We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

Good to know before you order

TPU has a £11.50 print-order minimum. ABS, ASA, PC, Nylon and PETG-CF have a £46 minimum; PA-CF has a £69 minimum. Delivery is shown separately in your cart.

Need a few parts? Add them to one cart. One order minimum and one postage charge cover the cart: £6.90 for standard materials, £11.50 with TPU, £46 with ABS, ASA, PC, Nylon or PETG-CF, or £69 with PA-CF.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

About this print

A print-in-place balisong, commonly known as a butterfly knife, designed as a trainer and fidget toy rather than a functional blade. The model prints as a single piece with all moving parts already connected, making it suitable for cosplay props or desk fidgeting. PLA is a practical choice for this model, as the print-in-place mechanism relies on precise layer clearances that PLA handles reliably at standard settings.

This print was a request from someone, I figured why the heck not?

I honestly learned a lot through the design and print of this one about clearance dimensions required for 3D printing without having the layers stick together between parts I didn't want stuck together.

Another lesson learned was that a model can be designed as an assembly, then exported to a single file for print. (3MF worked without issues, but STL scaled improperly although all the settings were correct. I ended up scaling up the model before exporting to STL so it would be the right size). Oh the Joys...

This thing is wicked fun! It's not going to carve a speartip on a stick but it is great to fidget with and enjoy while impressing everyone you show it to.

Best thing is that you just click print and ~6hrs later (ender 3) a functional assembly (without assembly) comes off the print bed.

I made these 4 from PLA materials, and all work flawlessly. Interested in seeing what materials you print with to share!

The YouTube video has a lot of instruction and background to this project as well, it's linked above so just give it a watch if you want to see more about it (such as the print orientation it is designed for).

I hope you enjoy! Thanks for checking it out! If you like things like this be sure to check out the many other models I have here.

If you're looking for a locking handle version of this butterfly knife, I made a recent update. Check out the updated model below:

Printing Butterfly Knife - Print in Place - (Balisong)

For Butterfly Knife - Print in Place - (Balisong) we would normally reach for PLA, or resin for the finest detail — PLA captures detail cheaply, and resin is an option where the very finest features matter. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
