prusaprinters

<p>This little gizmo holds a miniature pushbutton switch (see photos) and has magnets on the bottom to enable it to be held firmly on steel/iron metal surfaces.</p> <p>The pushbutton switch used is designed to be panel mounted in a 1/4" (7mm) hole.</p> <p>The magnets are 9.5mm diameter and 2.5mm thick.</p> <p>To use this print, simply push the magnets into the bottom recesses (they are held by friction) and mount the switch in the central hole.</p> <p>The OnShape 3D CAD files for this :</p> <p><a href="https://cad.onshape.com/documents/e4e2f7da5bc2761735233f1c/w/5b91d6984de9258ba072c004/e/2514c5801cd50c83573f598d">https://cad.onshape.com/documents/e4e2f7da5bc2761735233f1c/w/5b91d6984de9258ba072c004/e/2514c5801cd50c83573f598d</a></p> <h3>Print instructions</h3><p>Print in PLA using the 3mf file provided; otherwise :</p> <ul> <li>perimeters = 3</li> <li>15% rectilinear infill</li> <li>print upside down</li> </ul> <p>The easiest way to insert the magnets is to partially insert them into the bottom recess and then push the holder down firmly on a flat surface. This is easier if you insert the magnets before mounting the (pre-wired) switch.</p>
