About ButterySpace

ButterySpace is an independent web tool that turns everyday images into files makers can actually print and cut. It requires no install and is built by the makers at DialUpDuo, who use it on their own products every week.

That's our little pat. It melts, then pulls itself back together. So do we.

01What we make

ButterySpace is a small toolkit. Drop in a photo, sketch, SVG, or STL and get back files that drop straight into the software makers already use:

  • 3D bookmarks. Upload an image and get a slicer ready bundle: a 3MF project file plus a matched single body STL, both in shared millimetre coordinates so they line up in mainstream slicers.
  • Rounded STL edges. Upload an STL and soften its sharp edges with a slider, so the print feels nicer in the hand and looks less blocky. Download a smoothed STL, ready to slice.
  • Clean SVGs. Convert an image to a vector that imports cleanly into Cricut Design Space, Silhouette Studio, Glowforge, LightBurn, Illustrator, and Inkscape.
  • Color Book pages and reliefs. Turn a drawing into a clean coloring page and a 3D relief tile. Print the relief in one solid color, then color it in by hand, both between the raised lines and over the lines themselves.
  • Lithophanes. Turn a photo into a backlit-ready lithophane panel, flat or curved, delivered as a 3MF plus a matched STL that ship already standing in the print orientation.
  • An SVG file doctor. Paste in an SVG that a cutter rejects and we flag the machine-specific traps (missing canvas size, stroked outlines, embedded photos, unsupported effects) that make a technically valid file fail on import.
  • Format conversion. Convert the HEIC photos your phone takes into the PNG or JPG that maker software actually accepts.

The whole point is that you should not need Illustrator, Inkscape, or a CAD seat to get a clean, maker ready file. Drop it in, convert, download.

02Who builds it

ButterySpace is built by Jesse, one half of DialUpDuo (opens in a new tab), a small independent studio. There is no big company behind it. It is a focused tool made by people who design, print, and tinker, and who got tired of fighting file formats before every project.

The honest origin story: we did not set out to make a converter for other people. We built it for ourselves. DialUpDuo makes and sells its own products, and we kept hitting the same wall, over and over: an image that would not trace cleanly, an STL with edges too sharp to hold, an export that loaded at the wrong scale. So we built the tool we needed, used it on our own work, and then opened it up because every other maker we knew was fighting the same files.

We still use ButterySpace every week to make the things we sell on our own two Bambu Lab X1C printers. That hands-on work shapes the tools and the parts of our guides that describe our own results. Because we are small, the roadmap is shaped directly by the people who use the tool. The fastest way to reach us, suggest a feature, or report something broken is the contact page or our Discord community (opens in a new tab).

03What we commit to

  • Your files are yours. We process the image you upload, return the result, and delete the files automatically. By default they live at most 24 hours on Cloudflare R2, then they are gone. See the Privacy Policy for the full detail.
  • Never sold. We do not sell your images or use them to train third-party AI models. There is an entirely optional product improvement opt-in, explained in the privacy policy, that lets us keep a session's files for up to 30 days and use them to improve our own algorithms. The tool works exactly the same whether you join it or not.
  • Honest about limits. We tell you what the tool does and does not do, in the guides and on the tool itself, rather than over-promising.

04How we publish guides

Guides are published under the ButterySpace name because they can combine our product documentation, established maker practices, outside research, and notes from our own projects. We do not attach one person's name to every article when that would imply they personally tested every claim.

  • Hands-on claims are specific. When we say we printed, measured, or used something ourselves, the guide should say what we tested and show the available source, screen recording, sample file, or real-world photo.
  • Starting points are not lab results. Settings and compatibility advice are labeled as practical defaults when they have not been tested as a controlled comparison across machines and materials.
  • Limits stay visible. Tool demonstrations show what happens on screen; they do not stand in for a finished physical print. Affiliate links are disclosed and do not change the recommendation.
  • Updates mean something changed. We add an updated date only after a substantive correction, clearer evidence, or a meaningful change to the workflow.

Found a claim that needs correction or a result we should test? Tell us. We would rather revise a guide than leave an overconfident answer online.

05Learn and explore

We publish practical, maker-focused guides on the things that actually trip people up: why a valid SVG still fails in Cricut, print settings for 3D bookmarks, adding color in Bambu Studio, STL versus 3MF, and more. Browse them on the Guides page, or jump straight into the tool.
