Abstract

A tool for use with wrapping paper is manufactured by a process comprising the step of causing a 3D printer to make the tool using an instruction file which is accessible to the 3D printer. The instruction file includes instructions for a hardware processor which define actions to be taken at and by the 3D printer to manufacture the tool. The tool manufactured in accordance with the instruction file comprises a unitary, plastic stick having a length which extends along an axis of elongation, a broad surface, a bracing surface, and first and second opposing sides extending along the length, separated by a width which is substantially less than the length. The first aide has serrations defined in the plastic stick adjacent the bracing surface. The second side has a non-serrated edge defined in the plastic stick proximate to the bracing surface.

Claims

1. A tool for use with wrapping paper, manufactured by a process comprising the step of:

causing a 3D printer to make the tool using an instruction file which is accessible to the 3D printer, the instruction file including instructions for a hardware processor which define actions to be taken at and by the 3D printer to manufacture the tool,

wherein the tool manufactured in accordance with the instruction file comprises;

a unitary, plastic stick having a length which extends linearly along an axis of elongation, a broad surface, a bracing surface which is positionable so as to be positioned on top of and in contact with the wrapping paper for restraining the paper from movement under the tool, first and second sides along the length which meet the bracing surface at respective first and second side edges, and a lip depending downward from the bracing surface of the plastic stick, wherein the first side extends parallel to the axis of elongation and comprises serrations defined in the plastic stick adjacent the bracing surface,

wherein the second side extends parallel to the axis of elongation and opposite to the first side and comprises a non-serrated edge defined in the plastic stick proximate to the bracing surface,

wherein the first and second sides are separated by a width in a direction perpendicular to the axis of elongation which is substantially less than the length,

wherein the lip is oriented perpendicular to the axis of elongation and defines a wall below the plane of the bracing surface, which is perpendicular to the axis of elongation,

wherein the wall defines a seat for an edge of the wrapping paper on top of which the bracing surface is positionable, and

wherein the wall defined by the lip is configured to self-orient the tool to be perpendicular to the edge of the wrapping paper when the wrapping paper edge is fully seated against the wall as a result of positioning the tool on top of and in contact with the wrapping paper for restraining the paper from movement under the tool and enabling a perpendicular cut.

2. The tool manufactured by the process of claim 1, wherein the instruction file has a single purpose of providing instructions to the hardware processor used by the 3D printer to define the actions to be taken at and by the 3D printer in order to manufacture the tool.

3. The tool manufactured by the process of claim 1, wherein the actions to be taken at and by the 3D printer in order to manufacture the tool include sintering loose material, and wherein the causing step responds to the instruction file by causing the 3D printer to sinter loose material at some locations and not others into the three-dimensional shape of the tool.

4. The tool manufactured by the process of claim 1, wherein the actions to be taken at and by the 3D printer in order to manufacture the tool include fusing loose material, and wherein the causing step responds to the instruction file by causing the 3D printer to fuse loose material at some locations and not others into the three-dimensional shape of the tool.

5. The tool manufactured by the process of claim 1, wherein the hardware processor is a component of the 3D printer.

6. The tool manufactured by the process of claim 1, wherein the hardware processor is a component of a client machine.

7. The tool manufactured by the process of claim 1, further comprising the step of downloading the instruction file from a hardware server.

8. The tool manufactured by the process of claim 7, wherein the step of downloading the instruction file comprises downloading the instruction file from a website.

9. The tool manufactured by the process of claim 1, wherein the instruction file comprises one or more computer-aided design/computer-aided manufacture files.

10. The tool manufactured by the process of claim 1, wherein the broad surface of the tool manufactured in accordance with the instruction file further comprises an arch extending in the direction of elongation between the first and second sides, and wherein an area of contact of the bracing surface is less than the area of the broad surface.

11. The tool manufactured by the process of claim 10, wherein the plastic stick comprising the tool manufactured in accordance with the instruction file has a flexibility, wherein the arch has a first curvature in a rest condition and a second, greater curvature in a flexed condition, wherein the arch moves between the rest condition and the flexed condition in response to a manual force being applied to the broad surface.

12. The tool manufactured by the process of claim 1, wherein the lip depends downward from at least one end of the bracing surface of the plastic stick.

13. The tool manufactured by the process of claim 1, wherein the serrations of the first side of the tool manufactured in accordance with the instruction file extend to at least one end of the length of the plastic stick.

14. The tool manufactured by the process of claim 1, wherein the non-serrated edge of the second side of the tool manufactured in accordance with the instruction file is either tapered or rounded.

15. The tool manufactured by the process of claim 1, wherein the plastic stick comprising the tool manufactured in accordance with the instruction file is transparent.

16. The tool manufactured by the process of claim 1, wherein the plastic stick comprising the tool manufactured in accordance with the instruction file is translucent.
