FFF/FDM 3D Print Keycap.
Especially regarding the stem part, it is designed to optimize the movement of the tool head for FDM 3D printers.
My environment: VORON 2.4 R2 350mm with 0.4mm nozzle (Phaetus Dragon HF). Below are settings in PrusaSlicer for reference. There may more accurate and faster print settings.
To avoid choppy nozzle path, set Perimeter Generator to Classic. If arachne is selected the path will be messy!
Sliced image, especially stem, should be like this. If the nozzle path is choppy, adjust the settings.
ABS or PLA is easier to print. PETG lacks shaft durability and is prone to clumping, so it is not recommended. When ironing, PLA is the best.
