Why wget? All that data is easily available over rsync:
$ rsync -az --stats rsync://rsync.alephobjects.com/lulzbot lulzbot
$ rsync -az --stats rsync://rsync.alephobjects.com/devel devel
$ rsync -az --stats rsync://rsync.alephobjects.com/ao ao
The directory sizes (excluding file system overhead) are 101 GiB for lulzbot, 219 GiB for devel, and 8.5 GiB for ao.
Also be sure to grab Git repositories from Phabricator (48 GiB in 212 repositories):
$ for r in $(wget -q -O - http://www.pehjota.net/~pj/code.alephobjects.com_repositories | grep '.git$'); do git clone --mirror "https://code.alephobjects.com/${r}" "${r}"; done
Agreed on expanding too quickly, but sadly I don’t see Prusa (or anyone else) as a replacement for LulzBot. They lack features like a modular carriage, real dual extrusion, and a double XZ frame for a really rigid and stable Y axis.
Yes, for anyone else, this will grab all that (13 GiB):
