This is a holder for two iFixit 4mm Precision Drivers, which will give you a 1u bin to securely store your drivers while still allowing them to be easily grabbed with one hand. I designed it to sit in front of the iFixit Manta driver kit, with Petrepa or Magmin's holders in mind. The drivers are held with the bit-side up so that you can easily load a bit with one hand before grabbing the driver. Also, you won't have to worry about removing the bit before placing the driver back, making it easy to put it back in-between frequent uses during a project. Never lose your driver on your desk again!

If you have an iFixit Manta, check out my 1u Manta Driver Holder, as it's the perfect compliment to this holder.

I used the wonderful Gridfinity Refined base for this holder, which allows for easy magnet insertion and hard-mounting, if you find you need this to be super securely held down. I've included the Fusion source file as well, if you'd prefer to swap out the base for a different style. Please upload a remix if you do, so other people can benefit as well =). 

The model pictured was printed in Inland Translucent Grey PETG+, with 0.3mm layer height, 3 perimeters and 50% Lightning infill, which makes it almost entirely hollow. It should not need supports, the base is designed to be printed without them.
