnet_fit_test.stl file to test fit magnets before printing out the larger parts so you don't waste the filament. Make sure to test with the filament you plan on using for your final part. If you find that the magnets aren't fitting as expected, you can tweak your X-Y hole compensation in Bambu Studio/Orca Slicer. Make small adjustments up or down as required.
