Some may already know this iconic and flexible figurine, but those who don’t know it will also be able to enjoy this new version. Fully articulated, Dummy 13 is great for posing and decoration. Even though it’s still a work in progress, the designer decided to share this beta version because most of the design is complete.

The action figure is made up of an internal structure and armor, so it’s very important that you use a strong material for the structure, such as ABS, ASA, or PETG. The designer doesn’t recommend PLA for the internal structure, as it can break easily, but PLA is okay for the armor and also creates the opportunity for interesting color combinations.

It’s very important that you keep in mind that the parts are very small and do not require support or orientation adjustment. Good bed adhesion is essential for a successful print. Don’t forget to check out the additional recommendations to get the best quality possible; the designer left a table with details.

First-person view drones and 3D printing have become very familiar with each other over the years, with more and more pilots turning to the medium for replacement parts and custom designs for their drones. This miniature drone utilizes an ABS frame and canopy to house all of its electrical components. While 3D printed frames are often criticized for their durability, this project takes advantage of the lightweight nature of filaments to require less power from the motors for a longer flight time.

The Whoop-style drone features a range of 500 meters and weighs in at just about 45 grams with a GPS unit attached. Speaking of, the GPS unit is the only component of this build that requires soldering. If you aren’t comfortable soldering your own electronics, you can forgo the GPS unit for a solder-free drone build.

The designer also has other drone builds available if you’re interested, such as their long-range drone that’s powered by a single 18650 battery.

Those who enjoy painting miniatures know that one of the most difficult parts of the hobby is keeping a good grip on the figures without ruining the paint job. Often, they’ll resort to using clay or blocks of wood to get a good grip on their figures. However, a proper tool can improve the whole task.

This miniature painting hand clamp is a worthwhile upgrade that will make it much easier to maneuver your figures while painting. The handle itself is a very simple print, requiring only a few different pieces – all of which can be 3D printed, though there are a few that can be replaced with hardware if needed.

You’ll want to print the grips in an elastic filament such as TPU for the best results. Assembly is quick and using the screw to position the arms is very simple.

Born of a high school engineering project, this mini lathe allows you to turn wood and soft metals and make useful round parts. Typical mini lathes and tools cost as much as – or more than – a mid- to high-end hobby 3D printer, so this project offers a budget-friendly option for those who want to try out milling but don’t want to invest in expensive and bulky tools just yet.

Since it’s held together by printed plastic brackets, many may doubt the usefulness of this lathe. However, the original creator claims that he and his robotics team were able to successfully mill aluminum and brass and, if you do it slowly enough, you may even be able to turn steel. Impressive!

For those who have children, you know that a seemingly harmless brush can create more art than you could have imagined and on every possible surface. Usually, a small disposable cup of water is sufficient to clean brushes, but disposable cups are terrible for the environment. This solution, in addition to being fun, is a better option.

There’s a small flush system that cleans the brush and changes the dirty water. The water tank is gravity fed; nothing electric is required – just the physics at work here. The reservoir can store water for up to 12 flushes, and you’ll need a spring and perhaps a thin piece of rubber for the valve. The project page includes detailed assembly instructions with images. With the designer’s print profile, the average print time varies between 10 and 11 hours.

If you want to get good photos of your 3D prints or are looking to get into photography on a budget, a 3D printable tripod may be exactly what you need.

This tripod project functions exactly the same as traditional devices, with plenty of control for the height and angle of the camera. It comes with attachments for a DSLR camera as well as your phone. All of the printed parts will fit comfortably on a 200 x 200 x 200-mm build plate, and the whole project should only use about 600 grams of filament. While PLA should work just fine, you may want to use more durable materials such as PETG or ABS if you want a tripod that will last, as there are quite a few moving parts.

Fully extended, this tripod can reach up to 85 cm in height, carrying about 3 kg with no issues. The print-in-place leg design is similar to a telescope, with all of the pieces sliding to the desired length and locking with a twist of a knob. What makes this option stand out when compared to traditional tripods is the scalability of 3D printing: It’s easy to change the height of the model should you want a taller or smaller tripod, just be sure to scale your hardware accordingly.

The Best 3D Printed Wind Turbines for Your Backyard

Imagine bringing the charm of Paris directly into your home with a modern, personalized touch. With Shadowbox Paris, you can do just that! This 3D printing model offers a fun and creative way to capture the essence of the City of Lights in elegant, detailed layers.

With just six layers, you’ll have a miniature of Paris’ most charming and romantic sights. Feel free to experiment with interesting and creative colors, but when choosing materials, think about where you plan to place the shadowbox. For example, heat from the sun may deform PLA prints, and prolonged UV exposure may have an adverse impact on the print.

Remember that the most important thing here is to make the first layer as perfect as possible. Depending on the surface of your table, the front side may reflect the texture of the build plate, and this can be a design feature for the piece. The print settings left by the designer indicate a layer height of 0.2 mm, two walls, and 10% infill.
