Summary

Hi!

This is based on the classicDrawing board/Electronic plotter

Simply by rotating the knobs of the X and Y axes, you can draw the creative patterns in your mind as you wish.

It's easy to use, whether with a marker or a pen, and the results are excellent.
The drawing area is approximately 15×10 centimeters.
The X-axis is responsible for driving the entire paper to move horizontally. This design inspiration comes from the Y-axis structure of the Prusa printer - the entire printing platform can move synchronously along the Y-axis direction.

The whole machine is composed of many parts, and most of the parts can be perfectly molded without the need for a support structure

I sorted all the parts into six files according to the printing parameters and assembly sequence of each component.

Please find enclosed a copy of the documentA PDF document containing assembly instructions and practical tips。
And at the same time, provide oneA ZIP compressed package containing all STL files, so that you can easily download the model files of each component one by one.
In addition, the original design files in the 123D Design format are also thoughtfully provided.

Please make sure to check the print settings carefully.

Finally, if my English expression is not fluent enough, please bear with me—I am from Spain, and my English writing skills are quite limited, so there might be some minor grammatical errors.

Update!!Now,"all_parts_separated_update.zip" ZIP compression packageThe STL files of all parts have been integrated in the Chinese version

Updated on September 18, 2016: YouTube video——The ScienceMadeFunner channel has released a wonderful video.https://www.youtube.com/watch?v=JM1SavDy5Rc)，it shows in detail the printing, assembly, and actual use process of MicroSketch. Go take a look now!

You might as well take a look at the one that has been carefully renovated by PowerScissor.Derivative works：https://www.thingiverse.com/thing:2696231

Wish you a great time!

Printers:

BQ Prusa i3 Hephestos
 

Note:
 

The test has been conducted using PLA material.

If you encounter problems with poor adhesion, it is only then that I recommend enabling the base support. In fact, I have never used the base support and was still able to print successfully, with equally excellent results.

Important notice:Please make sure to adjust the "flow value" in the printing software to ensure that all components can still fit perfectly after being lightly polished.
It is recommended to use something similar.The tool of the "Flow Value Calibrator"For example: http://www.thingiverse.com/thing:1662342.

The printing settings for each component are as follows:

Component 1: Base assembly

Support: None

Fill density: 50% and above

Resolution: 0.2 mm is enough. If you want a more refined surface effect, 0.1 mm is the ideal choice!!
 

Component 2: Slider cover

Support: None

Fill density: 50% and above

Resolution: 0.2 mm is sufficient, but 0.1 mm is even better!!
 

Component 3: XY slider

Support: None

Fill density: No special requirements

Resolution: 0.2 mm
 

Component 4: Knob

Support: None

Fill density: No special requirements

Resolution: 0.2 mm
 

Component 5: Pen holder

Support: Yes

Fill density: 50% and above

Resolution: 0.2 mm is sufficient, but 0.1 mm is even better!!
 

Component 6: Screw

Support: None

Fill density: 75% and above

Resolution: 0.1 mm gives excellent results - although 0.2 mm can also be printed normally, it is not recommended to use it, as the surface accuracy is slightly inferior.
