- Robb commented on Robb's instructable 3D Printing and CNCing Weird Freeform Lenses
Hi! That type of lens is called a Fresnel (pronounced freh-nell) lens. They are very precise objects that cannot be 3D printed due to the inability to get into the crevices to polish the surfaces. Most consumer printers are FDM, which use filament to make objects. These printers unfortunately cannot make lenses directly, as the resolution is too small and there are many small gaps in the object when printed. you would have to make a mold and cast your lenses out of resin or silicone. Another option is to use an SLA printer, such as the Form 3. Also, in order to increase the efficacy of a photovoltaic panel, your lens would have to me much larger than the panel. It would be much cheaper to buy a bigger panel, or to use mirrors. https://en.wikipedia.org/wiki/Fresnel_lens

It works great, I promise! The wheels have very little friction on the smooth wood edge. Skateboard wheels are designed for much rougher surfaces than sanded wood. Note the wood is two edges on 6-ply plywood, so it will not wear like normal wood.

Hi Jeff! I am glad you think I am clever. Instructables is a safe space in every way possible. It is made safe by a team of dedicated moderators, developers, and community members. I have had the privilege of working for Instructables at their SF office with the lovely, open-minded, and diverse team there. I assure you that the instructables space is safe, suitable, and appropriate for gender nonsense of all kinds. I think you will find as time wears on that this 'gender nonsense' will make more and more sense to larger swathes of society, as LGBTQIA... people and those who love them are everywhere and this sort of nonsense is exactly the nonsense that keeps us up at night.

Hi DropKick! I'm glad you like my 'ible. I am glad it is stirring up the critical discourse it is intended to provoke! It is a very nuanced subject.https://en.wikipedia.org/wiki/GenderTo echo what SiouxsinT expressed, gender is of course a scientific term, but it is not a synonym for sex as you describe. Gender and sex are often correlated, but the relationship is complex. The word Gender only existed in linguistics for latin/Spanish/German/etc nouns until the 1950s(!) when it was intentionally introduced as a way to talk about the (scientific) differences between sex and the socialized behaviors associated with 'man' and 'woman'. A simplified explanation is that male and female are sexes, while man and woman are genders. Almost all animals and many plants have a sex, but gender exists on…

I would be very excited to see a solar version! Keep us posted!
I'm glad you like it! I agree, The half-half sign is very confusing. The best sign I have seen is a just picture of a toilet. http://itspronouncedmetrosexual.com/2014/04/gender-neutral-bathroom-sign/
View Instructable »Hey Paolo! The way I see it, it is more of a parody of the traditional sign. The best sign for a toilet is a picture of a toilet. :-)

I would love for it to be faster! I went with an easy to find motor, but my dream solar version would take about 2 seconds to change. That way it is obvious that it is moving! Thanks for your kind words. I'm glad you like it. :-)
