Prototypes (3D)

Prototypes (3D)

PLA · PETG prototypes for shape verification before CNC.

Small-batch (CNC)

Small-batch (CNC)

5–50 piece batches in aluminum · stainless. For shop inventory.

02 — How to quote

Quote process

CAD is optional. Photos and notes are enough to start.

  1. 01

    Upload drawing or photo

    CAD (DXF · STEP · PDF) is exact. Photos plus a quick sketch also work.

  2. 02

    Quote within 24 hours

    We send back material · process · per-quantity prices. Phone follow-up if needed.

  3. 03

    Confirm, build, ship

    3D 3–5 days · CNC 5–10 days. We share photos before shipping.

03 — Materials

Materials

We recommend the material that fits the use.

05 — Background

Technical background

5 yrs as a mechanic + certs and equipment specs.

5 years as a bicycle mechanic. Saw too many otherwise-fine bikes scrapped over a single discontinued part.

Set up the line in-house — three streams: discontinued parts · custom · small-batch.

No CAD? A photo and dimensions are enough to start: quote → prototype → batch.
