So, one bright day, when i will be the proud owner of a Original Josef Prusa 3D printer, i would be a happy man. But for now, this version 2 of an Original Josef Prusa coaster, will work just fine 4 me. I will use it in my house to put down my favourite drink. Coffee that is.. .with a lot of milk; made the old-fashion way. You can also use this coaster to put down your favourite drink. Remember, you can scale it up or down. And use your favourite colour filament, as also your favourite slicing-settings. I'm sure you will have no problem printing this model. As it has no overhang and so it doesn't need support material. But when does a drink-coaster need any support huh?
This is a standard size coaster (100 by 100 by 5 mm), to fit in my coasterholder:
I have printed this 3D model with white Ultimaker PLA. And my resolution is 0.15mm (normal in Cura). My infill-rate is 18%. And i have printed the object with my 0.4mm nozzle at 210 degrees celcius, with heated bed. I used no support. I used a skirt just to get a good first layer, but if your machine primes at the beginning of every print your good to go.
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 to Make Printable. This is an app i discovered recently in thingiverse. And also this time, it worked well for me and i could slice the model without any problems.
