Change the name of your project in the upper left of the workplane.

If your units are not in millimeters, select Settings (in the bottom right of your workplace) and then use the dropdown Units box to select millimeters.

Place First Shape

Select the box shape and place onto workplane.

Adjust Box Size

Screenshot 2024-08-27 161733.png

Adjust the shape width to 50 mm, shape length to 20 mm, and the shape height to 2 mm using the Box form fields.

Create Reading Window

Select the Box Hole shape (the first shape option) and drag onto workplane over your box.

We want a 3 mm frame so we will subtract 6 mm (3 mm for each side) from our box dimensions, leaving us with 14 mm length and 44 mm width for our hole. This window size is customizable based on your reading material. If you have smaller font or only want to see one line at a time, you may want to reduce the size of your reading window. Use your measuring tape or caliper to measure your reading material.

Adjust the height to 4 mm so we can make sure it goes all the way through our material.

Using a caliper, measure the diameter of the finger you want your ring to fit between the first and second joint.

Return to basic shapes and add cylinder to workplane near the Ring Base.

Click the bottom, right node (a white square), and adjust the measurements of each side to your finger size plus 4 mm. For example, if your finger measured 14 mm your cylinder sides will be 18 mm.

Select the top, white node and adjust the height to 2 mm.

Drag the cylinder onto the Ring Base until the bottom of the cynlinder meets the hole. Do not allow the cylinder to overlap the hole.

Add a cylinder hole to the workplane over the cylinder. Adjust the measurement of each side to equal your finger size. Pull the hole down until it is at least 1 mm below the workplane.

Align the hole to the cylinder using both center dots. Group.

Select the Ring and the Ring Base. Align using bottom, center dot.
