BetterMaskSeal is a moldable nose strip for a surgical mask that is heat molded to fit any face, using a standard iron for heating the strip. The strip needs to be molded only once and can then be reused after disposing your masks.

The resulting fit prevents fogging if you wear glasses and also improves both comfort and protection level of the mask.

Perfect gift for friends and family in these times!

Suitable for printing only in PLA.

  • Stay safe and wear a mask!

Came out Perfectly. Excellent Idea I Love the Simplicity of it. Instead of an Iron, I used a mini 300w heatgun to mould it to my face starting from the nose, then I did each side of the nose separately. I found the mini heatgun gives me more control and moulds to my face much better. On my Ender 3 Pro with BTT SKR 1.4 Turbo board & TMC2209 stepper drivers. I used these settings: 0.2mm Skirt of 2 lines (0.15mm from model). Printed In ST-PLA (Creality & Elegoo). I find ST-PLA is more durable-flexible and I can re-heat it, straighten it out on a steel ruler & remould again to my face (see foto).
Awesome Design & Well Done :-D
