This is an addition to my RC plane modular wall storage system. To make use of these files, you must as well download the basic files found under the above link.
These swivel type wing holders are quite the same as those in the original file set - with one essential difference: They increase the distance between the model and the wall by 36 mm, thus allowing to mount planes with a landing skid underneath the fuselage.
They use the same bases and screws as the original swivels.
As usual, find details in the attached PDF manual. It's just the same manual as that on the project's main page - I didn't bother to change it since printing and mounting the new swivels is just the same as with the original ones.
The author remixed this model.
