MRMF Print Queue
Read full descriptionHide full description
MRMF Print Queue is a private app for sending 3D-print requests to a friend who runs the printer. Create a group online, enter the access code your friend shared with you then: • Submit a request, describe what you'd like printed and, if you have them, attach STL, OBJ, 3MF, STEP, or G-code files plus reference images. • Track status in real time, watch your job move through pending, preparing, printing, done, on hold, or rejected. • Message the printer owner, ask questions or get notes about your print, right on the request. • Get push notifications, know the moment your status changes or a reply lands. This is a small, invite-only tool for friend groups, not a commercial print service. You'll need an access code from the person running the printer to use it.
