I HAD done a bit of research into slicers, 3D CAD programs and the like. At one time, I could work in Auto-Cad, but that was many years back and I've forgotten most of what little I did know about that.
However, this printer is a SnapMaker (Chinese) brand we got off B & H Photo with all sorts of warranties on it. Took 45 minutes to unpack, assemble, fire it up and calibrate (level the plate). First print project was a simple flat dipole center insulator designed to have an SO-239 in the middle and was 100 percent infill for strength. That one took about an hour and a half to print and printed without any issues at all. They included a 1 kg spool of white PLA as the starter filament but it will work with ABS as well as several others I can't remember right now. I've ordered some quarter kg spools of various PLA colors and a 1.5 kg spool of black ABS jut to have on hand. Thingiverse has a whole bunch of ham radio projects including a spinner knob for my KX2 and THAT is going to be the priority project as soon as the black ABS gets here. I might even print it in the white PLA as a test run to see just how long that one will take.
The only drawback on this printer is it's 4.9 x 4.9 x 4.9 inch print area, but for now I can live with that (famous last words, I know!)
2nd project was a nice little dual lever paddle (also from Thingiverse) that only took a bit over an hour and a half to make all 4 parts. I still have to work out the paddle contacts and wire it up, but I do have the fixed ground contact (5mm x 2cm brass hex standoff) and solder lug in place - old ball point pen spring and all I need now is to make a through hole nut for each paddle (I have a Harbor Freight milling machine) and set up some adjustable contacts on each arm plus wire it all up. Like you said, it's just starting - LOL.
