This is a magnetic insect screen for Trotec Wall Air Conditioners. You glue the magnetic ring with adhesive e.g. silicone to the Trotec wall outlet and then you can clip the insect screen over the complete outlet.
What you need for the build:
The screen clamping ring also has holes for threaded inserts if the clamping forces are to high and you need to pull the clamping ring out of the mainbody.
Attached you can also find the STEP Assembly, if you want to modify, remix, or improve the design.
The author marked this model as their own original creation.
