We printed some little sliders to make our embroidered motors pull with more force. The tradeoff is a shorter travel distance. It took about 8 minutes to assemble the three sliders by hand, a process we aim to speed up with automation in an upcoming project. Below you can see two compound sliders in action. Each slider doubles the force and cuts the travel distance in half.
