No metal hardware is required—everything can be printed. In the second print file, there are parts that substitute for screws; these require glue and fit quite tightly. If they’re too tight to insert, you can reduce the model’s scale to 95% before printing. (If metal hardware is available, printing these parts isn’t necessary.)

Metal hardware can also be used: ten 6×18 mm screws paired with nuts.

A stainless steel round rod, 5×290 mm (relatively tight) or 4×290 mm (used with glue), is inserted through the center. Using a longer rod may cause it to protrude as a sharp spike at the attack head. With this stainless steel rod reinforcement, it might indeed help deter violence.

The attack head can be replaced with a strobe light; the mounting holes consist of two 6 mm circular apertures spaced 32 mm apart along the central axis.

Be sure to distinguish between left- and right-handed shields, otherwise the text will appear reversed. One end features a handle for attaching the attack head, while the other end has a hole for threading a cord.
