Clutch-Style Mini Driver

Long story short (yada : yada : yada), this design takes up Highrise Workshop's (perhaps unintended) challenge to make a spring-clutch mini screwdriver without any additional hardware. Like a ratcheting driver, the spring-clutch allows you to back-rotate the driver without disengaging the bit. Just press in to drive, and then release the pressure slightly to freely back-rotate. Unlike a ratchet, it works both directions without needing a reversing mechanism, but it does take a little more deftness to use. Like the other drivers linked to above, this uses 4mm shank driver bits, up to 28mm long, and there is storage in the handle for up to 6 bits.This prints and assembles easily. Use 0.2mm layer thickness and 0.42mm perimeter lines to make sure all for the tolerances work out. All parts print without supports. The body prints on end and may tip without good bed adhesion. I've included models with and without little brim pads (don't use your slicer's brim feature) that you can use, depend
