After trying various pivot structures, we settled on a double rack-and-pinion derived from janssen86's Gear Rack and Pinion; the (rather tiny) gear core serves primarily to keep the pivot point from moving, while the herringbone pattern of the gear...

There are inside 24 adressable RGB LEDS (mounted on a circle PCB), so you will be informed with colors what's going on: when there is nothing on it - everything is turned off, when you initially put the hot cup for the first time, proximity sensor...

From huge sculptures of the war God Ku to pictures of various gods carved into drums, boats, or other utilitarian things, to petroglyphs etched into rock or tattoo patterns on the body, the Tiki can take many different forms. Tikis show a great level...

All the chess pieces will NOT require support during printing.  6/1/2023 - Added two hinge test print STL files.  Print settings:All the tolerances of this project was design to be printed using 0.4mm nozzle at 0.2mm layer height. Layer height:...

This is not me just punching holes for the fun of it, I was trying to give the user of this design the flexibility to use any bolt pattern they want. Any new skills you have given to Chip-E: I gave Chip-E the ability to be expandable and modifiable...

Mostly just print, cut, and stick.Notes:Beware of printer color correction settingsSizing is finicky; Irfanview was the only reliable way I found to print them; other applications resulted in resizingSome of the decals require cutting the interior,...

The AMS colour changes work effortlessly, and I am able to start a print with the external spool in a matter of seconds.Print SettingsMaterial: PETG (optimal) - PLA (best) Layer height: 0.08mm (optimal) - 0.12mm (best)Walls: 4 (highly...

Use either concentric infill or a lot of perimeter lines - the hub will have to be rebored later, and concentric print lines will result in better rolling properties than other patterns after reboring. To print a pair of spring-loaded rims, you...

I also uploaded four variations of all jaw gears from .05-.20mm clearances.UPDATE 10/22/2022: Added a STEP version of the Visible Screw Base for anyone wanting to make their own custom hole patterns.UPDATE 11/26/2022: VK4IU commented on an issue with...

([PR #2844](https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/pull/2844)) - reworked the buzzer handler, it is purely interrupt based with the benefit of more consistent sound patterns and no interference with other tasks ([PR...

In my case, as I have 30 LEDs in total, I can fit 6 lines of 5 led strips.Adhere the LED strips to the back plate in a grid pattern.Join the now disconnected LED strips back together (I used some basic jumper wires that I got in a random Arduino kit...

The first is, when assembled, the EM drive section had some noticeable gaps along the seams due to the waffle pattern of grooves along the underside which serve to align assembly. Fortunately the grooves needn't be extended all the way to the edges...

A spring-powered toy cannon, designed in the pattern of the mid-19th-century 12-pounder Whitworth rifle, suitable for playing H. G. Wells' seminal miniatures game Little Wars.</p> <p>See the sections below for more information.</p> <p>(The toy...

This is technically doable without that piece as I have other 3D printed guitars without a piece like that, but I've seen it where an improper gluing or other factors may cause catastrophic failure when tensioning the strings.In order to have a full...

&nbsp;The pattern of the disturbed water surface would indicate biased or centered flow.&nbsp;In the pictures attached, it shows the flow to be left-biased, side-by-side to the same test for the X2 that shows a more balanced flow.The X2 has the mods...

&nbsp;If you load the corresponding Prusa Slicer project file, you can proceed and slice the model directly, but if you load the STL files directly, you need also to create an infill modifier loading the infill STL piece that will be used for...

I've ordered one and plan to use it when I build the robot.Printed at .2mmInfill 70%Fill Pattern: Adaptive CubicIt should be heavy enough when printed, but still has screw hole to secure it...

Of course, the hexagonal pattern can stack and tile together with no gaps. The proportions allow 5 to be lined up longways to match 7 lined up shortways. This is for efficient packing on a shelf, but also packed into the foot print of a standard Euro...

We decided to add that to the display stand in a raised relief pattern. This completed the 3D printing aspect of the build.</p> <p>The fins were cut from bass wood instead of balsa wood. This should give the model some added strength. As this is a...

The 140° beam offers a very wide lighting pattern and is ideal for situations where lighting distance is not a concern, but illumination of a wider area and even light distribution is. The 140° beam is great for situations that call for working in...

This saves material and makes it easier to get pieces out. Added shaped holes in the bottom of vertical stacks. v1.12 Better support for compact fits. Bug fixes and optimizations. v1.11 Now supports rotation of features. v1.10 Under-box storage...

The side hanger though required a change to grate pattern in the Body so they're symmetrical. To accommodate the Top Inlet I created a wider version to move the rollers outward. The Body and Roller dimensions are same between versions so either Top...

The visual system plays a vital role in regulating vision, detecting movement, and recognizing patterns. The human auditory system is responsible for processing sound waves from the environment. It includes the ears, which detect sound waves and...

The main problem is precise printing over large distances with multiple parts. I've strengthened the radiator support on the PCI-IO part, as it was too flexible during printing and led to less than clean prints. V0.33:added more supports to the AGB,...

here are the specs : - 5" (5.5 actually) or 6" WideX arm options - HD capable with cam plates - 6mm thick arms (for strength and vibration management) - reinforced front (2.5mm front and cam plates) - supports 16x16 M3 motors (from 22xx to 25xx at...

And for the large trestle you will need 10 Main Frames, 4 SideBraces + 2 CrossBraces, 12 Runners, 1 Bridge Top 10.5in 1, and 1 Bridge Top 10.5in 2. The SideBraces STL is made up of 5 CrossBraces STLs, laid out in the correct pattern for attaching to...
