One month ago, I didn't really know what 3D printing was. Yesterday, I designed in FreeCAD my first model and printed it. What an amazing experience.

I still have no idea what I'm doing really. Just too determined to give up I guess, and it's been such fun. Anyway I made a guitar pedal light switch cover. Still a lot of work to do, and every time I look at FreeCAD the wrong way, the model breaks, but it's been a fun experience nonetheless.
On a side note, anybody have any idea why the face of the model is rough textured, while the foot switch on the lower half is flawless?
You're viewing a single thread.
Did you print the foot switch upside down and then flip it? If so, how does its other side look?
I can’t tell how the surface quality is by the knobs.
Your “main” top surface looks like under-extrusion.
It's all a single part, so that's how it printed. I have a sneaking suspicion it's because of how I did the steps in free CAD, not having a clue what I was doing, etc. before I pass any judgment, I'm going to print other files and see if the issue persists. I'm already planning to rebuild the entire thing in free CAD again, using what I've learned in the process
It’d be interesting to see what it looked like in the slicer, just in case it’s obvious there.
And yeah, each new FreeCAD project I do builds on what I’ve learned and it gets easier to get better results.
Here is a link to the STL, if you want to poke around. https://www.printables.com/model/700351-guitar-pedal-light-switch
One other thing that occurred to me is squish. Just like your first layer issues, the plastic on every layer needs something beneath it to squeeze against so it converts from a circular tube to a flat, wide oval. Maybe your slicing didn’t have enough support or infill in the main body as compare to the final top surface? You could try increasing the horizontal shells.
By the way, I assume you did not turn on ironing, because that could also affect the surfaces differently if one got ironed and the other didn’t for some reason.
