MiraCube V1.0

• 05/11/2014 Finally added a BOM.cvs
• 09/10/2014 Added a new version. V1.5 With some important modification.
  I positioned the Z-axis motor outside the structure, the only 3d piece
  changed is the 17_Z_Screw_Driver.stl, it must be replaced by the 40_Z_Screw_DriverV1.5.stl
  You can see a new project on tinkercad her:
  https://www.tinkercad.com/things/bhpW4FNh38z-miracube-with-1-hotend-v15
• 09/10/2014 Added entire set of x carriage for 1 hot end only

• 37_x-carriage_1_hot_end.stl
• 38_X_car_Belt_1_hotend.stl
• 39_X_car_fan_1_hotend.stl
  In this case you can print only 1 exstrusion set.

 

• 05/09/2014 Added a 40mm fan duct for PLA printing

• 36_x_carriage_fan_duct.stl

A Corexy 3D printer.
This thing was made with Tinkercad. Edit it online
https://www.tinkercad.com/things/f7uonb7lb4N-miracube-v10
From the above tinkercad link you can build simply the MiraCube. In the 3d tinkercad project you can compute all the measure of aluminium extrusion profile.
I used two type of brico aluminium extrusion profile

• 10mmx10mm
• 20mmx10mm
  Yuo can rescale the entire printer on axis Y and Z. For the resacaling on the axe X You must reengineer the heatbed support mount.
  In the tinkercad link below you can see a rescaled MiraCube with a volume of 20x40x30
  https://www.tinkercad.com/things/fpE4DgV8KrO-miracube-20x40x30
  For the X Y and Z sliders I used 8mm smooth rods (you can get the lenght from thinkercad project) and a LM8UU linear bearing.
  For the kinematic motion I used 4mm inner hole ball bearing and a GT2 belt.

 
If you like the printer can write a comment or leave a feedback.
Thank you.
 
Una satmpante con cinematica Core XY
 
Questa stampante è stata creata a partire dal progetto pubblico che puoi trovare su Tinkercad al link:
https://www.tinkercad.com/things/f7uonb7lb4N-miracube-v10
A partire dal progetto Tinkercad puoi costruire la Miracube con estrama facilità. Nel progetto puoi calcolare e ricavare ogni singola misura di ciascun pezzo in alluminio.
Per la stampante in foto ho utilizzato due tipi di estrusi in alluminio facilmenti reperibili in un qualsiasi negozio brico (Leroy & Marlin, Brico, Obi, etc.):

• barre da 10mm x 10mm
• barre da 20mm x 10mm
  Inoltre, sempre dal progetto Tinkercad puoi scalare l'intera struttura della stampante sia sull'asse Y che su quello Z. Per l'asse X andrebbe reingegnerizzato il supporto per il piatto riscaldato.
  Nel link di seguito puoi trovare già un progetto scalato con dimensioni di stampa 20x40x30
  https://www.tinkercad.com/things/fpE4DgV8KrO-miracube-20x40x30
  Per gli slider X, Y e Z ho utilizzato delle barre rettificate da 8mm e dei cuscinetti lineari del tipo LM8UU. Anche in questo caso puoi ricavare la lunghezza delle barre dal progetto Tinkercad.
  Come cuscinetti a sfera per la Cinematica XY ho utilizzato dei cuscinetti con foro interno da 4mm ed una cinghia dentata GT2.

 
Se ti piace la stampante scrivi un commento o lascia un feedback.
Grazie

Soon I will enclose a BOM and a guide with the construction steps

The GLCD cover design is a little mod of wersy's one:

The LCD is available at RepRapDiscount:

and it work with Marlin firmware and probably with other ones.
The Extruder is a remake of Greg`s Wade Universal Reloaded Edition !
