3D Printer's Jack

<p>This 3d Printer's Jack was inspired by the Machinist's Jack build by Inheritance Machining on YouTube. It features two separate thread pitches to allow for a rapid movement and a fine movement. This model was designed and printed with resin printing in mind and as such has very fine details that an FDM printer may not be able to achieve.</p><p>This 3d Printer's Jack was printed on an AnyCubic Mono 4k all at once. The models were attached to the build plate directly with no supports.</p><p>I used GAN Lube #2 (Speed Cube [Rubix] Lube) on the threads to give it a silky smooth operation. The final print was sanded with 220 grit then 320 grit and finally 600 grit sand paper to smooth the edges and give a better finish. The threads were not sanded, only lubed.&nbsp;</p>
