A two-part drill holder design for the smaller 12v and 10.8v drills/impact drivers.

Disclaimer: This is intended and designed as a temporary storage solution during the work being undertaken and NOT as a permanent storage solution. 
The design can easily support the weight of the impact drivers(and heavier 10.8V Makita impact wrench I also have), but care must be taken to ensure the end of the drill/drivers is firmly in place as sometimes they can fall out.
Again, this is designed as a more temporary storage solution and not a permanent, more secure one. 

Main body:

The main body is easily removable from the backplate to allow for more flexibility when working with minimal space. A dovetail is used to keep the main body securely attached to the back plate and comfortably bare the weight of the drill or driver. 

Drills/drivers are stored 'upside down' compared to most other designs to allow for one handed easy access and storage, as well as allowing the drills/drivers to be stored with long extensions still in place.

Designed to comfortably fit Makita 10.8V designs as well as older Milwaukee 12V.
May not fit newer Milwaukee versions or other brands.
(The ones pictured are the only ones I own and can test). 

Backplate:

The back plate has 3 different holes to allow for different spacing needs. I recommend using the centre hole or the two side holes, depending on your setup. 
Designed to use M5 Cap Head bolts, with the holes counterbored to not interfere with the dovetail joint. 
The centre hole is around 2.3mm to the back face; the two side holes are around 9.8mm to the back face.

Designed to be attached to a cable tray present on my workbench, the different holes can accommodate the spacing of the holes in the cable tray, but also to match whatever works best in your situation. 

Print settings:

I printed these in regular PLA and they've held up great for months. PETG might hold up better should you need. 
The tolerances were designed towards my Centauri Carbon (around 0.1-0.15mm), so the dovetail may be snug or tight for other printers with a larger tolerance.

Nozzle: 0.4mm
Layer height: 0.2mm
Walls: 6
Infill: 30% Tri-hex
Top/Bottom layers: 6 & 5 (Not sure this many is needed) 
Supports: None needed (The holes are tear dropped for better printing)
Orientation: Print as is

Final Disclaimer:

I designed this for my specific setup at work. I use it to keep my drill/drivers off the workbench, giving me more space and quicker access to them. It's great for grabbing them one handed quickly, and being able to store it all away and not take up space if I'm not using them for the job I'm on at that time. 
They're fairly secure and don't tend to fall out even when I'm hammering away on the bench, but they can fall out if I don't get the ends in right. With a rubber mat on my bench and the small amount of space below where they are(plus the usual pile of rags underneath them) this doesn't matter to me, but if used with a large gap above a floor or harder surface, the drills/drivers could fall out and get damaged so take care. 
Again, this is more of a quick access temporary storage than anything more secure and permanent than most designs you find out there. 

Also I designed this on Plasticity before I moved over and learnt Fusion, so I don't have access to easily modify the design. I might should I find the need in the future but am unlikely to be able to make edits or provide different file options such as .step (as I usually try to do).
