The idea is to create a template or process to easily print a menstrual cup for those who need it.
Not everyone has access to the Internet, enough money to buy a ready-made one, a vacuum chamber and silicone.
My idea is to send the model and the tpu filament for example in fablabs and they can print it quickly. Anyone can participate in the fablab, for example by making a free donation in a box next to the printer, for example. We will therefore be able to apply this principle in developing countries and in all places where there is a person in need.
It all started on Thingiverse and Todahl who was able to print it first and give me feedback on the file. She also posted it on the 3D printing group on Facebook ,which allowed me to get positive as well as negative, disgusted or amused feedback.Unintentionally they all participated in a discussion about the female body and the taboos it still represents today.
Mentrual cup patent 1867
I don't need to copy a block I found on Wikipedia.
The goal is to have a fast and healthy printing process to avoid a silicone mold (not everyone has the ability to buy this material and does not have access to a vacuum chamber)and to allow a faster and more personalized production.
This model (available on Thingiverse in the files section) would allow to personalize the size directly, and the shape for those who have specific pathologies (low cervix ,vaginism)or allergies (we could thus change material for those allergic to silicone, the medical TPU being the most appropriate)
This would allow people who do not have access to sanitary protection (or who manufacture it with on-board equipment) to go to school, work and avoid infections that can cost them their lives. And also to make significant savings (between 5-8€ /month, pink tax etc.)
I hope that if this works, some companies will be able to send filament to fablabs and other third parties to manufacture them.
This can also be the subject of discussions/discovery workshops around the female body.
I know that this problem is often accompanied by the problem of accessibility to toilets.
I invite you to watch this video about the work of the movement Right To Pee (A movement for free,clean,& safe public urinals for women in India,An initiative of CORO India,with many more women organisations create by Mumtaz Shaikh ) and learn about projects such as Clean Your Cup.
I leave you articles on the accessibility of hygiene protection in some countries and on the rules in general, as well as interesting articles on the materials I thought I would use.
I invite you to read about it in order to get your own idea of the project. Feel free if you have any feedback or interesting articles to report to me. (in English, French or another language)
