How recorded activity is shared

The top 1% account for 45.8% of recorded downloads in this sample. The bottom half account for 1.7%.

Activity	Listings sampled	Top 1% share	Top 10% share	Bottom 50% share
downloads	231,525	45.8%	80.7%	1.7%
prints	231,525	50.6%	84.3%	0.9%
likes	231,525	40.1%	78.5%	2.4%

Each row ranks listings by that activity. Groups overlap: the top 1% is included in the top 10%.

Use several examples when researching an idea. A single popular listing may be unusual.

Compare categories before choosing a project

Start with a category relevant to your idea. Compare its observed average with the sample, then look at individual designs to understand what people are downloading.

For each listing, lifetime downloads are divided by age in whole days, with a minimum of one day. We then average those values. This is not downloads gained yesterday. A few popular listings can pull the average up; age, creator audience and promotion can also explain differences.

Category	Listings sampled	Lifetime daily average	Relative to sample
Household	57,576	0.39	0.96×
Hobby & DIY	34,815	0.32	0.79×
Art	30,863	0.22	0.56×
Tools	28,615	0.42	1.05×
Decor	27,937	0.40	0.98×

1× equals the average across all 231,525 sampled listings. Categories include at least 500 listings and are ordered by sample size. Listings can belong to more than one category; row counts should not be added together.

Use this to choose what to research next. A higher average does not establish an underserved market or predict downloads for your design. Downloads do not measure demand for paid prints.

What is being published now

Subjects that appear most often among the 28,162 sampled listings observed at 7–90 days old, ordered by how many listings carry each tag. Use the count to see how many creators are already publishing a subject, and the observed spread and examples to study how those listings are presented.

Each listing counts once per subject. Lifetime prints per day divides a listing’s saved print total by its age in whole days; it is not recent growth or unmet demand. Print time and filament are the slicer estimates saved on each listing’s default print profile. A subject needs at least 30 recorded print counts from 15 known creators; subjects overlapping more than 80% with a larger one are omitted, as are platform, material and descriptive tags. Examples are chosen by age and creator variety, not by performance.

A frequent subject shows where creators are already publishing, not where demand is unmet. Subjects overlap and differ in age, audience and exposure. Read several examples before deciding what to make.

Effort61 categories · default print profile

Print time and filament by category

How long the listings in each category take to print and how much filament they use, from the slicer estimate saved on each listing’s default print profile. Use it to gauge the effort and material cost typical of a category before committing to a design or a print run.

Category	Listings with an estimate	Median print time	Middle half	An hour or less	More than 8 hours	Median filament
All sampled listings	202,015 of 231,525	2 h 6 min	55 min – 4 h 44 min	27.3%	13.1%	43 g

Hobby & DIY	29,371 of 34,815	1 h 38 min	43 min – 3 h 56 min	34.9%	10.8%	35 g

Decor	25,866 of 27,937	2 h 43 min	1 h 19 min – 5 h 36 min	17.5%	15.4%	63 g

Estimates describe the profile the creator published as the default, sliced on their settings and printer. They do not cover every file in a listing, your printer’s speed, or failed prints. Listings without a saved estimate are excluded from the medians. A spread needs at least 30 estimates.

Crowding61 categories

How crowded each category is

How many creators publish in each category, and how much of its recorded activity sits with a few of them. A category where ten creators hold most recorded downloads behaves differently from one spread across many.

Category	Listings	Creators	Recorded downloads held by its 10 most-downloaded creators	Listings from creators with 5+ listings here
Household	57,576	31,564	7.5%	31.5%
Hobby & DIY	34,815	25,218	9.8%	12.7%
Art	30,863	15,540	12.7%	38.8%
Tools	28,615	21,179	9.4%	11.2%
Decor	27,937	14,242	8.3%	37.1%

Creators are counted where the listing names one; the repeat-creator share uses those listings as its base. Download shares use lifetime totals over listings of every age, so long-standing creators weigh more. Concentration describes the sample as observed; it does not say whether a newcomer can or cannot get downloads there.
