These are two models, a batman positive and batman negative file. If you print it for a drinkcoaster, i would print the negative one. Cause that one provides more stability for your glass/cup.
I haven't printed these models (yet). But i have previewed them into my slicer (something i advice to do first before starting your print). And i have seen no problems with the detail.
Print it with a single or multiple color, with filament or resin..and show me what you guys have made of it (if you don't want to post a picture of your print it's totally fine)
Use this coaster to house your favourite drink.
This is a standard size coaster (100 by 100 by 5 mm), to fit in my coasterholder:
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. For the negative model i have use 123design to substract the file from a drink-coaster. 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:
