What is the Digital STL Fixed-Length Rear Shock Dummy and what does it include?

The Digital STL Fixed-Length Rear Shock Dummy is a downloadable STL file you print at home to create a fixed-length placeholder for your mountain bike's rear shock. You receive one STL file matched to the exact length and mount configuration you select — covering Standard Eyelet (M10) lengths of 190, 210, 230, and 250 mm, and Trunnion lengths of 165, 185, 205, and 225 mm. It is for maintenance, transport, and storage only — not a riding component.

Which mount configurations does the Fixed-Length Rear Shock Dummy STL support?

The STL covers seven mount configurations: Straight, Yoked, 10° Offset (Eyelet), Normal Trunnion, Yoked Trunnion, Yoke Crooked Trunnion, and the 15 mm Giant version. This includes compatibility with most diagonal and non-parallel trunnion mount orientations, making it suitable for a wide range of modern mountain bike frames.

How does the Digital STL Fixed-Length Rear Shock Dummy differ from buying the physical printed tool?

The STL download delivers the same geometry as the physical tool — fully tested on real bikes — but you print it yourself, eliminating shipping cost and lead time. It is the lower-cost, lower-footprint option suited to riders who already own a 3D printer and need only a single specific size. The physical product suits riders who prefer a ready-to-use part without printing.

What 3D printing settings are recommended for the Fixed-Length Rear Shock Dummy STL?

Shockwave Parts recommends PETG as the standard material (Nylon for heavy use), a 0.4 mm nozzle at 0.20 mm layer height with 5 walls and 60% infill — no supports required. A 0.6 mm nozzle also works using 0.3 mm layer height, 4 walls, and 40% infill. Trunnion threads are intentionally printed with light engagement; they only need to catch the bolts and will not pull out during normal maintenance.

What are the license terms for the Fixed-Length Rear Shock Dummy STL file?

The file is sold under a personal-use license: you may print unlimited copies for yourself, and printing for friends is permitted. Reselling the file or the printed part is not allowed. Shockwave Parts asks users who print for others to consider a small donation via buymeacoffee.com/shockwaveparts to support continued development.
