Arduino coaster

Prints (0)



I have modelled an Arduino coaster, to place my drink. I use an arduino (kloon) for little youtube tutorials. I get my microcontrollers from China (Shenzen) cause they are so cheap. I also order a couple of sensors (also from Shenzen) and i start copying sketches (codes) and projects from youtube. It is really fun to do. At Aliexpress i buy all this stuff for around 20,- euro (~$20,-). Arduino is open source, so any company can remake these microcontrollers. You can ofcourse also choose to buy an original Arduino, this way you support the brand directly.

This is a standard size coaster (100 by 100 by 5 mm), to fit in my coasterholder:

I have printed this model with Ultimaker white PLA and Ultimaker silver metallic PLA. I used 0.2mm layer height and, 18% infill. I used a 0.4mm nozzle with my extruder at 210 degrees Celcius. I used a heated bed. To avoid the curling up at the bottom i used a brim. I paused the print at the point when the text began, changed filament, and resumed the print.

Design process

I picked a logo from my browser and have put it in svg format in inktscape. Opened the svg file in blender and made it a 3D object. In meshmixer i have repaired the file; and erased some aspects. In meshmixer i have also added a coaster. Than i have merged the coaster with the picture after scaling the picture. Saved it as a STL file and sliced it for printing. Cause the model has still some issues even after repairing it in meshmixer; i have decided to export it into Netfabb Online Service. This is an app i discovered recently after using MakePrintable. Cause MakePrintable in my opion only gives us 3 procedures of fixing an STL file and, with Netfabb Online Service the frequency of STL fix procedures is unlimited, my choice was clear. It worked well for me and i could slice the model without any problems.

If you would like to know how i design a 2D picture (google) into a 3D model. Use this link: (video is under 6 min.)
