A8 on Dualtron Spider mudguard

I was using "Antusi A8" on my bicycle and wanted to use it on my Dualtron Spider, so I designed this adapter for mounting it. One needs to drill two holes on mudguard, one for M3 screw for the alarm/lamp in rear and one for small self tapping screw in front. I've been using it for a few months, and this is third iteration (probably final).

I printed in PETG, used Cura slicer, 30% gyroid infil, 1.2mm walls. Printed with tip at the top.
