... system is responsible for allowing us to see and interpret light and color. It consists of the eyes, optic nerves, and associated structures such as the retina and cornea, working together in perfect harmony to detect and process visual information.

This part is not needed to have a functional piggy bank, it is just for optical reasons and would probably look even better when printed in color. Main Body Files: "Unicorn Piggy Bank - Blue" - used for middle hair and part of the horn "Unicorn Piggy...

Five 5-watt blue LEDs producing 450 lumens each are combined with high purity optics to produce a narrow 5° degree spread spot beam, providing a high intensity center beam which is visible during daytime and nighttime operations. An adjustable...

After my IKEA Lack table was a bit too unstable for me and would've optically no longer fit well into my new apartment, I decided to build another (strong) housing for my printers. In the print files you can find some Remixes or Self creations of 3d...

This can be triggered with as little as 3v, and both sides are isolated, meaning the Raspberry Pi will never come into contact with the mains voltage of 240v (the relay probably uses an optical sensor). Relays like this do leak which is not good for...

A pair of Seoul Z-Power® 10 watt LEDs producing 1800 lumens are combined with high purity optics to produce a 10 degree spread spot beam approximately 225’ long by 45’ in width. We also offer floodlight versions with a 35 degree beam spread to...

The image quality is quite good with a short focal point and the optical magnification is very useful for surveillance of the 3D printing process.  Background: My last project, the 3DO cam despite superior image quality (when working) had the...

Extra parts required: - M2x10mm cap head screw x1 - M2 hex nut x1 - M2x6mm screw, black finish, x3 - M3 hex half-nut/jam-nut, brass x1 - M2x20mm countersunk screw x1 - [M1.7x6mm plastic self-tapping screws...

 This is modular Dreamcast GDEMU (optical drive emulator) mounting system. It's designed to fit several criteria: - Rigidity and sturdiness; - Restoration of...

For me it was clear, there must be a successor and here it is.The body kit for the MK3 and MK4 series is a purely optical upgrade which is designed solely to ensure that you have even more fun with your printer! It is a solid model which, when...

Also one of my printers now actually has a 0.6 nozzle, so for it, Cura not only outputs the above height and thickness, but does so for printing things even more quickly.  There is an LED on the controller/interface (that signals connection and...

...The two colors normally would be placed in front of two separate lenses, however, it suffices tocreate two optical paths within a single lens. This is done by a type of dualWaterhouse Stop -- a fancy name for an opaque material with two holes in it.

Note that this design requires an optical acrylic dome of some sort, the one used here is sold at a modest price by Orion as a spare part for their own AllSky camera. It's worth using a high-quality dome like this to get the best image quality...

For an optical filament sensor, you might want to take a look at this thing on Thingiverse: https://www.thingiverse.com/thing:3021660. If you're having issues with your Da Vinci 3D printer's extruder thermistor, you can check out this article from...

As a little side note, the sensor is inductive, not optical. I'd seen it asked on the store page, so I gave it a test to find out. I'm pretty new to 3D printing and this is my first uploaded Thing, so if you have any tips, I'd love to hear them! ...If...

If shooting a full 4x5 frame, expect extreme optical vignetting at the perimeter of the frame. Photographers who use this technique often aggressively crop the resulting image to exclude underexposed portions of the frame. Featured sample photos...

Now I know you're gonna tell me that hardly anyone uses optical drives any more. But I still do! Only occasionally, it's true! But I still like the convenience of simply opening a tray and whacking in a disc when needed, rather than having to dig a...

 However, I soon realised that the most significant limitation wasn’t the lenses or my adaptors but restrictions set by optics. For example, the closer you are to your subject, the smaller the depth of field (the region in focus). Macro photography...

This is a prototype for an optical sensor that measures the width of plastic filament in real time as it goes into a filament extruder or 3D printer. It is prototype #4 (other 3 are on Thingiverse as well ). For filament extruders, the measured...

I had seen a number of other projects with optical and mechanical switches, but none matched this batch of microswitches I had on hand, so off to SketchUp to design something. This is designed to be both a filament guide and a sensor. On my machine...

Alternatively, you can just glue the whole thing together or if you're extra lazy like me, you can use a optic of some sort to secure the connection between the two. 4. To use the peep sight below the rail, you'll need to carve out the small...

Some parts will be added in future. If you need additional info, ask in the comments section, so everybody can read it :) Feel free to ask, remix, print, edit and say thanks. After my IKEA Lack table was a bit too unstable for me and would've...

This sensor is smaller, simpler, more robust, and impervious to dirt than optical sensors. There's a reason why Hall sensors are used in cars ABS isn't? Note that I integrated this kind of sensor into my direct extruder. It just adds three grams. I...
