Decided to remix this idea i originally found on thingiverse to more suit my needs, and to reenforce the original design where it was lacking in strength before.

Was looking for a way to stack my spools for my mmu2.0 to be able to save on some workbench real estate and i found this design here (www.thingiverse.com/thing:2719998) and desided to mix it up to suit my needs more.

Had to make things thicker and more sturdy by adding in supports where it was weak and adding additional parts to help with the strength.

Thing is still a work in progress but is fully functional and sturdy as it is.

Will take some time to print as its parts are large. Printed on a combo of Mk3 unit and a Mk2.5 unit.

I made the original holes bigger to accept M3 screws in all mounting locations.

Can check out my youtube video here as well on this thing:

I have added the .F3D and the .STEP files for those that want to make this design more to their likeing
