Choosing your first dollhouse STL: a download checklist

Print your furniture · All guides in this chapter

A first printable miniature is really two purchases: a design you like and a file that suits your printer. The second part is easy to overlook. A model can look perfect in its photographs and still be a poor first project if it needs dense supports, exists only at a scale you do not use, or was never intended for your printing process.

This checklist works with any shop’s files. We use Cabinet Douze pieces as examples because we can state exactly what their packs contain and how they were checked.

Check what the download contains

A digital listing sends files, not an object. Before buying, look for three facts: the file formats, the scales supplied and the licence.

Cabinet Douze packs contain an STL and a 3MF for every scale listed on the piece page. STL is the most widely supported mesh format; 3MF can carry additional information and opens directly in current slicers. Both describe the same shape. The files are for personal printing under our licence; the Etsy listing shows the current price and delivers the download after purchase.

If a listing does not name its scales, ask before buying or assume you will need to resize. A “1:12 and 1:24” pack contains two separate files. A single file with a note saying “scale to 50% for 1:24” is a resizing instruction, not a second tested size.

Check the scale and the footprint

Choose the scale of your room first, then check that the pack actually includes it. On 29 September 2026, 127 of our 133 single designs include both 1:12 and 1:24; 21 also include 1:6. Some do not: the Mid-Century Credenza is supplied at 1:12 only. Its piece page lists 1:12 alone, which is the scale you can buy with confidence.

Then compare the footprint with your room. Width and depth decide whether the piece fits the floor; height decides whether it clears a sloping ceiling, a window or a shelf above. Use the measured dimensions on the piece page and check the piece will fit beside the furniture you already own. If your reference is a full-size measurement, the scale calculator converts it in one step.

Check the process: resin or FDM

Resin printers cure thin layers of liquid resin and reproduce fine detail well. FDM printers extrude melted filament; they are common and affordable, but a nozzle cannot draw a feature narrower than its line width. Some miniatures work on both, some on one.

Every Cabinet Douze piece page states the processes separately. Resin is the default for all our designs. FDM appears with the scales our automated checks passed for that process. On 29 September 2026, 127 single designs list FDM, and 30 of those pass at some supplied scales but not others. The Mid-Century Lounge Chair, for example, passes the FDM checks at 1:12 and 1:6 but not at 1:24; at that scale, resin is the process our checks support.

These are digital checks on the delivered geometry, not physical test prints. Use them to rule a file in or out, then inspect the sliced layers with your own printer profile.

Check supports and parts

Supports hold overhanging surfaces while the print is built. They must be removed afterwards and can mark the surface they touch. Our pages use three labels: no supports needed, light supports and heavy supports. Of our 133 single designs, 5 need none, 21 light supports and 107 heavy supports. Heavy is common for furniture with legs, arms and open undersides; it is not a warning, but it is more work.

Count the parts too. A single-part design avoids gluing and alignment; a set or kit asks you to assemble several prints. All our single designs print as one piece, while bundles contain several pieces.

A sensible first print

For a first file, look for a compact, closed shape with a flat base, one part and few overhangs, at a scale your process passed. Two examples in our catalogue meet all of those conditions:

• Coastal Dining Sideboard With Central Drawers: one part, no supports needed, FDM checks passed with warnings at 1:12 and 1:24, 150 mm wide at 1:12.
• Gothic Tall Closed Pantry Cupboard: one part, no supports needed, FDM checks passed with warnings at both supplied scales.

Keep a heavily supported chair, a turned-leg table or an openwork piece for your second or third print, once you know how your printer handles overhangs and small features. The design you love most will benefit from that experience.

Before and after you download

Before buying, read the listing on Etsy: it is the authority for price, files and licence. After downloading, open the file in your slicer and confirm its dimensions match the piece page. Then follow the preparation steps in how to 3D print dollhouse furniture: orient the part, add the supports it needs and inspect every layer that contains fine detail.

Keep a short note of the file, scale, process and printer profile you used. If the first print needs changes, you will know exactly what to adjust next time.
