The Top STL Files of 2023

As we look back on a year of impressive, helpful, wacky, and fun 3D printing experiences, we can’t help but pick out some of our favorite 2023 STLs and highlight them in our end-of-year retrospective. From giant 3D printed constructions to tiny creations, the 3D printing makers have been putting in the work to bring unique designs and reimagined 3D printed classics into reality with the help of some filament and elbow grease. We’ve made sure to stop by some of the big names in STL databases like Cults, Thingiverse, Printables, and even MakerWorld, who made their debut this year, to gather some of the most popular, most striking, and most helpful STL files of 2023 to share with you! 

3D Print This Remote-Controlled Airliner

We start this year’s ranking off with a high-flyer – a fully functional CRJ Series drone! This incredible two-meter-long (6’5″) aircraft is fully 3D printed! As if the fact that it is capable of flying were not enough, it has retractable landing gear and moving flaps to improve the aircraft’s maneuverability and realism. The model we chose as part of our top STL files of 2023 is the CRJ 900, although it is possible to print the CRJ 700 with this same file simply by removing a piece of the design. That’s two drones in a single STL file! Going into more detail about the printing process, it takes a little more than 120 hours to print all the parts. Assembly is relatively straightforward and it uses about 3.3 kg (7.3 lbs) of PLA material or 2.3 kg (4.4 lbs) of LW-PLA to make the entire kit.

Customize Your Phone With This 3D Printed LEGO Case

We move on to a 2023 STL file that is both practical and unique. Check out this cellphone case that can be customized in the most creative way imaginable. This 3D printed LEGO cell phone case not only mimics the look of the classic toy, but the studs that stick out along its surface are the exact shape and size of LEGO blocks, allowing users to unleash all their creativity and attach LEGO pieces to the case to create custom designs. This specific case is designed for the iPhone 13, 13 Pro, as well as the iPhone 14 and 14 Pro. The case is printed in three separate parts and there is no need for supports, making the printing process even easier to create, assemble, and use. It is recommended to print this iPhone case with TPU, although you can also use TPE, which gives the case a nice soft feel. Download the STL file and 3D print your case at home by clicking HERE!

An Impressive Oni Mask STL

This next STL file for 2023 will transport you back to ancient Japan as user PIPE_COX from cults3D shares a very detailed Oni mask! This mask was used to represent demons (Oni) in Japan, but today they are an international fashion statement for many brands, whether on T-shirts, in video games, or in art exhibitions. With this STL file, you can print your own Oni mask at home and use it for decoration or as a costume. The file includes two different versions of the mask, so you can make it as you like. The full-scale mask is a perfect fit for a 165mm (6.5in) wide head, and from there you can scale the print down so it can fit any sized head. The creator recommends using tree supports in the printing process to ensure the quality of the print. The best thing about this mask besides its detail is that the printing time is short and the file can be downloaded in STL and multicolor 3MF formats. Don’t miss out on your very own and download it HERE.

Prize Winning 3D Printed Hex Grid Storage Wall

The first prize winner of the “Wall Hooks” 2023 STL file contest on Printables, this practical creation will help you keep your tools, study, or work objects perfectly organized. It is a wall-mounted design that can be 3D printed to maximize your storage space, with a honeycomb structure that makes it firm and resistant. The designer, user RostaP, has made the best use of this structure’s design by creating small hexagonal-shaped molds to fit inside the cells of the honeycomb. In this way, they have managed to create various forms of support that allow you to attach almost any object to the wall – it even has an attachment for microSD cards! It is also quick to print, so that in just under 4 hours you can have all the pieces printed and begin assembly. So, do you need some more space? Download this STL file HERE!

A 2023 STL for All Your Star Wars Needs

Whether you’re a fan of the show, into cosplay, or just like the letter ‘T’, the Star Wars Mandalorian helmet is the perfect piece of kit for any true fan of the Star Wars universe. This particular model, coming to us from user m.cody.sims on the fledgling Bambu Lab STL site, MakerWorld, is interesting for several reasons. Despite the relatively young age of MakerWorld, which is still in beta at the time of writing, this Mando design has shot to the top of the list of most popular designs, sparking a collaborative conversation in the comments as users show off their prints and give tips and tricks where needed to new users who are interested in printing their own. Able to be printed in a variety of colors and assorted filaments, this is one design that allows for a great deal of customization and personalization. We may not be able to print with Beskar in our universe, but regardless of the material used, this is the way.

A Highly-Detailed, Miniature RC Tugboat STL for The Perfect 2023 Project

For those who like building models, working machines, or assembling a complex project from scratch, look no further than this meticulously crafted 3D creation from user HALLER3D. This 1:75 scale model of a tugboat is not only surprisingly detailed and well-designed, but also is capable of being remote control operated to give trips to the park or lake a much more exciting twist as you get to see your very own creation take to the water. One thing to note is that the designer themselves has warned that the design is for experienced modelers only, a point backed up by the price tag of the files themselves.
