The Lasersaur CAD model is published here in 3DM (Rhino version 4), FCStd (FreeCAD v0.14+) and STEP (open standard). We use Rhino 5 for all modelling but FreeCAD works fine as a viewer during the assembly process. Since the UI of FreeCAD is still in its early development check out this Survival Guide to get through some initial roughness.
If you need the model in other formats, FreeCAD can import/export IGES, STEP, VRML, and STL. Especially IGES and STEP is reported to work well due to the proven OpenCascade kernel. It takes about 15min to download FreeCAD and export to any of these formats.

The following job files can be used to manufacture the MechParts. We also provide a .ems file that can be used directly with emachineshop.com. You open this with their free CAD app, quote, and order directly with it. Material is 6mm aluminum (6mm acrylic has been reported to work too). Units are millimeters (mm).

The Lasersaur has five acrylic panels: one entry panel and four panels for seperating the laser from the main compartment. Additionally there are four small pieces to cove the cable feed-through holes.
Material is 3mm acrylic. NOTE: Double-check for inadvertent scaling in your SVG program.

Lasersaur uses the Driveboard Element for control. The design files are located in their own Github project.
To build one of these you need to order the board by sending the gerber files to a PCB factory and hand-solder it. All the components are on the v17.03 BOM designated as "electronics/driveboard". The SMD component soldering takes a bit of experience but is quite easy due to the usage of fairly big packages. In case you have never done this you can probably pull it off by watching some "smd soldering tutorial" videos on youtube.
The case can be ordered from protocase.com or otherwise manufactured from sheet aluminum.

The nozzle of the nozzle assembly is a custom aluminum part. The part can be machined on a lathe based on the following dxf or ordered from emachineshop.com with the following .ems file. This file loads into their free CAD app and can be quoted and order with it.
The part is made from aluminum on a lathe and has a tapped M5 hole on the side. The nozzle tip is then friction-fit with the Thorlabs lens tube. We use a strong vise for the mating process.

These mounts work with laser tubes of 50mm diameter. Most Chinese 40W tubes can be mounted with these. Cut from 6mm acrylic or aluminium.
