tl;dr: If you are looking to 3d-print face-shield frames for emergency services, but have a print-bed thats too small, here is an STL that should allow for the same result (with a modular frame)
Download: RSA_FACE_SHIELD_MULTI
For convenience, you can 3d-print these clips which seem to work for it too

Last week we saw a tweet from Lize Hartley that they were printing protective shields and handing them out to emergency services.
We 3D-printed these frames for shields for our staff who need to work during lockdown (we were identified as essential services) and will be printing for healthcare workers next. See post attached if you are able to help. pic.twitter.com/cWCIlxWVfT— Lize Hartley (@lizetheunicorn) March 28, 2020
