Mini Picture Frame

I decided to make this because it could be useful for displaying small photos and/or polaroids.

I used onshape to make this part.

First, make a sketch on the front plane. Draw two center point rectangles, one inside the other. The outer rectangle has the dimensions 4 x 2.5 inches. The inner rectangle has the dimensions 3.5 x 2 inches.

Next, extrude the outer rectangle with a depth of 0.5 inches (forward).

After that, make the back of the frame by drawing a 4 x 2.5 inch rectangle that lines up with the edges of the existing frame.

To finalize the back of the frame, extrude it backwards 0.1 inches.

To make the groove where you can place the photo, draw a center point rectangle on the top plane, that is 2.2 inches long (1.1 inches on both sides of the origin). It has a width of 0.1 inches and is 0.05 inches away from the back of the frame.

To finalize the groove, extrude remove it symmetrically 3.7 inches.

The final step is to add a 0.25 inch fillet to the front edges of the frame, making it more decorative.
