Athlon Helos BTR gen2 6-24x56 zoom lever

I used an M3x15mm screw and hex nut, but the hole that the screw goes into is sized for M3 threads. an M3x10mm screw without a nut is probably fine. The hex hole for the 3mm nut is tight, but a bit of heat from a soldering iron and it slip right in, and won't fall out. The second file doesn't have the hex hole for the M3 but, but is other wise identical.
