Biggest opportunity: “3d”, “3d printing” and “shortcode” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active
At least 100 of 8.3K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,768 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
High removal-risk signals
63/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 11+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 4.1.42, well behind 6.8.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

Directory rank
Ranked about #13,300 to #16,400, alongside the other plugins at 100+ installs. Plugins with the same install count swap places between wp.org requests, so this is where most of them sit. Checked monthly, last on 21 Oct 2026.
Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence

Only one but: but it would be nice if Settings, Rendering Options and Lightning Option would be explained
Read on wp.org ↗ - ★★★★★ AAA11.0y ago
… but needs some config. 1. Enable .stl file upload (or any other file type or file-extension) You have to disable FILTER upload before be able to upload an .STL file. Just add // -- allow all files to be uploaded define('ALLOW_UNFILTERED_UPLOADS', true); somewhere in your config.php file. 2. Refer your .STL files correctly Then make sure you refer your .STL files correctly! If your domain is: http://www.yourdomain.com Your uploads will go to maybe: http://www.yourdomain.com/uploads/2015/10/myfile.stl So refer the stl file as: /2015/10/myfile.stl because http://www.yourdomain.com/uploads/ is added by the plugin itself. 3. Example: Insert code is not documented within the plugin, which is a shame. So here it is: [stl file="/2015/10/3dprinted-wrench.stl" /] Hope that helps. 4. Setup Background I was not able to set the background, which seems to be just a black color by default. There is a way within the plugin to setup a tile (image) but it did not work correctly. (Just a small stripe is shown.) I did try: [stl file="myfile.stl" background="#f8f8f8" /] but does not seems to work for me. Question If someone knows how to setup Background color (mono, fix), or tile image, please let me know! This topic was modified 4 years, 4 months ago by AAA.

This was very easy to setup. I had an issue with the STL-Viewer plugin settings not working, so I simply passed all the setting parameters within the shortcode. Then I published my page and now everything looks terrific. I am really impressed with how good the renderings are and how quickly the files load. Still slow for the larger STL files, but the plugin caches the files. Shortcode Example: [stl file=”Army_Dude.stl” color=”#ff0000″ background=”#f8f8f8″ width=”100%” height=”640px” /]

Great plugin, works amazing Tip- after activation make sure go to the plugin settings and fill the boxes else it won’t display a thing. Suggestion – and i would love to see these in settings – if we can change the default file location – remove the grid – auto rotate for all the objects by default – select the axis for all the object as by defualt ( and a command if any object need to be on diffrent axis ) 🙂
