<p>Update 2022-09-19: There was an error in previous versions, please use _v4 FreeCAD file for your own experiments.</p><p>fischertechnik compatible housing for a 10x10mm electromagnet from <a href="https://de.aliexpress.com/item/32824124231.html">aliexpress</a> ("10*10mm Suction 0.3KG DC 5V/12V/24V Mini Nano solenoid electromagnet electric Lifting electro magnet strong holder cup DIY 12 v", you gotta love these aliexpress autotranslations!).</p><p>I used the 12V variant which nominally can lift 0.3 kg. It works fine with the ft-typical 9V to lift a metal ft marble, but gets a bit hot after a while.</p><p>Needs an additional M2 screw, ca. 7-8 mm, and two 9.5 mm "Bundhülsen". No soldering needed.</p><p>Print the larger part as provided with support touching buildplate, the smaller part prints fine without it.</p><p>Please consider leaving a "like" or posting your make as a token of appreciation for my work.</p><p>Find my other fischertechnik designs <a href="/juh/designs">here</a>.</p><p>Category: Construction Toys</p>
