Hypercube MK2

Coming from a Tech2C's Hypercube, this is an attempt to add the vitamins of a Prusa i3 MK2 to it.

First attempt was to use the dual-Z drive, to stabilize the print bed. Motors, rods and bearings from the MK2 are used. For this, all STLs are in the project.

The Hypercube is having an aluminium extrusion height of 500mm, I am optimizing the space to use as much of the drive length as possible.

I try to design the parts so they are not dependent on 4 points, but reduce to triangular where possible to improve stability.

Heatbed

In an attempt to reuse as much as possible, I thought about using the main rod construction from the Prusa as base for the heatbed. Maybe some day ..

You will need to print

• 4x z-rod-ext-v3.stl
• 2x z-motor-rod-mount.stl
• 2x z-carriage-mount-v2.stl
• 2x z-carriage-drive.stl

From the Prusa, take 6x bearings, 4 rods (the longer ones).

• 2x 290mm 2020 extrusion (like orig Hypercube)
• 2x 135mm 2020 extrusion (one more than Hypercube)

The bottom motor and rod mount fits the heatbed mount.

Update 20180223: added y-rod holder, never had as too much trust in the Tech2C, even when they did what they had to do. It is a strong fit just by the rods, let's check if that is sufficent or if it wears out over time.
