How to Use the RISER 3D Builder

The RISER 3D builder runs entirely in your browser — no account, no install. You pick a shape, dial in your height and wedge angle, choose a hole pattern, and export an STL. This guide walks through each section with screenshots taken directly from the tool.

Step 1 — Choose a Base Shape

Base Selection The builder opens with three base shape options. The Upload Silhouette panel appears below when you choose Cutout Base.

The builder opens with three base options (numbered in the screenshot above):

• ① Cutout Base — a flat riser with a custom shape cut into the top surface. Upload an SVG to set the cutout outline (your logo, a graphic, anything you can trace as an SVG).
• ② Outer Shape 1 — a standard rectangular pad with chamfered corners. No cutout. Best for structural rigidity and the simplest print.
• ③ Cutout Pocket — similar to Outer Shape 1 but with a recessed center pocket. Saves material while keeping the bolt-hole area solid.

If you want to add a logo or custom graphic, pick Cutout Base and click Upload Silhouette to load your SVG. If you just need a functional riser, Outer Shape 1 is the safest starting point.

Step 2 — Preview Your Shape

Live Preview ① The Live Preview (highlighted in red) shows a top-down view of your riser and updates in real time as you move the sliders.

Once a base is selected, the ① Live Preview panel (boxed in red above) shows a top-down SVG view of your riser. Every change you make in Settings is reflected immediately — you don't need to click a refresh button.

The preview shows bolt holes as circles and the outer shape as a solid fill. If you uploaded a silhouette, it appears as a cutout region inside the pad outline. Use the preview to check that bolt holes clear your cutout before you export.

Step 3 — Set Height, Angle, and Hole Pattern

Dimensions The five numbered controls: ① Units, ② Front/Rear Height, ③ Angle, ④ Angle Anchor, ⑤ Hole Pattern. Each is highlighted in red in the screenshot.

① Units

Toggle between Millimeters and Inches at the top of the Settings panel. All sliders and the dimension readouts update when you switch units.

② Front and Rear Height

Set the height of the front edge and the rear edge of the riser independently. If both heights are equal, you get a flat riser. If they differ, you get a wedge — the angle is calculated automatically from the height difference. In the screenshot, Front is 12mm and Rear is 8mm.

Common flat heights: 3mm (1/8"), 6mm (1/4"), 10mm (3/8"). For surfskate wedge setups, set the front higher than the rear (e.g. 12mm / 8mm) to get a few degrees of effective angle, which noticeably increases turn response.

③ Angle

The Angle slider lets you set the wedge angle directly in degrees instead of dialing the two heights manually. Setting front and rear to different values or moving the Angle slider achieves the same result — the builder keeps them in sync (the screenshot shows 3.0°).

④ Angle Anchor

When you add a wedge angle, one edge stays fixed at its height while the other moves. Angle Anchor has two options — Front Fixed or Rear Fixed — to choose which side stays put as the angle changes. Pick Rear Fixed if you want the rear to stay low and the front to lift.

⑤ Hole Pattern

Choose the bolt pattern to match your trucks. The builder offers four options:

• 8-Hole — both the new-school and old-school hole sets drilled together, so the riser fits decks set up for either pattern
• New / Old School — the standard 4-bolt pattern matching modern and classic trucks
• Slots — elongated slot holes for adjustable bolt positioning
• Slots + Holes — a combination of round holes and slots for maximum mounting flexibility

If you have a standard modern deck and trucks, New / Old School covers it; choose 8-Hole if your deck is drilled for both patterns.

Step 4 — Check Dimensions and Use Case

Export Summary ① The Use Case dropdown loads a starting setup; ② the Dimensions table summarizes every parameter before you export.

① Use Case (boxed at the top) is a quick-start dropdown — pick how you'll ride (Street / Park, cruiser, longboard, surfskate, etc.) and the builder loads sensible starting dimensions. The tip line just below the dropdown suggests adjustments, such as increasing rear height or angle to reduce wheel bite. Presets don't lock anything — tweak the sliders afterward.

② Dimensions (the lower box) is the spec sheet for your part. Review it before exporting — it shows the base shape, width and length, front and rear heights, the calculated angle, the hole pattern, and whether a silhouette is loaded.

Step 5 — Export or Share

Actions ① EXPORT STL downloads your model, ② BOLT LENGTH CALCULATOR and ③ CHECK WHEEL BITE TOOL open the helper tools — all highlighted in red.

① EXPORT STL

Clicking EXPORT STL (the red button) generates the 3D model from your current settings and downloads it as an .stl file. The file is generated entirely in your browser — nothing is sent to a server. Open the downloaded file in your slicer (Bambu Studio, PrusaSlicer, Cura, OrcaSlicer) and slice it for your printer.

Print recommendations:

• Material: PETG for outdoor durability, PLA for indoor/testing prints. See the PETG vs PLA guide.
• Infill: 100% for load-bearing strength — risers take significant compression force
• Layer height: 0.2mm is fine; 0.15mm for cleaner surfaces
• Supports: not needed for a flat riser; wedge risers may need supports on the thin edge if the angle is steep

② BOLT LENGTH CALCULATOR

Opens the bolt length calculator with your current riser height carried over. After adding a riser (especially a thick one), your existing bolts may be too short. The calculator tells you the exact bolt length for your hardware combination.

③ CHECK WHEEL BITE TOOL

Opens the wheel bite clearance tool. Enter your wheel diameter, truck height, and deck concave to see whether your wheels will clear the deck at the riser height you've set. Run this before printing if you're not sure your configuration will be safe.

SAVE TEMPLATE / SHARE

SAVE TEMPLATE stores your current configuration in your browser's local storage — it'll be there the next time you open the builder on the same device. SHARE generates a URL with your settings encoded, so you can send the exact configuration to someone else or bookmark it.

RESET BUILDER

Clears all settings back to defaults. Use this to start a new design from scratch.

From STL to Finished Riser

Once you have the STL file, the workflow is the same as any 3D print:

1. Open the STL in your slicer
2. Orient it flat-side down (the widest face on the build plate)
3. Set infill to 100%, layer height 0.15–0.2mm, no supports needed for flat risers
4. Slice, transfer to printer, print
5. Test-fit on your board before riding — bolt holes should be snug but not require force
6. Check wheel clearance once installed (press the nose and tail firmly by hand)

Print time for a standard 6mm flat riser is around 20–35 minutes on a modern printer. A pair of risers runs about an hour total.
