HOW-TO

How to generate a aluminium extrusion STEP / STL file

  1. 1Choose the 2020, 3030 or 4040 profile.
  2. 2Set the number of slots (2040 = 2 columns) and the length.
  3. 3Check the spec cards and any warnings.
  4. 4Download STEP, STL or 3MF — or send it to Orinovate for a quote.

What is T-slot aluminum extrusion?

T-slot extrusions are 6063-T5 aluminum profiles with slots on every face. With T-nuts and corner brackets they build machine frames, 3D-printer frames, workbenches and guards quickly. 2020 means a 20 × 20 mm section; 2040 is 20 × 40 mm with two slots per wide face.

Profile dimensions

2020: slot 6.2, lip 1.8, bore Ø4.2. 3030: slot 8.2, lip 2.2, bore Ø6.8. 4040: slot 10.2, lip 4.3, bore Ø8.5 (mm, after MISUMI HFS5 / HFS6 / HFS8).

FAQ

Which nut fits 2020 extrusion?

2020 (6 mm slot) takes M5 T-nuts or spring-loaded drop-in nuts for the 20 series. 3030 (8 mm slot) usually takes M6 T-nuts; 4040 (MISUMI HFS8, 10 mm slot) takes M8. Always check slot width and series (e.g. HFS5 = 20 series, slot 6).

Can I tap the centre hole?

Yes — 2020's Ø4.2 mm bore takes an M5 tap for end fastening, 3030's Ø6.8 mm takes M8 and 4040's Ø8.5 mm takes M10.

Is this accurate enough for a die?

No. Slot opening, slot depth and centre bore follow MISUMI HFS dimensions, but internal corner hollows are simplified. Use it for assemblies, clearance checks and printed jigs; the spec card shows the real profile's mass.

Which software opens the aluminium extrusion STEP file?

STEP (AP214) opens in Fusion 360, SolidWorks, FreeCAD, Onshape and Rhino. STL / 3MF import directly into Bambu Studio, PrusaSlicer or Cura.

About STEP / STL / 3MF / DXF

  • STEP (.step / .stp, AP214) keeps exact dimensions and surfaces for editing in Fusion 360, SolidWorks or FreeCAD.
  • STL and 3MF are triangle meshes that import directly into Bambu Studio, PrusaSlicer or Cura.
  • DXF is the top-view 2D outline, ready for laser cutting, waterjet or CNC routing.
  • All models are in millimetres at true scale.
