Ratchet Bit Driver

prusaprinters

<p>A ratcheting driver for standard bits based on a circular ramp design. Press down lightly while turning the sleeve. In one direction the ramps engage and the shaft turns. In the other direction the ramps slip.</p><p>Print one sleeve and one shaft. Insert the shaft into the sleeve and it should click into place, with some free float to allow for the ratchet action. Now insert a bit into the shaft and use the driver.</p><p>There are two variants; one for tightening and one for loosening. One is just a mirror image of the other. Print one of each for a complete set. Be sure to keep track of which is which when inserting the shafts in the sleeves.</p><p>Print the shaft standing on the open end with the ramps upwards. Print the sleeves standing on the flat end with the open end upwards. No support needed for either.</p>
