I sadly found that the desings are no longer available from opendesk.cc and this option have been removed since a while and for a not clear reason since they claim it to be due to “maintenance” but according to web found reports they removed it too much time ago to really make sense that have done it due to maintenance.
The point is that the files are still allowed to use for non comercial purposes (what fit with the use I would make, but are no longer available).
There are still a couple of sources where some of the designs can be found
https://3dwarehouse.sketchup.com/by/opendesk with the designs in sketchup format that I don’t know how to split in parts with fusion 360
https://github.com/abetusk/dev/tree/release/projects/maslowcnc/opendesk with some missing designs
Could possibly someone have the studio desk design and others?
