I have been thinking about 3D printing for this reason.
I am debating if to get the ply floor with the circular cut outs for the load strapping point, but thought it may look 'unfinished'.
My idea was to 3D print a blanking plug that either looked ok, or could be covered with the same material as the rest of the floor but easily removable if a load needed to be secured.
(A bit like the plastic things to go on a desk where the computer cables etc go through.)
Have you seen this? Been Busy Lately....Most things we’ve printed are Star Wars parts lol
what file types can your printer take? step?
