DIY Dollhouse Gym Accessories: Everything I Made

My dollhouse gym was the first room I built, and it ended up teaching me more than any other room in the house. It is a 1:12 scale space packed with equipment and small personal touches, eleven pieces in total. Here is every single one, in the order I actually built them, so you can pin your favorites or follow along piece by piece.

1. Magazines

I designed custom magazine covers using my own Canva magazine template and printed them on cardstock, scaled down to 1:12.

Starting with the magazines instead of the furniture gave me a color palette to build the rest of the room around. It is a small reversal of the usual order, but designing the print pieces first made every material choice after that a lot easier.

2. Magazine Rack

To hold the magazines, I built a wall mounted display rack out of balsa wood sticks, cut to size and assembled by hand. I wrote up the full process, with measurements and steps, in this magazine rack tutorial.

Balsa is forgiving to cut and glues cleanly, which made this a good early build. Mounting it to the wall instead of setting it on a shelf also gave the room its first sense of real dimension.

3. Yeti Tumbler

I modeled and 3D printed a mini Yeti tumbler after my own, matching its shape and proportions down to the small details.

Working from an object sitting right on my desk made this one of the easiest pieces to get right. When you are not sure a miniature reads as the real thing, printing or building it next to its full sized counterpart is the fastest way to check your scale.

4. Yoga Mat

The yoga mat is craft foam, cut to size and rolled or laid flat depending on how I am styling the room that week.

Craft foam has just enough thickness to read as a real mat without looking bulky at 1:12 scale, and it is one of the cheapest materials in this whole build. It is a good reminder that not every piece needs to be 3D printed to look convincing.

5. Poster

I 3D printed the frame, then designed the artwork itself in Canva. The version pictured says “Baby Got Back,” but I also made “Harder, Better, Faster, Stronger” and “You Can Do It, Put Your Back Into It” versions.

Letting the poster text be a little funny is what makes this room feel like my gym and not a generic dollhouse gym. If you build one of these, do not be afraid to make the artwork personal instead of decorative.

6. Race Bib Display

This piece means the most to me. I scaled down my own real race bibs in Canva, printed them on cardstock, and attached them with jump rings to a metal chain.

It is a reminder that I can do hard things, shrunk down to fit on a dollhouse wall. If you have a personal object like this, a race bib, a ticket stub, a medal, it is worth finding a way to bring it into your build instead of using a generic prop.

7. Faux Potted Plant

The planter is 3D printed from this tall planter STL file, filled with greenery from the craft store and soil made using the same coffee grounds method I used on my porch build.

Reusing a technique I had already tested elsewhere in the house saved me a round of trial and error, and it kept the soil texture consistent from room to room. If a trick worked once, there is no reason not to use it again.

8. Dumbbells

I modeled and printed a full dumbbell set in 3, 5, 7, and 9 lb sizes. Each one is hand painted with a metallic silver head, and I left the indented weight number in black so it stays legible at scale. The STL file is available here if you want to print your own.

Painting the numbers a contrasting color instead of leaving them silver on silver is what makes them readable up close. It is a small step, but it is the difference between a prop and a piece that holds up to a photo.

9. Weight Rack

I designed a weight rack with the shelves set at a slight slant to hold the dumbbells. The STL file is available here.

The slant is a small detail, barely a few degrees, but it is what makes the rack read as gym equipment instead of a generic shelf. Sometimes the smallest deviation from a straight line is what sells the realism.

10. Workout Bench

No home gym is complete without a bench, so this piece was non negotiable. It anchors the room and gives every other piece something to be scaled against. The STL file is available as part of my Miniature Home Gym Bundle.

I built this one later in the process on purpose. Once the smaller pieces were finished, I had a much better sense of exactly how big the bench needed to be to keep the whole room proportional.

11. Arched Mirror

I 3D printed a 3 x 5.5 inch arched mirror frame and cut the mirror itself from these mirror sheets. The frame STL is included in the Miniature Home Gym Bundle.

Cutting the arch shape out of mirror sheeting by hand took patience and a steady blade, but it is what gives the room that polished, boutique gym feel instead of looking flat. Save this piece for last. By the time I got to it, I had enough practice with fine detail work to get the curve right on the first try.

Bringing It All Together

Eleven pieces is a lot for one tiny room, but that is what it took to make this gym feel like an actual reflection of my own workout space instead of a generic dollhouse room. If you want the full play by play, I go deeper on the equipment in Everything I 3D Printed for My Dollhouse Home Gym and the decor in Dollhouse Gym Decor: Adding Personality to My Miniature Home Gym. Most of the 3D printed pieces here are also available as STL files in my STL Shop or as hand finished pieces in my Physical Exclusive Drops shop, so you do not have to start from scratch.

Save your favorite piece and let me know which one you are building first.
