About this 3D model
This tool helps you to find the center! (At least that of a board)☺ It can be used for a width of up to 96mm . (If this is too small, simply make it bigger in the slicer) ;) The hole size in the center is 2mm . So ballpoint pens and other rollerball pens fit easily. The width is also ideal for pencils. If you have any suggestions, please write me a comment :) Or if you have ideas and don't know how to realize them, you can also contact me :)
