Bit Holder For Williams WRS-1 Ratcheting Screwdriver

A simple yet functional bit storage solution for the Williams WRS-1 Ratcheting Screwdriver. It may also fit certain Snap-on ratcheting screwdrivers due to them being similar in design.

• Holds 6 standard 1/4 inch screwdriver bits and fits snugly into the handle.
• Easy to Print - No support needed and takes less than an hour
• Stops the bits from rattling around inside the driver!

A few test prints and tweaks may be needed to get the bits to fit properly inside the holder. I designed the model with a +0.5mm margin of error to account for expansion or inconsistent layers, and while this worked well in testing, your mileage may vary. If the bits don't fit, make sure that your printer is not over/under extruding and your bed is level. You can also tweak wall/perimeter thickness in your slicer to make the bit slots bigger/smaller. The part should be very close to 18mm in length, width, and height.

*The included Gcode file is sliced in Cura for an Ender 3 Pro using Hatchbox PLA. This file produced the part you can see in the images above, and can be used to as a baseline to determine what changes need to be made to your print settings in order to get a part with good tolerances.

Happy printing! (and ratcheting!)
