Use your slicer to scale (resize) if needed until it does not touch your nose.
3D print sideway works better.

You can add some fabric on the sides so that you have the fabric touching your face for extra comfort.

I designed this mask "enhancer" to improve the shortcomings of "turtle" mask enhancer (Amazon or TV ads). Same idea, to improve breathing without comprising the mask itself. It holds the mask from collapsing, maximize the breathing space inside and less heat and moisture built up. This design is more universal to fit any facial structure (everyone is different), and covers more surface area of the mask and easier to talk than turtle mask.

For additional comfort, you can sew two pieces of fabric to fit into the sleeves. That way you put on, the fabric is in contact to your face instead of the plastic.

There is another design with a fan insert for going to a gym. The size of the fan is 4cm x 4cm. I use a 12V 3D printer fan, powered by 9V battery and it works. You can put a more power fan for high intensity exercise.
