Systainer drawer holder

This is a remix from [3384547](https://www.thingiverse.com/thing:3384547). In this original thing all components are in one STL file (the two jigs are also in one file). And some objects where not positioned at zero and floating in space.

I fixed that in this remix: all the parts are now in separate files and I set everything is at zero. Importing of the files into your favorite slicer should now be easier.

###What to print

- 2x holder_back
- 1x holder_front_left
- 1x holder_front_right

Additional:
- 1x jig_left
- 1x jig_right

See original text how to use the jigs.


###Original text

This system transforms systainers into drawers by keeping them on sliding boards.

I used total exit type slides of 350mm and borads are 400mmx305mm.

Jigs allow to place the parts on the boards at the right position to screw them on. (works only on 400x305mm boards!)
