Superman Magnetic Whiteboard Marker Holder
I made this magnetic whiteboard marker holder in the shape of Superman lifting a rock. It sticks onto a magnetic whiteboard and holds your markers, making it a fun little print for a classroom, office, or workshop.
I used three 12 × 3 mm magnets, which worked well and kept the holder attached to the board securely.
The model can be printed without supports if your printer has good bridging. However, I would recommend using supports if you want cleaner inner wall quality.
I have included two versions of the model. The first version has magnet holes designed for three 12 × 3 mm magnets. The second version has no magnet holes, so you can add your own holes if you are using a different magnet size.
For the magnet holes, I found that making the hole about 0.1 mm larger than the magnet diameter works well. For example, if you are using a 12 mm diameter magnet, I would make the hole around 12.1 mm in diameter.
