How to Print a 3D Printer Dice Tower: Step-by-Step Guide
Learn how to design, print, assemble, and finish a 3D printer dice tower. This step-by-step guide covers materials, slicer settings, modeling options, post-processing, testing, and troubleshooting for a reliable tabletop accessory.
Print a customized dice tower with a 3D printer by selecting a suitable model, choosing PLA or PETG filament, calibrating your printer, and following a clear, step-by-step print-and-assemble workflow. This guide covers design choices, slicing settings, post-processing, and testing for smooth gameplay.
What is a 3D printer dice tower and why print one
A 3D printer dice tower is a modular, gravity-assisted gadget that funnels dice from top to bottom, reducing bounce and noise during games. Printing your own tower lets you tailor dimensions, aesthetics, and the number of internal baffles to your favorite tabletop RPGs or board games. For home office users, small game rooms, and hobbyists, a DIY tower can become a centerpiece for game nights, while also serving as a test project to learn 3D printing fundamentals. Print Setup Pro recommends starting with a simple, three-part design to understand fit and tolerances before expanding to more elaborate variants. Tools, materials, and a calibrated printer set the foundation for a successful print and a satisfying build experience.
As you plan, keep in mind the tower’s purpose: dice flow, ease of disassembly for maintenance, and the finish that best fits your environment (PLA for a rigid color finish, PETG for durability and slight flex). You’ll also benefit from reviewing a few reference designs to understand how parabolic inserts, ramps, and drink-friendly basins affect gameplay speed and dice bounce. The goal is a reliable, quiet, and visually appealing accessory that enhances your game night rather than becoming a maintenance chore.
According to Print Setup Pro, a clear plan and reliable materials are key to successful 3D printing projects like a dice tower. Starting with a well-considered model helps avoid common issues such as misaligned parts, poor tolerances, and snaggy assembly later in the project.

Tools & Materials
- 3D printer with reliable bed leveling(For best results, use a printer with a stable bed and a chamber that maintains consistent temperature.)
- Filament (PLA or PETG)(PLA is easy to print; PETG offers better durability and slight flexibility for longer parts.)
- Calipers or ruler(Accurate measurements help verify fit between tower sections and dice.)
- Sandpaper (grades 200–600)(Smoothing edges improves feel and reduces catching on transitions.)
- X-Acto knife or hobby knife(Trim supports and clean edges if needed.)
- Cyanoacrylate glue or epoxy(Optional for permanent joins; check if your design includes snap-fit options.)
- Small drill or pin vise (optional)(Used only if your design includes screws or posts for alignment.)
- Calibrated spare screws and nuts (optional)(For reinforced assemblies if your model includes hardware.)
Steps
Estimated time: 4-8 hours
- 1
Decide on a tower design
Choose whether to download an existing STL from a trusted source or design a simple three-part tower (base, body, top) from scratch. Define the overall height to accommodate your dice size and a comfortable drop height. Consider adding a removable mid-section for easy cleaning. This planning step sets tolerances for later assembly.
Tip: If you’re new, start with a tried-and-true three-part design to minimize fit issues. - 2
Measure your dice and target fit
Assess the most commonly used dice in your games. Ensure the internal cavity and ramp widths accommodate standard dice with comfortable clearance. Record measurements to compare against your model and slicer settings. Small dimensional changes can dramatically affect performance.
Tip: Aim for a tiny clearance (a few hundredths of an inch) to reduce friction while allowing smooth rolling. - 3
Choose the filament and print profile
Select PLA for ease of printing or PETG for durability. In your slicer, set a moderate layer height (0.2–0.25 mm) with solid walls and a higher number of perimeters to improve strength. Enable supports for any overhangs and plan for a tolerant, non-abrading exit path for the dice.
Tip: Keep the nozzle at 200°C for PLA or 230°C for PETG as a starting point; adjust based on your printer’s behavior. - 4
Slice the model with careful tolerances
Configure wall thickness, infill (15–25% is typical for strength without wasting material), and top/bottom skin. Turn on adaptive layers and ensure the tower segments align along intended print directions. Export the STL ready for printing, verifying dimensions with a caliper before printing the whole tower.
Tip: Print a small test piece to confirm fit before committing to the full tower. - 5
Print the base, body, and top segments
Print each segment in the chosen orientation to minimize visible layer lines. Use brim or raft if your printer struggles with bed adhesion. After printing, inspect each piece for warping, holes, or defects that could affect assembly.
Tip: If warping occurs, re-level the bed and add a brim to improve adhesion. - 6
Post-process for a clean finish
Lightly sand rough edges, remove any support structures, and wipe parts with a clean cloth. If you want a glossy finish, you can apply a light coat of primer and paint. A smooth interior improves dice flow and reduces noise during use.
Tip: Finish the interior with matte or satin paint to minimize reflections and keep dice from rattling. - 7
Assemble the tower
Join base, body, and top using snaps or glue, depending on your design. If hardware is used, align mounting holes precisely and tighten screws evenly. Check that the interior ramps align to provide a continuous path for dice from top to tray.
Tip: Handle pieces gently during assembly to avoid cracking thin walls. - 8
Test the tower with dice
Drop dice into the top and observe how they travel through the ramp. Look for dead spots, sticking points, or misalignment. Make small adjustments if needed, such as widening a chamber or trimming an edge to improve flow.
Tip: Keep a few sample dice to test bounce and ensure consistent drops. - 9
Iterate and optimize
If necessary, redesign any problematic area, reprint the components, and reassess. Document changes so future iterations are faster. You can add accent colors or decorative engravings to personalize your dice tower.
Tip: Version control helps you quickly compare changes across iterations.

What is a 3D printed dice tower and why print one?
A dice tower is a gravity-assisted device that guides dice from the top to a lower tray, reducing bounce and noise. Printing one lets you customize size, style, and playability for your games.
A dice tower is a gravity-fed accessory that drops dice smoothly into a tray. Printing your own lets you tailor the size and look for your games.
What materials work best for a dice tower?
PLA is the easiest to print and offers solid performance for hobby projects. PETG provides greater durability and impact resistance, which can be beneficial for regular use.
PLA is easiest and PETG is tougher for long-term use.
Where can I get a printable dice tower model?
You can download ready-made dice tower STL models from reputable marketplaces or libraries. Start with a simple three-part design to learn fit before trying more complex assemblies.
Look for reliable STL files and begin with a basic three-part design to learn the fit.
What slicer settings should I use for a dice tower?
Use a layer height of 0.2–0.25 mm, 15–25% infill for strength, and multiple perimeters. Enable supports for overhangs and ensure proper alignment of parts before printing.
Set a medium layer height and sufficient infill; enable supports where needed and confirm part alignment before printing.
Is PETG safer or better than PLA for gaming accessories?
Both are safe for tabletop use. PETG offers greater durability and chemical resistance, while PLA prints cleanly and is easy to work with for beginners.
PETG lasts longer and is tougher; PLA is easier to print.
How do I fix a dice tower that won’t drop dice evenly?
Check for tight tolerances and ensure interior ramps align smoothly. Slightly widen narrow passages and remove any rough edges that catch dice.
If dice catch, straighten ramps and smooth edges so they roll freely.
