Remix of Gur Telem's Remix of danivbel's Snapmaker U1 Toolbox Tray.

I created this version with two objectives in mind:

1.   Store in the machine all the ancillary spares, lubricants and hotends that came with the Snapmaker.

2.   Design similar to the danivbel's Snapmaker U1 Toolbox Tray.

This tray will hold all of the remaining materials that aren't contained in the front mounted toolbox tray.  I've sized the tray so that it clears the bed when fully down (270mm).

Printed in PETG with 2 walls, 15% Gyroid infill.  If printing on the U1, I highly suggest using PLA as the support interface to get a nice clean under surface.

Use one of the screws from the front tray to mount in the back.
