So, you've 3D printed a fantastic case for your Raspberry Pi, Arduino, or custom gadget. But those pesky ports, buttons, and screens need access! Fear not, creating custom cutouts is easier than you think.
First, **measure accurately!** Use calipers or a precise ruler to note the dimensions of the components needing exposure. Next, choose your weapon:
* **CAD Software:** For ultimate precision, programs like Tinkercad, Fusion 360, or Solidworks allow you to digitally design the cutouts directly onto your case model before printing. (Ideal for planned cutouts)
* **Post-Printing Modification:** For existing cases, a rotary tool (like a Dremel) with various bits is your best friend. Start with a small drill bit to create pilot holes, then carefully enlarge them with a cutting or sanding bit. Always wear safety glasses! You can also use hobby knives or specialized cutting tools for cleaner edges.
**Pro Tip:** For post-printing modification, mark the cutout area with a fine-tipped marker or pencil. Start small and gradually increase the size of the cutout. This minimizes the risk of overcutting and ensures a snug, professional finish. With a little patience, you'll have a perfectly functional and aesthetically pleasing 3D printed case.
