Miếng Insert thay thế Sigma Overclamp Butler cho Bike Computer

I developed a replacement insert for the bike computer mount in the Sigma Overclamp Butler. The original inserts act as weak points and tend to break in crashes, which was frustrating since replacements weren’t available. My PETG-printed version holds up well — not quite as strong as the original, but reliable in normal use.
I've printed this version with supports.

Diameter: 34 mm, Height: 5 mm
Hole spacing: 20 mm, requires M2.5 countersunk screws.
