I read an article lately about an experiment done by Dr. Nicole Prause. This inspired me to come up with a project using 3D printers in able to make instructional aids more readily available for this taboo subject. Teachers will also be able to customize their teaching tools. In addition, if parents want to teach their children, they now have a much better source than either just using a banana or going out and buying a realistic dildo.
Prause, N., Park, J., Leung, S., & Miller, G. (2014). A new method using 3D-printed stimuli: Women's accuracy and preferences for different penis sizes. manuscript under review.
I optimized these things to be printed in ABS with maximum settings. I would recommend a skirt with an offset of 0mm (otherwise known as a brim) with 2-5 loops for ABS. As can be seen from the photo, an increased infill may be helpful as well. I would also increase the shell layers to increase smoothness.
For this project I used a free program from Autodesk called TinkerCAD. I have long been a user of AutoCAD which is a desktop drafting program from the same company. I used TinkerCAD to make it easier for educators and learners to be able to more easily replicate what I did. TinkerCAD is awesome because it's not only free, but it's easy to use. It also runs in your browser and has built in instructional lessons.
I thought the designs were already pretty well thought out, so I used them as a starting point.
I wanted to make them a little more realistic, so I used the 'paraboloid' feature in TinkerCAD for "just the tip." I am hoping for some feedback before I go through the process of designing all of them this way. See aa_1.2 for my adaptation.
This project was created to help young men and women not only understand the importance of using condoms, but to also be able to practice using them effectively.
This is intended for students going through sex ed, or anybody who will listen.
- No prior experience needed, but teachers should be comfortable answering questions
- Condoms should be purchased ahead of time in a variety of sizes, brands, and textures
- Thought should be given to latex free condoms in-case of allergies
Step 1: Do your homework
Step 2: Print!
Make sure you print out a variety of sizes and extenders.
For something like the guy above, try zz_1 and zz_2
Or for something like this guy, try aa_1 by itself
Step 3: Excuses
Explain some common reasons people use to not use condoms.
Step 4: Explain
This is where your research comes in handy. Make sure you explain things like STD's, pregnancy, and the ineffectiveness of other forms of birth control. You should also be prepared to explain common misconceptions such as using two condoms.
Step 5: Practice
Set the models and extenders on a table and have your students all pick out different sizes. Demonstrate the proper technique and them have them practice on their own. Have them practice using different sizes of condoms so they can see the importance of picking the correct size. Also make sure that each person try's different sizes of the phallic symbols.
Step 6: Questions
Have all students write down a question at the end. Answer each question while maintaining anonymity.
At the end of this students should be more prepared for the under-explained world of sex. The should know the dangers and how to avoid them, as well as be ready to discuss it with their partners. This should be a pass/fail grade. If you want, make them passing reliant on the end questions to make sure that everyone is participating. Students should also be encouraged to ask their parents permission to print their own at home. Another great thing about teachers being bot to print these for so cheap, they could just send each student home with their own for more practice.
