Name Tag Holder - (Onshape)

This is a name tag holder I designed for a classroom. It can be remodeled or resized for other purposes, such as a paper/document basket.

Create a sketch on the top plane. Click on the drop-down next to the rectangle shape in the toolbar, and select the center point rectangle. Create a center point rectangle around the origin. It should be the dimensions of your desired paper, plus half an inch (e.g. If your name tag is 10 in by 3 in, make the rectangle 10.5 in by 3.5 in). Then, extrude to desired thickness, plus half an inch.

Next, use the shell tool on the top face of the new part, and set wall thickness to 0.2 in.

Create a new sketch on the rim of the box/face of extrude 1. Select the corner point rectangle tool, and draw a rectangle 0.2 inches wide and the total thickness of the box minus 0.2 in (1.3 inches in example). This should be drawn from the center of the box.

Now, use the revolve tool on the previous sketch, and make the revolve axis the side of the rectangle that is aligned with the center of the box. Set the revolve setting to remove, and confirm.

Select the Fillet tool from the tool bar. Use it on all outward facing edges and set radius to 0.1 in. For the side opening, fillet both edges. DO NOT fillet the bottom edges of the box.

Depending on your 3D printer of choice, you may not have a large enough build plate to print the container as-is. If this is the case, skip the next step, we will come back to it later.

Right click on the box that says "Part 1" in the bottom left hand corner. Then, select export. Export the file as a .stl, and make sure it is y-axis up. Finally, upload the file to a 3D slicer, and send it to a printer to be built. Congratulations! You just made a name tag holder!

Start by right clicking on the right plane and choose section view. Hit enter. Then, create a sketch on the right plane and draw a large rectangle that covers the whole cross section of the box. Extrude the new sketch to 0.01 in, and select symmetric. Set the extrusion to remove. Confirm the extrusion. Right click anywhere on the build area, and cancel the section view. Now, the name tag holder should be in two parts.

Rename the two parts "front" and "back" by right clicking on the part name, selecting rename, and typing your desired title for the part. Now, click on the eye symbol next to the "back part", hiding it. Create a new sketch on the cross section of the front (Face of Extrude 2), and draw a series of lines slightly smaller than the cross section of the box. Extrude the new sketch to one inch, so that it sticks out from the "front part" (video was too big so it had to be shortened).

Use transform to move the front part forward 1 inch (make sure to select translate by xyz), keeping the back part hidden. Create a new sketch on the face of the previous extrusion, and use the offset tool to create a slightly larger copy of the edges of said extrusion (offset should be 0.01 in). Extrude the new offset to 1.1 inches and set extrude to new. Un-hide the back part and hide the front part. Now use the boolean tool and select subtract, making the new Part 3 (created by the last extrusion) your tool, and the "back" part your target. Now, refer back to step 7, exporting two stl files instead of one.
