One of the biggest challenges when introducing new technology in schools is getting busy teachers to take that first step. Many teachers from various subject areas are interested in 3D printing, but they're hesitant due to the time commitment...

The domes can be challenging to print, but I recommend slowing down the layers at the top to 50% print speed (around layer 670). Achieve optimal strength by using 100% infill with concentric infill, or you can set your wall count to a higher value,...

There are some challenges associated with this concept. The original pencils were held within a cap that was itself secured inside the cartridge case, necessitating a strong yet thin-walled "bullet" – a feat currently beyond the capabilities of 3D...

So, the biomedical doctor leader asked: "Guys, can you make it happen?" We looked at each other and, after a few seconds of intense discussion about the most daunting challenge we had ever faced, our answer was clear: yes, let's do it! Unfortunately,...

Filleting also is a challenge as I have to accomplish that with Minkowski sum of small sphere and the main parts with sharp edges. <p>The most painful part is that OpenSCAD is painfully slow when rendering at high resolution, as it is single threaded...

Just change the parameters in the Fusion file if you want to scale the design.If you are making this as a gift, the solution is on the wikipage, so you can package it.You need to print the cube, the lid and 27 cuboids:-1 x 'Cube.stl'-1 x 'Cube...

While I've also designed a double-helicoid mechanism, printing it with good results remains a challenge at this point. The focus range is roughly 30cm to infinity, allowing for a wider range of creative possibilities than traditional adapters would...

Printing the o-ring: The challenge here is ensuring it's compliant enough to form a good seal. I used TPU with one perimeter and no infill, but make sure not to under-extrude, as water could leak through the printed seal itself. A very smooth bed...

The VS-50AR has a dummy pressure plate on top and its external appearance is very similar to the VS-50, posing challenges for demining personnel. Additionally, Valsella manufactured a separate electronic anti-handling device known as the VS-AR4. It...

The whole structure consists of 3D printed parts, CNC-milled parts and purchased RC model components and is certainly a small challenge for the ambitious model builder, as some manual skills are required from time to time. So for those who are...

What sets it even further apart is the use of electronically controlled rear differential and double clutch technology inherited directly from its impressive forerunner - that super-speed LaFerrari with every ounce and fraction in its possession...

The challenge lay in the fact that my client had very little left of his wrist, which meant the standard active grip system wouldn't work for him. I designed a passive grip system using retention springs, allowing the fingers to auto-adjust to...

There is one major issue with the camera: achieving exact perpendicularity to the surface can be a real challenge. By moving the camera up or down on the Z-axis, the image crosshairs can shift, compromising positioning precision. After some trial...

A little challenge never hurts. The railing bolts may need to be re-drilled, depending on how thick the cord, filament cord, wire or ball chain is. The start and end can then be invisibly inserted and glued into a post hole. Note: Accessories and...

But birds are also thirsty all year long and finding water to drink or bathe can be challenging for them. So that's my version of a water dispenser. You can find plenty on .stl sharing sites or YouTube. This one is inspired by many initiatives I...

The real challenge lies not in building it, but in creating a custom application environment that showcases its capabilities. Learning, combining, and developing innovative applications are what make this robot truly special. Community There's...

Don't let its looks distract you from the challenge though; happy puzzling! Printed on an Ultimaker 2+ at 50mm/s and 0.1mm layer height. Supports on the base and headpiece for the holes. Print the headpiece laying flat. I'll upload a picture of the...

Option 1: This mount should support any 80mm fan, 10mm-25mm deep with its adjustable nature, fitting a 120mm fan might be a challenge as the case is less than 100mm across... You need to print: 1x - Fan Shroud for Clips.stl 4x - Fan Shroud Clip.stl...

The 5mmx500mm rod presented a challenge; I had to add a bumpout on the gantry for the bearing holder to ensure the rod's length was sufficient. Ultimately, it works well, with parts conforming to standard sizes. Since the wheels no longer match the...

One simple yet frustrating challenge in crafting silicone soft robots is creating a reliable and airtight connection between the tubing that supplies your robot with air and the soft robot itself. As a solution, I've developed these specialized...

The most challenging part is removing supports without breaking thin parts. Be gentle when handling these minis. With some of them, better results can be achieved by splitting them in the middle, so I provided separate files for the halves. For all...

Here are the design specifications for this unique puzzle cube, crafted with precision and care to provide an exciting challenge for puzzlers of all ages. The custom design features eight distinctive block patterns, each one carefully balanced in a...

But in the end, it was not the beast that proved to be the greatest challenge - it was the village's own darkest fears, which threatened to consume them all. In the aftermath of the battle, the villagers surveyed the damage, their hearts heavy with...

Hello!After more than a year of using great, OpenRC F1 designed by Daniel Noree, we decided to take on the challenge of designing a working aerodynamic package for the project, and here it is!AERODYNAMICS & PERFORMANCEIt's a package of working ground...

Five years before the start of the Liturium War, Teverys faced his most harrowing challenge during the campaign on Duskweave Isle. He led the charge against the powerful undead forces that threatened the land. Despite suffering grievous wounds in the...

I enjoy the challenge of sticking blaster internals into places they were not designed to go, so when I came across this beautiful classic shell brimming with potential, it was an absolute no-brainer. I mean, it has “Foam Blaster” in its name! It had...

He is a theoretical physicist, holding a PhD degree, but somehow finds himself in the middle of a battle that threatens humans.The protagonist takes part in numerous challenges, fighting and eliminating aliens. He travels to the Xen world where he...

All parts were printed without supports as a challenge - but you can print them with supports if you prefer. I printed the tree sections with the top on the bed, which made it easier to assemble everything. To put it all together, start by adding...

Take every challenging situation as an opportunity to learn and grow. The best study method for working adults is distance education, which allows them to balance work, family, and focus. Pebble Hills University's philosophy is to prepare managers,...

Da Vinci Exotic Species Challenge Design: I employed photogrammetry using Agisoft to create my object. The progress can be seen in the included photos. Note that on my test print, the ears were cut off because they were too thin. I utilized Sculptris...
