Here's a cut-away of the main part. Two of them were snugged up to the handlebar (above cables) and held in place by tie-wraps going through a channel in the print. The slot with circular cutout is for end of knotted paracord that then goes above handlebar, below stem, back above handlebar, and into slot on other adaptor. This helps keep adaptors from rotating, without being overly rigid. The upper right area is what slides into the packβs support bar slot. There's a long hole down the middle of this part for a 3mm screw to provide additional rigidity. The little slot at bottom is where extra brace attaches, a little horizontal bar that helps transfer rotational loads to the rotating headset. More importantly it keeps the other two parts secured together. Originally tried to glue these, but that wasnβt solid enough and I drilled/screwed them together.
