Introduction: Eventorbot! Open Source DIY 3D Printer. Free Plans

Eventorbot! Open source 3D printer. Simple with less materials. Frame is made of a single 4' long, 2 1/2" square tube (16 gauge/1.5mm/.0598" thick, cost: less then $20.00). With this design there is less plastic parts, stronger structure, all wires are hidden, and a more appealing/finish look.
The unit is supposed to resemble a robotic arm with hydraulic tubes. It was designed for prints to be less affected by vibrations. With the 1 solid frame, any vibrations of any axis will cause the other axis to move with it. For example: If the X axis causes a slight
vibration/1mm movement to the right, the Z and Y axis will also move that 1mm to the right. This will result in a better print as everything will remain squared.

Parts list:

(1) 4' long, 2 1/2" metal square tube (this will be used for the main frame and the hot head mount). Diagram:

(3) Nema 17 stepper motor (at least 3 kg-cm 4 Wire). Specs for current motors used PDF:

(1) Geared stepper motor for extruder. (more info soon).

(12) 8mm linear bearings, model: LM8UU. Pic:

(4) 8mm ball bearing, model: 608Z. Pic:

(1) 9 1/2" long 5/16 threaded rod (for Z axis). Note: Most likely you will have some leftover after your 9 1/2" cut, use that piece to cut a 13mm long piece for:

(6) 10.5" long 8mm rod. Pic:

(1) Coupler 5mm to 8mm. Pic:

(1) Set of printed plastic parts (below ).

(optional) 1 set of printed decorative end caps (below).

(1) Set of screws. List:

(1) Sanguinololu 1.3a mother board with ramps. Ramps to be compatible to steppers (it should come with pin connectors and pins). Pic:

(1) MK7 drive gear (gear to drive the filament). Pic:

(1) 4 foot of XL timing belt. PDF:

(4) Push button momentary end stop switches. Pic:

(1) Bed. Aluminum or pexi-glass 8.5" x 11", 1/8" thick. (thickness does not have to be exact). Diagram:

(4) Springs for bed (this box should have all the springs you need for any circumstances:

(8) Rubber feet (bore holes need to be able to allow 10-32 screws) Pic:

(1) Roll of 1/4" black poly tubing. Cut to: (1)14" for hothead wires, (1)20" for filament feeder, (1)12" for bed to mother board tray connection. Pic:

(6) Air pneumatic tube 6mm push in connector fittings. (Total Size 21mm x 12mm/ 0.82" x 0.47"(L*W) Thread Diameter 9mm/ 0.354) Pic:

(1) 5.5 mm x 2.1mm DC power jack socket female panel mount connector. Pic: NOTE: If you choose to use a hotbed, upgrade this jack to something that can handle at least 13amps. As for your power source, you can use a Xbox 360 power brick. Xbox 360 power brick is 16amp and is more then enough to handle the power (under $20.00).

(1) Laptop charger 12 volt DC at least 5 amp. Pic:

(1) Hot end assembly (SKP file on diagram and how to build coming soon)
