I understand you're looking for a free plugin pack for SketchUp 2021. However, I need to provide some important guidance:

⚠️ The Warning: Avoid "Plugin Packs" from Unofficial Sources

If you search Google for "SketchUp plugin pack," you will likely find links to file-sharing sites (like Mediafire, Rapidgator, or torrent sites). We strongly recommend avoiding these.

1. Malware Risk: These packs are often executable files (.exe or .msi). SketchUp plugins should typically be Ruby scripts (.rbz files). executable installers from unverified sources can contain viruses, ransomware, or keyloggers.
2. Compatibility Issues: SketchUp 2021 runs on a specific version of Ruby. Installing old plugins from a "pack" can cause SketchUp to crash on startup or corrupt your model files.
3. Piracy: Many popular plugins (like Enscape or V-Ray) are paid software. Downloading them in a "pack" is illegal and unethical to the developers who create these tools.

3. Joint Push Pull (by Fredo6)

• Function: Extrude curved and non-planar surfaces.
• Why for 2021: Native Push/Pull fails on double-curved surfaces; this fixes that.

9. LayerWatcher (by Didier Bur)

• Function: Allows quick layer switching without opening the Layers panel.
• Why for 2021: Boosts workflow speed dramatically.

3. Eneroth Auto Mirror

• What it does: SketchUp removed the "Mirror" tool in older versions, and 2021 still relies on the "Flip Along" method which is slightly clunky.
• Why you need it: It adds a dedicated, intuitive mirror tool that works like other CAD software.

2. Artisan (Organic Toolset)

• Note: There is a free trial, but it is worth mentioning.
• What it does: Allows you to sculpt terrain and create organic shapes (like furniture or landscapes) that the native tools cannot handle easily.
