Project Space Princess – Utility Belt

Yes, I did actually make one for my daughter.

All heros, especially those of the Space Princess persuasion, need a solid utility belt.  Make one for the protagonist in your life… Or yourself… Those don’t have to be mutually exclusive.

Parts List:

1-1/2″ Lightweight Polypropylene – Strapworks (I bought 10′ of the stuff.  You won’t need that much, but it is so inexpensive I didn’t care.  Pick whatever color you want.  There are lots of options.)

1-1/2″ Plastic Slide – Strapworks (x1 if you want, but x2 for a cleaner-looking front.  We’ll follow the x2 version.)

Heavy Duty Snaps – Dritz (x1 package.  As the link would suggest, these were obtained from Joann’s)

Helpful Tools:

Measuring Tape


Snap-assembling tool (I got cheap and taped a few 1/4″ flat washers together)



  1. Print Out Parts

    Files can be found at Thingiverse, YouMagine, Cults3D, and MyMiniFactory.  Both sections of the buckle can print as one piece.  Model therefore is as such.

    4/11/2018 UPDATE:  Consolidating the number of places hosting the files.  More changes to come, but they’re still available for free.

    March 2020 UPDATE: Files can be downloaded directly from this site at the bottom of the page.  They are also available on Prusa Printers!

    The Prusa i3 Mk2s is so rad.

  2. Measurements

    Using the tape measure, wrap it around the waist of your subject.  Add around 12″ or more to that number.

    I... need to lose a few of those inches.

  3. Prep Belt Material

    Using scissors and a lighter, straight-cut the belt material to length, and melt the edge to prevent fraying.  Snip the corners off, and melt those as well.  Feel free to eyeball the corner cuts.

  4. Attach Snaps

    Center the “inside” snap pieces 1/2″ from the edges of the belt, and the “outside” snap pieces 2-1/2″ from the edges. Secure using your hammer and snap-assembling tool.

    Fabric tape measured are weird. There were like three different fonts on there.

    Same. Just flipped over.

  5. Slip in Slides

    Weave each end of the belt through the slides as shown.

    Corner snips showed up a bit late...

  6. Buckle Time

    “Frame” piece on the left, “Center” on the right.

    I don't know why, but I kept thinking this was more complicated than it was.

  7. Finish and Snap

    Weave the ends once again through the slides as shown.  Snap the snaps together.

    No wait, this was more complicated than I keep thinking.

    Now do that all again on the other side.

  8. Adjust and Suit Up

    Fit the “Center” component into the “Frame,” and adjust the slides to your most comfortable fitting.

    Yes. I am indeed a space princess.
