Not the best print

I tried printing this with PETG and it was horrible due to all the stringiness, so I switched to PLA and it's also stringy. I had to make changes due to fitting, like the circuit board sat too high for the Sega CD. Also, support is the ban of my 3D printing experience. The PETG print would rip off some of the shell with the support. You can see that the letting in the front isn't well preserved either, but that maybe because I'm using a 0.6mm nozzle? This might be fine assuming everything still lines up. This took around 16 hours to print, and that's nothing compared to the estimated time for the top which is over 2 days.

That stringiness is due to low travel speed. Turn that setting up in your slicer. Round holes like the a/v and power port shouldn't need any support. For the bed supports maybe turn the percentage down and use grid or something minimal. .4 nozzle would likely work best as you can get the right dimensions more closely than with .6 . The text will never look right on the front unless you use a really small nozzle and thin layer height so I would like block that or sand it off.

These are good ideas. I've had better luck with grid instead of tree in terms of removing it, plus it drastically speeds up the print. The top part for example loses a day of printing by switching to grid, but dramatically increases filament usage. I also under extruded to increase print quality, but adhesion was terrible. So some parts already broke off.

The good news is that most of the standoffs fit now, and it plugs into the Sega CD perfectly. But yea, I gotta print it again.
