Notes

  • 9090 aluminum extrusion, 10 mm slot (45-series): 90 × 90 mm, 8 slots on a 45 mm pitch (Misumi 8-45 series, 10 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 10 mm, lip 6 mm thick at the opening, cavity 20 mm wide under the lips, 13 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 (20 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 closed corner pockets (9 mm, 2.5 mm in) are not fully dimensioned and are drawn filled.
  • Outer corners R3 (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 90 × 90 mm with no allowance, so open the pocket by your process's socket fit (see Mating features).
  • Attachments: the 45-series (10 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.

Questions

What is the slot size of 9090 extrusion?

Opening 10 mm, lip 6 mm, cavity 20 mm wide under the lips and 13 mm deep from the face to the floor, per Misumi 8-45 series, 10 mm slot's drawing.

What T-nuts fit 9090 extrusion?

The 45-series (10 mm slot) nuts: slide-in (tnut-slide-45-m8) and drop-in versions, threaded 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 90 × 90 mm with R3 corners; extrude the DXF or subtract the 1000 mm STEP, then open the pocket by your fit.

How heavy is 9090 extrusion?

5.8 kg/m, 2162 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 (20 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 closed corner pockets (9 mm, 2.5 mm in) are not fully dimensioned and are drawn filled.
