Ball joint leveling feet (M5) / tilting adjustable foot

prusaprinters

<p>A leveling foot with a ball joint to tilt the base of the foot on sloped or uneven surfaces.<br>Four of these and a 20x100cm plywood sheet let me put plants upright on a 5° slanted outside windowsill.</p><p>The ball has a M5 thread, so that you can mount a bolt of your choice. 3D printing does not cope well with small threads (at least for me), so I recommend to finish the thread with a tap.</p><p>The bottom part consists of two models – the socket for the ball and a washer. The washer should be printed with a rubber-ish filament like TPU, so that it provides sufficient friction.</p><p>The uploaded openscad source file is parametrized, so you can change ball size / thread diameter / looses etc.</p><p><strong>Filament:</strong><br>I used PET-G for ball &amp; socket, but any filament should work. Consider temperature and UV resistance of the filament if you plan to copy my idea of leveling a windowsill. (Probably ASA would be better.)<br>Washer should go with TPU or other flexible to increase friction and prevent sliding down.</p><p><strong>Print settings:</strong><br>0.2mm layer and 0.5mm nozzle works fine. No supports needed.&nbsp;</p><p><strong>Post-printing:</strong><br>Check if the ball thread is not too tight, if it is, then tap it first.&nbsp;<br>Fasten the bolt of choice to the ball.<br>Press the washer in the socket and snap the socket on the ball.</p><p><i>For modelling the metric thread, I used the following library:</i><br><i>https://dkprojects.net/openscad-threads/</i></p>
