Hi! This is my printable version of the classic Etch-a-Sketch / Telesketch - a kind of plotter-toy. You can draw what you imagine by rotating the X-Y knobs. It works great with a marker or a pen. The drawing area is 15x10cms approx. The X-axis acts like moving the complete paper, inspired by the Prusa Y-axis (moving all bed). This model has many parts and can print mostly without supports - I hate supports! I've arranged the parts in six files according to impression parameters and print order. A PDF with assembly instructions and some tips is included, along with a ZIP file containing all the STL files for each part. Also, 123D Design files are provided. See the Print Settings below. I apologize if my English isn't good - I'm from Spain and have bad grammar writing in English. UPDATE! The ZIP file 'all_parts_separated_update.zip' now contains the STL's with all the pieces merged (old files may cause problems with some slicing software). Redownload if you have problems with separated parts in the STL's. UPDATE 18-Sept-2016: ScienceMadeFunner published a great video on YouTube printing, assembling and playing with MicroSketch. Check it out! Video en Español is available here. Check this remix made by PowerScissor: https://www.thingiverse.com/thing:2696231 Have fun! Print Settings: Printer: BQ Prusa i3 Hephestos Rafts: Doesn't Matter Notes: Tested with PLA Only use Rafts if you really have problems of adhesion. I've printed without rafts and it works. Important: Adjust the 'flow' on your print software to ensure all parts fit with minimal sanding. Recomended using a 'flow calibrator': http://www.thingiverse.com/thing:1662342 Print settings by file: Part 1: Base Parts Supports:NO Infill 50% or more Resolution: 0.2 Part 2: Carriage Covers Supports:NO Infill 50% or more Resolution: 0.2 (it's ok), 0.1 (it's great!)
