About this 3D model
* 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 videos of the Miracube in action can be viewed here: https://www.youtube.com/watch?v=X2z2qGbcNx4&feature=youtu.be https://www.youtube.com/watch?v=f-N60tMJTgc&feature=youtu.be 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: http://www.thingiverse.com/thing:87250 The LCD is available at RepRapDiscount: http://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller and it work with Marlin firmware and probably with other ones. The Extruder is a remake of Greg`s Wade Universal Reloaded Edition ! http://www.thingiverse.com/thing:18619 The Bowden Bracket is derived from http://www.thingiverse.com/thing:126183 The 12V DC power supply cover is derived from http://www.thingiverse.com/thing:74562
