Russian Doll 3D Cylinder MazeBlind

We are looking for a ring that will eventually be printed in sterling, featuring bare branches. Ring band needs to resemble a branch (or branches), and the top of the ring needs branches wrapping about it. Inside this ring we'll be adding an element later, so we need a pocket underneath the branches that will fit an item that is approx 5mmx20mm. The design sketch shows a bit of a lip to the pocket from the side view, this will help keep the item in place. Once the design is approved, we'll need it in US sizes 5-13.

Design two symmetrical Rhombicuboctahedrons (Rohm' for short) for printing on Prusa 3D MK2. The 1st Rhom' needs to be made of 2 parts that can be connected to form the complete shape. The width of the Rhom' should be 100nn from face to face. Each edge of this Rhom' needs to have a 5mm high 'fence' sticking outward. Two inner benches or plates need to be constructed in the inner space of each of the halves. The 2nd Rhom' is also made of 2 parts but without fences and without benches. It is a simple Rhom'. It needs to fit exactly on the 1st Rhom' from the outside. so that the 1st Rohm' go inside the second one. The attached jpg and max files depict the 1st Rhom'. However the max file is full of mistakes and should not be used as anything but as a general reference. Nor the 'fences' need to be constructed as V shape as in the max files. Please ask me anything which is not clear.

This contest is to design a very simple wristband attachment accessory piece that can hold a piece of fabric that was cut in a circle. The overall shape of the piece is a football/oval shape. I am attaching some pictures to show a prototype that I made out of paper. There should be 2 triangle shaped holes on the 2 ends that I can attach the piece to. There should also be an inner circle where I can glue the circle cut of fabric. The inner circle should be indented about a millimeter inward from the flat surface to place the cut of fabric. The inner circle should also be 1/2 inches in diameter. There should also be an outline around that inner circle that is flat with the front surface and that outline circle should be a diameter that is about 6 millimeters wider than the inner circle. The overall piece should be about 1.25-1.5 inches long in width from end to end and about 5/8 inches in height from the tallest point in the middle of the piece. All of these measurement can be changed if needed to make the design better, but the inner piece that fits that fabric should be able to comfortably fit a piece of fabric that is 1/2 inches in diameter.

look for someone to setup a 3d file from png file we are Official MOD Approved Merchandise with over 3000 badge we are an DTG pprinter company but we going into 3d printing and need files for this side of the work please find a copy of one of the badge

I am looking for a round clear plastic case design to be 3D printed for a prototype. This is very generic. The case should be 4.5 inches in diameter, round tapered off around the edge, and approximately 1 inch thick at the center, tapering off to about .25 inches until edges connect. The front and back should be of equal dimensions and attached by plastic and opens and closes, and snaps closed. The back should be black plasting, and the front should be clear plastic. This case would be very similar to something like a round eyelash case holder, or something that might hold ear buds.
