#prusa #nextruder #nozzle #packaging #storage # Nextruder Nozzle Case Part Numbers The clear square sleeve Prusa Nextruder nozzles ship in is **not** a Prusa part. It's a stock **Cleartec Packaging "Grip Pak," GRP 08 series** (Cleartec = a division of MOCAP; their China arm Beckett almost certainly supplies Prusa). | Component | Part # | Spec | |---|---|---| | Clear tube | `GRPF080079` | 12.8 mm sq head, 72.6 mm tube, fits 3" tool | | Base plug | `GRPM080003` | 3.0 mm shank bore, 11.0 mm inside width | Measured OEM sample: 12.78 mm sq × 83 mm total, 73 mm clear tube, 20 mm cap (10 mm inserted), grips the 2.93 mm nozzle tip. Exact match. The `08` is a family designator, not a dimension — don't search on "8 mm." ## Buying empties - **Small qty** — [Cleartec's own store](https://store.cleartecpackaging.com/clear_en/grp.html?Item=GRPM080003L07&To_Fit_Shank_Diameter=0.11811&Inside_Width=0.43307&Material=LPBLUEMID) sells Box/Mini/**Micro** tiers of 1000 / 200 / **20**.
