Introduction: Building a 3D Printer Under 299$
Hello again, remember me?
I have published an instructable about how to make a 3d printer under 200$ - Tower Simple XL.
It's a low cost, full-featured 3D Printer, and the most important thing is, you don't need any 3Dprinted parts to build the 3D Printer. If I have a 3D printer,I don't have to look around how to build a 3D Printer...
If you are interested in creating a 3D Printer, you should have seen it. https://www.instructables.com/id/Building-a-3D-Prin...
And today I brought another more excellent project. Introduce my new machine - Vaster Mini3.
Salute to i3.
## Update v1.2.1 on step 23 ##
2015-09-22
Fan duct .stl file for Mini3 published on thingiverse: http://www.thingiverse.com/thing:1026997
Screws and bolts list added.
Fine-tune.

Step 1: Mini3 Version 1.0
This is the original version of Mini3 , I define it as the Version 1.0
I've done a lot of work to upgrade it, the latest Version of Mini3 is 1.2.1 , at 2015-09-22. and I'll show it in the following instructable.
In fact, all the versions are very similar.
What is highlighted in picture 2?

Don't waste any materials.

Step 2: Lasercut
Wood thickness 5 mm to 5.2 mm.
Step 3: Assemble the Main Body
Pay attention to the position of the board.
Version1.1 is the same principle.
Step 4: X Axis
Assemble the X axis.
## X-axis part list ##
Synchronizing wheel ; 2GT-20T ; 1
Synchronizing belt ; 2GT belt ; 600mm
Optic axis X- 225mm- Diameter 8mm ; 2
SK08 ; 4
SC8VUU ; 4
SC8UU ; 3
F625 ; 2
Leadscrew nut- T8 ; 2
NEMA17 ; 1
End Stop ; 1
####
Just push-fits SK08/ SCS8VUU/ SCS8UU/ F625/ NEMA17 together.
Step 5: Y Axis
Assemble the Y axis.
## Y-axis part list ##
Synchronizing wheel ; 2GT-20T ; 1
Synchronizing belt ; 2GT belt ; 500mm
Optic axis Y- 245mm- Diameter 8mm ; 2
SK08 ; 4
SC8UU ; 4
F625 ; 2
5mm-8mm Coupling ; 2
NEMA17 ; 3
End Stop ; 1
####
Just push-fits SK08/ SCS8UU/ F625/ NEMA17 and Coupling together.
Step 6: Assemble!
Attach X axis to main body with.
## Z-axis part list ##
Optic axis Z- 318mm- Diameter 8mm ; 2
Leadscrew - T8 -300mm ; 2
End Stop ; 1

No zip tie, get stronger.
And now we have successfully assembled a Mini3 V1.0
Mini3 was inspired by my desktop CNC.
I used to think of transforming the CNC to 3D Printer, But its printing speed is too slow. I think if we want to use the CNC to 3D Print, it must use ball bearings instead of leadscrew.
Step 7: Mini3 V1.0
Step 8: Mini3 V1.0
Step 9: Mini3 V1.1 , a New Beginning
After assembled Mini3 V1.0, I found its potential for upgrading and created an upgraded version.
In fact, V1.1 and V1.0 are exactly the same. Except a full version of the shell and some of the details of the adjustment.
Step 10: Mini3 Version 1.1
The latest Version of Mini3 is 1.2.1
2015-09-22
Step 11: Lasercut
Lasercut as usual.
Wood thickness 5 mm to 5.2 mm.

Step 12: Assemble the Main Body
Pay attention to the position of the board.
Step 13: Mini3 V1.1
Step 14: Electronic Parts
In this 3D Printer project, i continuing to use RAMP1.4, So it's the same with Tower Simple XL.
1. LCD 2004 *1
2. Arduino Mega 2560 *1
3. Ramps 1.4 *1
4. A4988 StepStick Stepper Motor Driver *4
5. 12V 40W Heating pipe *1
6. NTC Thermistor 100k
Step 15: Mini3 V1.2 , Instructables Edition
Mini3 V1.2 , instructables edition
## Update ##
Add 2004 LCD smart controler.
Add Mini3 extruder mount.
Fine tuning.

Step 17: Lasercut
Lasercut as V1.0 and V1.1.
Wood thickness 5 mm to 5.2 mm.
Step 18: Assemble
Assemble the main body
Remove parts from V1.1 to Version 1.2
Step 19: Mini3 V1.2
Step 20: Mini3 V1.2 Extruder Mount
I designed new lasercut parts to replace the old one.
Not only more firmly, but also cheaper and easy to get.
Step 21: Finished!
Finished and run some tests.
Step 22: Vaster Mini3
