All logic gates
thingiverse
Most recent versions of all logics are now available at https://www.thingiverse.com/thing:2829196, I highly recommend downloading directly from there. This comprehensive logic library features basic gates with clearly marked inputs, crafted using only links and pivot points as per the research outlined in the papers linked below. Currently, xor/xnor have not been included yet, but they will be uploaded once I complete them. For reference, please see the following documents: http://nextbigfuture.com/2016/04/molecular-mechanical-computer-design.html and http://www.imm.org/Reports/rep046.pdf. The scad file contains all previously uploaded components as well. Eventually, I aim to parameterize the file for animation purposes, but my current proficiency with open scad is still developing.
With this file you will be able to print All logic gates with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on All logic gates.
