There are very very few supports required to print the modular Omni pieces. In fact, you could get away with printing without any supports, but there are a couple of pieces where we recommend adding supports (we want your cases to look flawless, it is designed to look like a finished product). All places where supports are recommended are included in the PDF and video. We will also be providing a detailed description of our recommended settings and gear!
Our favourite Omni - The 330x330 Square Display Case takes roughly 80 hours to print all of the pieces. When we use more than one printer we split up the Omni and get them printed in less than one day which is pretty cool. With the new printers coming out we were able to print one in just 45 hours on the Bambu and we expect a very similar time once the Prusa input shaping software is released. We are hoping to post some videos here and on youtube shortly showing the process. Additionally, the Omni can be printed using a 0.6 nozzle which can also greatly reduce print times.
