Where most listings are priced

Free shows the middle price. Pro also shades the range where the middle half of all listings sit, on the price ladder and on every category page. You see at a glance whether your 60% price is in the crowd or above it.

History back to January, not 7 days

You see every category's download curve, day by day, from our own daily checks starting 8 September. Older copies of the same MakerWorld page, saved by the Internet Archive, add history back to January where they exist. We do not fill in the days between saved copies. Enough to see a season start rather than a week of noise.

Planter, Etsy$17.76

Saved calculations and CSV

Give a calculation a name and come back to it from your account. Download the whole index as a CSV file, with the top models per category and all the history we hold. The three rows shown are this site's presets at their 60% price today.

What Pro changes

Everything else is free for everyone and stays that way: the calculator with presets and multi-plate products, the demand index, the top models per category and what buyers type. Every row below exists on the site today and links to where it is.

Questions

Where does the data come from?
Once a day we record the top 100 models per category on MakerWorld and Printables. Once a week we record the prices in Etsy search results for each category, using one hand-picked search term. From the same results we count how many are ads, on sale or offer free shipping. We also record what Etsy's search box suggests for each category, and Google Trends. Prices are in US dollars, the way Etsy's US search shows them. Nothing is estimated. If a source failed, the page says so.
Who runs this?
An independent operator in the EU. The legal name and address are published on the Terms page before purchases open.
Can I cancel?
Any time, from the account page, through Stripe. Access runs to the end of the period you paid for.
Can I get a refund?
Yes, in full, within 14 days of your first purchase, as long as you have not used a Pro-only feature yet. That is the EU right of withdrawal, and the Terms say exactly how it works. After that, a cancelled subscription runs to the end of the paid period and is not refunded.
Is the calculator going behind the paywall later?
No. The calculator stays free, including products made of several plates.
