Springy Printer Foot

prusaprinters

<p>There are many other good solutions on the net. I came to this solution because on the one hand i wanted to know how to print a spring without support and on the other hand i wanted to know if this problem could be designed with freecad. At my work I usually design with Solidworks.</p><p>The task of the springy printer foot is to absorb the kinetic energy that arises when printing the gyroid fill pattern. I use the foot on my 3D printer Prusa MK3S/S+ &amp; MMU2S. In order to use it on other printers, the spring force must be adjusted to the weight of the printer by changing the resilient cross section. The foot can be used on all printers with a 30x30 8th groove aluminum profile.</p><p>One DIN 912 M3x10 screw per foot is required for assembly. When using the slot nut with a threaded insert, a Ruthex RX-M3x5.7 insert is required. A soldering iron is then needed for assembly.</p><p>The photo with the foot is an earlier version that worked very well. The present construction improves the printing result. All parts do not require supports. Print - assemble - done. maybe this will help others with the same problem.</p><p>Information for printing is stored in the freecad files.</p>
