Laser Engraver
SUPERSPEED-660
The maximum printable area for this laser engraver is 806 x 450 mm.
Method 1: Export to AutoCAD as DXF file (geometry only). This option allows you copy/paste, move objects, and select different settings more easily.
Method 2: Use the SUPERSPEED-660 template in Inventor. This option allows you to work entirely in Inventor.

Sizing Tabs for Joints
Use a 0.7mm difference in size between the male and female sides of the joint.
The male side should be 0.7mm larger, but still centred with the female tab.
Note: With the previous laser engraver, we used 0.5mm because the width of the laser was smaller.
Method 1: Inventor to AutoCAD
Method 2: Plot from Inventor
Cutting Circle Holes for Square Axles
3mm x 3mm square axles will spin freely in holes that are designed with a 4.1mm diameter.
4.0mm holes will work for a tighter fit, but may require you to file down the edges.
