Two Component Mastic Storage Tray with tools v3

Note: Do not print. I have few things to change. Contact me if you want beta upgrade

needed compact way to store in my car two component mastic (newer heard of that name - it is 2 component glue that hardens quickly into a solid), and have it along with thee tools on the go.

This is my solution. This is third iteration. Handle was biggest problem. Tell me if you think I can improve it.

I printed it in PETG so the glue in not sticking to it, and it will be on the sun etc. Printed with 0,4 nozzle mostly with .3 layer height. There are supports. 3mf files are prepared for printing. 

It consists of main body, handle, that slides and slides into main body. Tray for miking components, and spatulas for mixing and applying to surfaces. After drying You should just bend the plastic and (at least mine) will just fall off, and it is ready for next batch. 

There are 2 spatulas - 30 mm and 60 mm wide. If you need different dimension, notify me. 

For opening the can, there are 2 slots, one 8mm and other 10 mm wide for an old crew driver or custom opening tool. This part printed makes no sense. 

Any suggestion is appreciated.
