This is a simple design that originally came from following https://www.youtube.com/watch?v=VvpQu2rsH3A very early on in my learning. The tutorial gave me all of the tools needed to design the V1 of this. Following the original tutorial stage I made some modifications to this design in order to add a spot for my Stanley knife to go as I find it is used nearly as often as my screwdrivers which in this case is a mixed bunch. V1.1 of this design does away with some design issues in V1.0 and chamfers around the bottom and top to allow for easier ejection of part and the screwdrivers to have a sort of path to slide along into the spot for them. This is a very basic design so the step file will also be available where possible. I have been using the original of this for 12 months now and I’ve also made some changes around the holes so as to get a better fit with 8G screws.
