Notes
- 1010 T-slot extrusion, 1 × 1 in (10-series inch): 1 × 1 in, 4 slots on a 1.000 in = 25.400 mm pitch (80/20 Inc. 10 series (1 in)). Source: 80/20'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 0.256 in = 6.502 mm, lip 0.087 in = 2.210 mm thick at the opening under a 2° drop-lock slope (0.093 in = 2.355 mm at the cavity wall), cavity 0.584 in = 14.834 mm wide under the lips, 0.323 in = 8.204 mm from the face to the cavity floor. Centre bore Ø0.205 in = 5.207 mm per cell (the largest thread whose tap drill fits inside: 1/4-20, 5.1 mm).
- Cavity side walls: the cavity is 0.584 in = 14.834 mm wide under the lips, then follows the diagonal webs (0.087 in = 2.210 mm thick, stated) down to the floor; the webs lie on the cell diagonals (45°), as drawn.
- The drawing does not dimension the outer corner radii, so the corners are square: a pocket cut from this file clears the real rounded corners. The small alignment grooves on the faces are not dimensioned and are left off (the faces are flat).
- 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 1 × 1 in with no allowance, so open the pocket by your process's socket fit (see Mating features).
- Attachments: the 1 in 10-series 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 1010 extrusion?
Opening 0.256 in = 6.502 mm, lip 0.087 in = 2.210 mm, cavity 0.584 in = 14.834 mm wide under the lips and 0.323 in = 8.204 mm deep from the face to the floor, per 80/20 Inc. 10 series (1 in)'s drawing.
What T-nuts fit 1010 extrusion?
The 1 in 10-series nuts: slide-in (tnut-slide-10in-1-4-20, tnut-slide-10in-10-32) and drop-in versions, threaded 1/4-20, 10-32 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 1 × 1 in with square corners (the real bar's corners are rounded, so the pocket clears them); extrude the DXF or subtract the 1000 mm STEP, then open the pocket by your fit.
How heavy is 1010 extrusion?
0.0424 lb/in (0.5088 lb/ft), 0.437 in² section, as 80/20 states.
What in this model is not taken straight from the drawing?
The drawing does not dimension the outer corner radii, so the corners are square: a pocket cut from this file clears the real rounded corners. Face grooves are left off.
