E27 lightbulb storage holder

I had a lot of spare lighbulbs and I didn't know how to store them properly and safely. So, I designed this holder where I can just screw them securely into place, maintaining a separation between them.

The thread is standard so it holds them really well and you can even turn it upside down and they won't fall.

If the bulbs are too big, they may not fit properly, I include Fusion 360 and STEP files so that you can edit the separation if needed.
