Paper Template

Don't have access to a 3D printer? No problem! Print out a paper template and use it to make your own PCB mount out of foam core, cardboard or a sheet of plastic, dealers choice!

PDF Vector Artwork

Download the PDF and print it out on paper. This was designed to fit on a 8.5in x 11in sheet of paper. The dimensions of the mount are noted for checking if the scaling is correct after the print.

Foam Core Board

For this project we cut the shape out of foam core board. I suggest adhering the paper template over the work piece first (glue stick). Insert the tip of the blade to make several incisions and follow the outline. Cutting curves can be tricky so take your time! A rotary tool with a drill bit can be used to create the mounting holes.

Take caution and be careful when using knifes and operating power tools! For best safety, young makers ought to have adult supervision.

PCB Mount Screws

Use the following hardware for mounting the HalloWing M4 to the mount. Insert the nylon screw through one of the mounting holes through the top. Hold in place and install standoff by fastening onto screw thread.

  • 4 x M2.5 x 8mm female to female standoffs
  • 4x M2.5 x 4mm screws

Test Fitting

Follow the tear down section before test fitting the cut piece into the base of the candy bowl. It should have a snug fit when press fitting it through the eye hole. 

Cut Pieces

I made several cut pieces before getting the right shape and fitting. Like stated above, cutting curves can be rather tricky!  A few attempts makes for good practice. For this small part, cutting pieces by hand beats dealing with 3D printers or laser cutters.

Lens Holder

The lens holder requires a bit more precision to fit the lens. If you don't have a 3D printer, you can purchase the acrylic lens holder from the shop. Longer screws may be needed to pass through acrylic, pcb and standoffs.
