## Creating a 5mm diameter / 1mm deep hole

Dear all

I finished my model inside Blender. I now want to use meshmixer to cut hole in the STL to position my magnets. The magnets are 5mm in diameter and 1mm deep. How do I make this type of hole in meshmixer? I know how to bool a hole, but I don't know how to have it the size/deep I need.

Any help?

In Meshmixer you use other models to cut away at other models, called Booleans. This would be a boolean difference:

1) Create a cylinder at the dimensions you want for your hole.

2) Place the cylinder in the object using Transform

3) Click on your main model, then Shift+Click the cylinder

4) Boolean difference

If it goes red and fails, remesh or play around with the settings until it works.

You can also use a MESHMIX  part dropping. This is a nice solution for parts follow the surface they are dropped onto:

1. From MESHMIX/Primitives drag and drop the cylinder to empty space. This generates a new object and switches to Transform where you can set the dimensions of your hole. You want to set SizeX = 5mm, SizeY = 2mm (twice the depth) and SizeZ to 5mm.
2. SelectAll of that object and run ConvertTo/ConvertToSolidPart. The scene changes to a bright background and in its MakeSolidPart dialog enable MaintainDimensions. Accept.
3. Now this part is added to MESHMIX/MyParts. From there drag&drop it onto your surface. Set CompositionMode to BooleanSubtract and move it to where you want the hole
4. Accepting this will automatically generate that hole.

Thank you very much... But I didn't understand. I'm sorry.

Please see the images attached. I would like to make a 5mm 1mm deep hole on both cubes faces where my cylinder is. I can't understand how to do that. Once I have done I want to insert a magnet on both parts.
