Predrilled box channel?
Hello.
I recently saw a few robots using some form of predrilled 1" box channel, which I can only assume is very convenient. In looking online, however, all I was able to find was the versapro chassis tube and the holey profile from 8020. However, the versapro stuff seems too thin and the holey profile is too big I believe. Does anyone know where this magical material may be sourced from?
Thanks,
Hades
