Anycubic I3 Mega tool storage

This is a screwless version of the [Anycubic i3 Mega Tool Rig by mjuddi](https://www.thingiverse.com/thing:2793693).
It's also for the right side corner, not the left one.

This is a v2.
I have :
- reworked the clips to fit perfectly and firmly
- added a bar to "encircle" the screws
- created a side insert for the tweezers
- moved some placements.

Once printed and got rid of the supports, install it from the back side towards the front.

You also have the Cura project now.

Enjoy !
