This is the verison for 16" duct - only the front piece. If you agree with the solution we will do final touches and then I can provide the other dimensions.
I hope I understood correctly: your description differs from the image you uploaded. I followed the description an I designed a two piece assembly: the flange (fixed part) and the cover (lid). I hope that this is what you're looking for.
Feedback will be greatly appreciated.

#6 air_filter_cover_v2 by DaBu
This is a new design based on your last remarks. I aimed for a "stright-pull" with no undercuts design wich simplifies the mold and reduces costs. Unfortunatly, given the fact that molded parts shoud have drafted walls (for extraction from mold) the two seals can't be the same size.
I am looking forward for your comments.

Everyone will be stating their designs are injection capable. And almost all are, but at what cost. How complex will the mold need to be? How many additional slides will be needed? Keeping the design as simple as possible is the key to success in manufacturing.

My designs have been created with injection molding in mind. All draft for injection molding has already been added. Considerations for mold parting lines and mold slides have also been made.

Can the design of the hinges and tabs be a bit soft? so that they can't be so obvious to the eye? And also does the design have to be exactly as the sketches or can we add a personal touch with does dimensions??

Vehicular LED Display Case
I am prototyping a display for a startup that will be mounted on the tops of vehicles. It will eventually be either CNC milled or 3D printed, depending on the material decided on. For this display I am looking for a sleek case design that also meets the specifications below. The display panel itself is 81.75625 cm x 15.24 cm and needs to be able to slide into and out of the case when a side panel is removed. The electronics are mounted on the back of the display panel and require a clearance of 5.08 cm. There needs to be a source of ventilation for the electronics except on the top as it will be outdoors, as well as one usb port and space for the power cable on the bottom of the display case. For the feet, they will be made of magnets with quite a strong pull force that have been dipped in rubber to prevent scratching. This also needs to be accounted for in the design with there being 3 to 4 feet supporting the case. There are other cases for various products that need to be designed/redesigned, so we would like to find somebody to work with through this contest.
