80mm spindle dust shoe with magnetic connection (100mm hoose).

thingiverse

This is a dust shoe for an 80mm spindle, crafted with minimal dimensions in mind. It relies on 16 strategically placed magnets (10 x 3 mm) and two standard pins measuring 5mm in length. To ensure a secure fit, the magnets require a firm push into their respective pockets, followed by a strong adhesive bond. A light sanding of one side of each magnet enhances grip within these pockets, which are carefully designed to be 1mm deeper, allowing for the use of double-sided adhesive tape. Crucially, attention must be paid to the orientation of the magnets, as they are designed to attract their counterparts on the opposite side. Furthermore, a 5mm groove has been incorporated into the design to accommodate a brush strip, which necessitates a strong bonding agent or small radial screws for secure installation.
