Dewalt multi battery holder (with drill mounts)

I wanted to organize my batteries in an easy way, without measuring the correct distance for each battery.

I came up with this idea, so that the batteries are all at an equal distance and easy to mount. If the first holder is horizontal, the rest will be the same. The spacers are there if you want to use the drill/grinder mounts. This way there is enough room between the various tools to easily place and get them. See pictures. 

This way, you can make as many holders as you like, or add in the future. 

Along the way, i tried to design a mount for my drills that would fit in the battery holder. I printed these with 20% infill, 3 walls and 0.2mm layer height. The mounts are printed in PETG carbon fiber, the battery holders in plain PETG.

The battery holder and spacer don't need any support when printed upright, the holders have support as seen in the picture. Print them as shown, so big flat side down.

The mounts for the drills can be inserted anywhere, as you can see in the pictures, you only need the spacers for that. 

The holder for the power-drill and the angle grinder are the same, only the holder for the normal drill is a bit longer, otherwise it won't fit all the way in. 

If your printer is set up correctly, the spacers have a firm fit to the holders, so they won't fall off when inserted to each other.

Hope you like it, if you have ideas for improvement, let me know and i see what i can do.
