Step 1: Steal a 3D printer or I guess, buy one.
If you don't have one, stop here and just order the $40 belt attachments off Amazon and wait a few days.

Here's how you can 3d print a Vive tracker attachment. You'll need a 1/4 x 1/2 hex bolt and a 3D printer.

Look for the 1/4" - 20 bolts.
They look like this. I bought these at Lowes.
If you print the attachment below, the screw will fit into it like this.
Screw the bolt into the tracker, and line it up so a flat edge is towards the spike with the LED.

Then gently slide the attachment onto it.
Unscrew it slightly, then push the bolt as far back into the attachment as possible.

If you do it right, the Tracker's LED spike will point upward when the attachment is on something.
