Massively complicated print jobs that need 48 hours to complete? Forget about it! Here are 20 fun things to 3D print in an hour (or less).

We’re all busy people. Sometimes we haven’t the time to wait for days and days before a print job is finished. And worse still if the print job gets all futzed up at the eleventh hour, and you have to start all over again.

No. Sometimes, we just want to print something just for fun, something which won’t take longer than an hour. Here are 14 fun things to print that are so simple, they’ll be finished in 60 minutes or less.

These timings have been checked for accuracy on an Original Prusa i3 MK3, but keep in mind that some 3D printers will perform faster than others, and you’ll probably have tweaked your machine for your own optimal speeds and settings.

To stay within our self-imposed parameters, the majority of these items should be printed at 200 microns with 20% infill, except where specified otherwise.

Fun Things to 3D Print in 5 Easy Steps

  1. Browse this list of fun things to 3D print for inspiration and ideas. Go ahead, take your time, we’ll be here when you get back.
  2. Download the STL file for your chosen model. Click on the link to take you to the site where the files are hosted, and you can download them absolutely free. Please note that some sites may require registration before you can download.
  3. Slice the STL file to prepare it for 3D printing. Whether you use an open source application like Cura or a paid solution like Simplify3D, slicing is a critical step for the quality of your model. Open the STL file and tinker with settings like infill, layer height, and supports.
  4. Convert the STL file into GCode after you’re done slicing. Save the GCode and upload it to your 3D printer, either using a USB cable, an SD card, or a network connection. Now get printing!
  5. Alternatively, use a Service if you don’t have access to a 3D printer. Simply upload the STL files to All3DP’s Best Price 3D Printing Service to have any of these cool things 3D printed.

Fun Things to 3D Print in an Hour (or Less) Flexi Rex

Image of Fun Things to 3D Print in an Hour (or Less): Flexi Rex

Flexi Rex has a convoluted history. He was originally conceived as a drop-in enhancement for the legendary board-game “Settlers of Catan”. Designed by Zheng3, the original Robber Rex was a humorous little model. Now through a series of remixes, we have the Flexi Rex, which adds links to make him bendable, posable. You can also print Flexi Rex in two colors using a dual-extrusion 3D printer, though that will lengthen your production times.

Fun Things to 3D Print in an Hour (or Less) Proteus Key Holder

Image of Fun Things to 3D Print in an Hour (or Less): Proteus Key Holder

This is a key holder in the style of a Swiss Army penknife. Simply print each half and then assemble together with your keys using a set of nuts and bolts. For this particular project, it’s recommended that you raise the infill to 75% minimum. That will increase the print time past the 1 hour threshold we’ve set ourselves, but you can definitely fabricate a sample model with lower infill in under an hour.

The jolly 3D printing torture test is totally worthy of inclusion here. Not only is it a pretty little steamboat, it’s also been carefully designed to test and calibrate the settings on your 3D printer. We’re literally drowning in them here at ALL3DP, because they’re so reliable for quickly assessing the capabilities of the 3D printers that come into our workshop for review.

Make some noooooooize with this 3D printed whistle. It emits a pitch of 118db! Suitable for use by lifeguards, traffic cops, school teachers, and party animals. It takes about an hour and a half printed with the recommended 100% infill at 200 microns. But you can further reduce the print time by printing it at 300 microns instead.

Fun Things to 3D Print in an Hour (or Less) Strong Carabiner

Image of Fun Things to 3D Print in an Hour (or Less): Strong Carabiner

This is a ultra useful item to 3D print, a carabiner with a strong frame and a flex door design which uses a split hinge to open and close. It prints quick and easy with no supports; simply arrange two items on the single build tray. But while this carabiner is capable of carrying loads of up to 30kg, it’s not suitable for use in activities such as climbing. Absolutely no way should you even think about doing that.

Fun Things to 3D Print in an Hour (or Less) Micro Catapult

Image of Fun Things to 3D Print in an Hour (or Less): Micro Catapult

This is a great little toy for the office or classroom; a print-in-place micro catapult which can lob tiny nuggets of ammo. The maker reckons it can hit targets up to two meters away. The smart feature is that you can lock the catapult in place until you’ve loaded it up and are ready to fire. The “spring” mechanism relies on the flexibility of the material. In those terms, a less brittle filament like ABS or PETG is most suitable.

Fun Things to 3D Print in an Hour (or Less) Credit Card Cutlery

Let’s imagine you want to spontaneously chow down on a big plate of currywurst and chips. No cutlery? No problem, whip out these credit card sized utensils from your wallet, press out the knife and fork, and enjoy your meal. Also comes with a spork variation, so you have all your bases covered.

Standard caveats about 3D printing and food apply. Firstly, fabricate with a non-toxic filament like PLA or PETG to avoid contaminating your food. Secondly, this is an item designed for single use only. Microbes have a habit of getting stuck in the tiny crevices between layers.
