A designer published SCeAR22 version 1.0, a printable .22-caliber build. The notes credit Kruscle for the concept, unnamed beta testers for trial parts and comments, Ciwielab for an M7 lower used as the starting point, and RG3D for a stock or brace included because it matched the design.

Renders show the pack with Proof backup iron sights, a DB Tailgunner grip, Foaps HK-style sights, a Grixxlyprints modular muzzle, and a Blagotago Nomad suppressor at the maximum width the SD version is meant to use. The author asked people to share finished prints and to send comments or Matrix messages to the listed account.

The files note that print orientation can be chosen for strength on a .22, with 300BLKFDE slicer settings and PLA Plus or PLA Pro as the minimum material.
