This is a small spider I created in freecad just to see if I could print this small. The legs are 0.4 millimeters wide but the slicer wouldn't recognize the legs so I had to print it at 1.5x scale.
Printer Brand:
Prusa
Printer:
i3 MK2S
Rafts:
No
Supports:
No
Notes:
Had to lower the print speed to 10mm/s to have the legs succeed. I also had to scale it up 1.5x to have slicer connect the legs correctly, but that's using 0.4mm nozzle, your mileage may vary.
