When looking at the files, there are 3 identifiers. The shape, amount of holes, and the indent are listed. The buttons listed with a millimeter measurement are circles, while the squares and pentagons are all 23mmx23mm. If it says Dipped, there is an indent on the center of the button on both sides. If it says Flat, there is an indent on only one side of the button. If the model name ends with the amount of holes, like “Square4Hole”, there is no indentation on either side. For Dipped buttons, you may need to print with supports. If it says Short, that means that the button is 1.5mm tall, instead of the typical 2.8.
The author marked this model as their own original creation.
