Notes
- 3060 aluminum extrusion, 8 mm slot (30-series): 30 × 60 mm, 6 slots on a 30 mm pitch (Misumi 6 series, 8 mm slot). Source: Misumi's dimensioned drawing of this profile. Files: STEP and STL at 100, 1000 mm with square ends, and a DXF of the exact cross-section (mm), the master to extrude to any length. The section is centred on the origin and extruded along +Z from z = 0.
- Slot: opening 8 mm, lip 2 mm thick at the opening, cavity 16.5 mm wide under the lips, 9 mm from the face to the cavity floor. Centre bore Ø6.8 mm per cell (the M8 tap drill).
- Cavity side walls: the drawing gives the cavity width (16.5 mm) and depths but not the web thickness, so the side walls run at 45° from the corner under each lip straight to the floor: the smallest cavity those numbers allow. The bar has at least the real metal there, and a part that fits this cavity fits the real one.
- The closed hollows between cells are not fully dimensioned on the drawing, so they are drawn filled: the outline, slots and bores are exact, the bar is heavier than the real one. The corner holes shown on the drawing are not fully dimensioned (no diameter or across-width spacing), so they are not drawn.
- Outer corners R2 (stated).
- Wrapping it: to make a part that fits around the bar, subtract the 1000 mm file (or extrude the DXF) from your solid; the outline is the drawing's 30 × 60 mm with no allowance, so open the pocket by your process's socket fit (see Mating features).
- Attachments: the 30-series (8 mm slot) T-nuts, end caps, feet, brackets, gussets, plates and slot covers are cut from these same numbers; the fit check (tools/asm_extrusion_fit.py) placed each one on this profile with zero overlap.

What is the slot size of 3060 extrusion?
Opening 8 mm, lip 2 mm, cavity 16.5 mm wide under the lips and 9 mm deep from the face to the floor, per Misumi 6 series, 8 mm slot's drawing.
What T-nuts fit 3060 extrusion?
The 30-series (8 mm slot) nuts: slide-in (tnut-slide-30-m5, tnut-slide-30-m6, tnut-slide-30-m8) and drop-in versions, threaded M5, M6, M8 as tap-drill holes, cut to this slot's exact space.
Can I subtract this file to make a part that fits the extrusion exactly?
Yes: the outline is exactly 30 × 60 mm with R2 corners; extrude the DXF or subtract the 1000 mm STEP, then open the pocket by your fit.
How heavy is 3060 extrusion?
1.6 kg/m, 592 mm² section, as Misumi states. This model's section is larger because closed hollows / cavity details the drawing leaves undimensioned are drawn filled; use the stated weight, not the model's volume.
What in this model is not taken straight from the drawing?
Cavity side walls: the drawing gives the cavity width (16.5 mm) and depths but not the web thickness, so the side walls run at 45° from the corner under each lip straight to the floor: the smallest cavity those numbers allow. The bar has at least the real metal there, and a part that fits this cavity fits the real one. The closed hollows between cells are not fully dimensioned on the drawing, so they are drawn filled: the outline, slots and bores are exact, the bar is heavier than the real one. The corner holes shown on the drawing are not fully dimensioned (no diameter or across-width spacing), so they are not drawn.
