Note: this includes LaFactoria3D's original mask parts that this is designed to fit. It's a great design, and I include it here because they have since updated the mask base in a way this cannot fit. If you feel their updated version provides better protection I urge you to use it instead.

Replacement cap for LaFactoria3D's COVID-19 MASK

While printing mask parts for Lowell Makes I wanted to find some way to help healthcare workers relieve some stress. Making replaceable caps seems the best way to help; these clip right onto existing masks without interfering with function and maybe they can lighten the mood in pediatrics.

Another request: Mobile Suit Gundam's ubiquitous RX-78. I haven't yet had time to test print this but the fitting is relatively simple and should work with little trouble. I expect it would look best with the Giant Robot Cap that ThinkGeek used to sell.

• The main piece can be printed in it's current position but I would block any supports to the top connection shelf (it should work fine without them). This would save time and material, but if in doubt don't bother blocking them.

• The top piece will also need supports. Cura shows it slices well when angled (nose upward or downward) around 45 degrees. I would do that anyway if only to get a cleaner top surface with fewer layering steps.

• The other two pieces should print cleanly without supports, but you know what your printer can handle better than I do.

Instructions on how to assemble the rest of the mask efficiently and good materials to use can be found here, thanks to GiveWave Studios: https://youtu.be/9ItpExBEieY

If you find any issues with it or it my instructions are not clear, please let me know so I can make adjustments.
