Bits container

I saw this style bitcontainer for LTT bits. I wanted to make very own model for regular bits. Jar can also used for bit driver altought its not very handy. I made custom threads with three threads. Also wanted to learn how to make car tyre style outer shell. 

Wera bit holder also fits inside Jar.

I have made 6mmx1mm magnets slots for cap and under every bit slots. Also can be used without magnets.

Bottom and cap can be mounted 6mmx2mm thick magnets for stronger hold and feel. When closing caps or stacking jars it snap closes due to magnets.

Cap needs support for bottom, jar doesn't need any support.

I printed for 15%infill but added 25mm cylindricall modifier in center that  jar can be used as a bit driver.
