hi!
this is my version of hypercube with ideas take from original hypercube by Tech2c and by hypercube evolution made by Scott
work in progress!!!
I have some material here from another project and didn't want to buy other material so I made design to accommodate to my needs
build volume 300x300x300
the same as Scott I use 30x30 aluminium profile from Minitec that I buy here in my country as is more cheap than to buy from eBay
on Y axis i use 10mm chromed rod with 2 lm10uu each rod, on Z axis I use a 12mm chromed rod with 2 lm12uu on each rod
on X axis I use 8mm rod with 2 lm8uu for each rod
the only thing that I do not like in both designs is the xy stepper motors position so I made some changes to use the motor in the bottom side of the printer and that way I gain some extra room for xy axis because my aluminium profile that I have laying around was cut shorter than Scott used in his build and I want a total printing volume 300x300...
work in progress
YOU WILL NEED TO PRINT:
bed.STL x 2
bed_lead_screw.STL x 2
X_10mm_rod_clamping_rework.STL x 3
z_axis_top_plate_rework.STL x 2
XY_lm10uu_mounting.STL x 2
XY_back_idler.STL x 2(one is mirror of other)
XY_lm10uu_clamp.STL x 2
z_axis_bottom_plate_rework.STL x 2
xy rod sistem for bottom motors.STL x 2(one is mirror of other)
idler_front.STL x 2(one is mirror of other)
z_axis_top_plate_nut_holder_25mm.STL x 8
z_axis_top_plate_nut_holder_45mm.STL x 4
All other parts that is not set here you will have to print only one of each
in progress: xy motor mounts and z axis one motor for dual lead screw(im waiting of my closed loop belts to arrive)
list of materials:

3030 ALUMINIUM PROFILES FOR THE FRAME

-4 x 580mm round profiles(feet) you can use normal profile as the rest of the build
-10 x 400mm profiles for X and Y
-2 x 100mm profile(for Z axis back side bottom)
-2 x 80mm profile(for Z axis front side bottom)
-1 x 240mm profile (front bottom fo the printer where the "xy rod sistem for bottom motors.STL" will mount )
---this build uses hidden corners for mounting the 3030 aluminium frame together!---
FOR BED also used 3030
-2 x 400mm
-2 x 150mm(because of the shrinkage of plastic I had to file 1mm down from this 2 profiles for all things work perfectly...)
Currently the parts for z axis linear bearings mount are not uploaded...im thinking to change a few small things...

RODS AND LINEAR BEARINGS:

Z axis 4 x 12mm hardened steel rods with 390mm + 8 LM12UU
Y axis 2 x 10mm hardened steel rods with 400mm + 4 LM10UU
X axis 2 x 8mm hardened steel rods with 395mm + 4 LM8UU
also need 2 more rods 8mm in diameter with 495mm(you can use normal steel rods as it will be only for driving the xy because of the motors are in the bottom)

BELTS ,PULLEY AND IDLERS:

6m of gt2 with 2mm pitch belts
2 x 200mm closed loop belts(it is 100mm perimeter)
6 x 20tooth idler pulley with 3mm inside
2 x 20tooth idler pulley with 3mm inside(this ones is no tooth)
6 x 20tooth pulley with 8mm inside diameter
2 x 20tooth pulley with 8mm inside diameter

BEARINGS:

4 x 608zz berings (22x8x7)
12 x 688z berings (16x8x5)
m3 and m5 screws with different size
m3 and m5 nuts
I WILL UPDATE AS SOON AS RECEIVE LAST ORDERED PARTS NEEDED
