ESD strap hanger for Botron B9742 grounding block

This mounts between the grounding block and the desk to allow you to hang an ESD strap. My biggest gripe with these B9742s is that there's no built-in provision for this, like you would find in a bent steel grounding block such as the Desco S1045. If you haven't bought an ESD grounding block yet, I would recommend getting one of those instead, but if you already have a B9742, I recommend printing one of these and adding it to your setup.

If it ever breaks, I'll add a V2 file with some additional reinforcement features, but I haven't had any issues with this one yet.
