Tips and tricks
How it's done
Some of the tips that you might find useful before printing your model:
Print out a 20x20x20mm cube as a test print, to make sure everything is running smoothly and is well calibrated,
Feel free to use glue stick on your printing platform to make sure that your print does not move,
Depending on the type of your prototype (is it for your eyes only or is it a prototype in a final stage?), make sure to choose the right printing speed, layer height and quality of the print.
Layer heights vary from printer to printer, but mostly they are between 0,2 - 0,5 mm, with a huge time difference between them.
For your first stage prototype, where you will test the size, how the object feels in space, etc, there is no need for precise printing, so choose 0,4 or 0,5 mm layer height. For more precise objects, when you feel that the design is coming together, use more precise printing (0,2 or 0,3 mm will do the trick),
If your printer has two extruder heads, for higher quality prints use the smaller extruder, and for lower quality make sure to use bigger extruder,
45 degreee rule is a common way to model something when you do not want excess supports. This will greatly improve surface finish.
0.25 mm tolerance is used when designing two objects that will fit together. For example, if you have a 10 mm diameter hole, the tube that will fit inside it should be 9.5 mm (0.25 mm on all sides),
