Model Files & Releases

Coinfinity model files are distributed through controlled Google Drive links. This documentation is the source of truth for release notes, file naming, and which file set is current.

Do not upload STL or 3MF files directly to this GitHub documentation repository. Large binary files should stay in Google Drive so access can be managed, revoked, and audited without bloating the docs repo.

Current Release

Current release: TBD

Release date: TBD

Download folder: Google Drive link pending

Status: Current reseller release

Use this release for all new production unless Coinfinity provides written approval to use a newer preview build or older legacy file.

What’s Included

Each release should include the complete production file set for authorized resellers and licensed makers:

STL files for slicer-agnostic use
3MF files for prepared print profiles, where available
Product-specific notes for stackers, bins, lids, bases, and accessories
Any required print setting changes from the previous release

If a product is not included in the current release folder, do not assume an older file is still approved. Contact info@coinfinity.us before producing it.

File Naming Rules

Coinfinity model files use short product codes in the file name rather than semantic versions.

T = tube
C = cap
The middle number identifies the product size or family, such as 45.
The final segment identifies the release date, revision, or internal build code.

Examples:

T-45-02122026 = tube file for the 45 series, released or revised on 02122026
C-45-02122026 = cap file for the 45 series, released or revised on 02122026
T-45-xxx = tube file for the 45 series with a pending or internal revision code

Release notes should reference the exact file names included in the Google Drive folder. Do not rename files independently unless the release notes are updated at the same time.

- Cap files: `C-45-...`
- Bin files: `...`
- Base files: `...`

**Changed**

- Describe geometry, tolerance, printability, or compatibility changes.
- Mention whether the change affects existing inventory.

**Production Notes**

- List required slicer/profile/material changes.
- Call out any products that require special handling.

**Supersedes**

- Previous file set or specific file names

Access Control

Google Drive sharing should be limited to authorized reseller or licensed maker accounts. Do not use public, unlisted links for production files.

When access is removed from a reseller, remove their Drive access as well. The docs may describe the release history, but the actual STL and 3MF files should remain gated.

File Integrity

For important releases, Coinfinity may publish checksums for the release archive or individual files. This helps resellers confirm they downloaded the correct version and did not accidentally use a stale local copy.

Recommended checksum format:

SHA256  filename.stl  <checksum>
SHA256  filename.3mf  <checksum>

Checksums are optional for early releases, but recommended once reseller production volume increases.
