3-D Printing Parts for Knitting Machines

November 14, 2025

I recently started 3-D printing tools and replacement parts for some of my knitting machines and wanted to share the process in case it’s helpful. I had never printed anything before, but I knew my local library (the Cincinnati & Hamilton County Public Library) offered 3-D printing services and guidance. That was all the motivation I needed.

One of my patterns, the Carreau Top, uses a 1×2 needle arrangement. I wanted to use a pusher tool for my LK150 since it doesn’t have any automated patterning. I tried making a DIY version out of cardboard, but cutting precise little teeth was harder than I expected and the cardboard wasn’t durable at all.

Since the needle arrangement wasn’t too unusual, I figured someone might have already designed a file. I checked sites like Thingiverse and Printables for free open-source files and found 2×1 needle pushers for both standard gauge (4.5 mm) and mid-gauge (6.5 mm). I printed them both and they worked beautifully. It was such a relief not to manually move every third needle on the LK150.

That success got me thinking about the yarn guides on my Passap E6000. Mine had been broken and patched with duct tape for years 😔😂, and a 3-D printed replacement seemed like the perfect solution. I found another open-source file for the yarn guide, took it to the library and an hour and a half later the new guide was ready. At home I filed away a little excess material, wiped off the dust and installed it. The whole finishing process took under five minutes.

Here are two social media videos that show the process. My library only charges for materials, determined by the weight of the finished item. Each tool cost less than $2. Even in this economy!

I’m excited about what 3-D printing makes possible, especially for older machines where replacement parts can be hard to find. From tools to accessories or small repairs there’s a lot you can bring back to life with a simple print.

If you’re curious about trying it, check whether your local library or makerspace offers low-cost printing. Or make friends with someone who has a printer! It’s an affordable, fun way to keep your machine in good working order and keep your creativity moving.
