CAD Files (Bookshelf F.F.)

Laser-Cut Elements

The enclosure was created in Boxes.py (online tool for designing laser-cut boxes). That tool creates an SVG, which was then downloaded and customized in Inkscape.

The final SVG File for Laser-Cutting the Enclosure of Model 3 (Bookshelf F.F.) is hosted at the dolphindaq repository.

You can download that SVG, then import it into your laser-cutter's software. It's designed to be cut on 1/8" basswoood (having tweaked the interlocking gaps on Boxes.py for a nice press-fit). Before you do the cuts, make note of instructions within the SVG about which layers must be scored, and which layers must be cut through.

3D-Printed Elements

There are a few beam enclosures that the lasers and photodiode fit into, that are 3D printed. CAD files from which the Model 3 (Bookshelf Form Factor) were built are on Fusion360. I've exported them to STL files. Reach out to me if you get confused on how these pieces fit together.

The STL files are all together in the dolphindaq repository.

You will need to print out:

  • Three "Extra Collimated Laser Holder" (print in white). The extra-collimated version is nice for safety purposes, as it blocks unwanted angles of emission.

  • Three "Detector Base" (print one in white, two in black). These hold the photodetectors.

  • Three "Regular Pinhole Detector Barrel" (print one in white, two in black). These press into the Detector Bases, holding in the photodetectors / diffusing pucks and collimating the incoming light.

  • (Optional) Three "Diffusing Puck" (print in white). These sit directly on top of the photodetectors.
