3D Printed Watch Case Build

Introduction

This build is an easy project that adds a little style to your watch collection. This is a simple 2-watch design using simple components and 3D printed parts.

What You Will Need

List of materials is available below or via this link:

• Plymor Brand Clear Acrylic Square Polished Edge Display Base

• 2 Cylindrical 8mm Brass Barrel Invisible Furniture Hinge

• Leather Pillow for Watch Winder/Jewelry Organizer/Watch Display

• Sandable Primer Spray Paint, Black

• Multi Purpose Spray Paint, Matte Clear

• Ultra Cover 2X Spray Paint, Oil Rubbed Bronze

Any and all PPE equipment.

3D Printed Parts

Print time is roughly 17 hours for all 3 pieces @ 60 mm/s. The difficulty I would classify as easy for both the printing and assembly. 

Watch Case (decent surface quality to limit amount of sanding needed)

• Filament choice not really important

• 0.2mm layer height

• 25-30% infill (ideally you use multiple processes and use a high infill for at least the first 10mm if you can. 

• Support is optional depending on overhang performance

• Brim optional

Cover and Cover Back Plate

• Filament choice not really important

• 0.2mm or higher layer height

• 15-20% infill

• Support recommended

• Brim optional

Finishing 3D Prints

• Remove any support material.

• Sand pieces to the desired smoothness. Start with 220 or320 grit and move up until you have a nice smooth part without visible print lines. 

• Wipe the sanded parts with a lightly damp cloth or paper towel.

• Apply even and a light coat of primer.

• Allow enough time for the primer to dry, then sand lightly.

• Wipe the sanded parts with a lightly damp cloth or paper towel.

• Once the parts are dry, evenly apply light coat(s) of base coat spray paint.

• At this point, you can either finish with a clear coat or you can hydro-drip your parts (you can see a full guide on how to do that here.)

Assembly

Now you are ready to wrap your watches around the watch pillows, insert into the case and close the lid. I hope you enjoy your 3D printed watch case!

• Prepare acrylic by cutting to a 3.6” x 4.3” rectangle. I used painters tape, marked the lines, and then cut using a jigsaw.

• Slide acrylic rectangle into the back of the cover.

• Slide (glue optional) back cover plate behind the acrylic sheet. (For a seamless look, slide acrylic into before finishing the cover and use Bondo Spot Putty to fill the seam and then finish. 

• Review how hinges operate and ensure orientation is correct before inserting into all 4 mounting holes.

Thanks for taking the time to explore the project. I hope you try it, and if you do, I’d love to hear your feedback and see pictures of your build!
