Hypercube DUAL Leadscrews

I designed this to use a dual leadscrew design with stock hypercube dimensions, but they should also work for bigger dimesions, if your bed assembly is compatible.
You might need 3 addtional aluminium extrusions:

2 additonal y pieces to mount the top-rod holders (303mm with stock dimensions)
1 bed piece to make the bed assembly symmetrical (135mm with stock dimensions)

i connected the rod and motor holders to make it much easier to allign the stock parts.
The parts are designed for 8mm
