This rack holds all 8 drivers, in handle-size order from left-to-right. The slot is just a teense tight for the #3 Phillips-head driver. Would redo this if I could. Maybe your slicer can open it up just a little. 1mm should do.
Note: You'll NEED a wall or a board or something solid behind the handles on the rack, or they'll tilt over and the blades will come out the slots when you bump or tilt your workbench or whatever. (Found this out while hand-holding it just after printing). The 2x4 it's mounted on here (part of my bench) works fine for that.
I printed in black PETG on a Bambulabs P1S, diagonally to fit the print volume. Used .20mm Standard. Seems to work great.
The screws I'm using to land it into pine 2x4 are 2-1/2in construction screws. You will need drywall anchors and some LONG screws (2 in before you get to the anchoring threads) to anchor it into a hollow wall.
