Huion WH1409 Under-Desk Mount - Rev. B

Huion WH1409 Under-Desk Mount — Rev. B (Refined, Adhesive-First Design)

A refined under-desk mounting system for theHuion WH1409 drawing tablet, redesigned from the ground up as aRev. B update to my original (and unexpectedly very popular) model. Note: Installed photos show the deprecated Rev. A bracket; rendered CAD images reflect Rev. B geometry.

The original mount worked — but it was blocky, less FDM-friendly than it should’ve been, and left a lot of refinement on the table. Rev. B tightens tolerances, improves print strength, modernizes mounting options, and introduces amodular installation spacer system to make alignment dramatically easier, cleaner, and more forgiving.

This is the version I wish I had released the first time.

What Changed (Rev. B Highlights)

Tighter, More Polished Fit

***Tablet opening reduced to 17 mm** (Tablet measures ~16.3 mm at thickest point)

• Cleaner engagement with less visual gap
• Refined chamfers more closely match the tablet’s contours

---

Designedfor FDM Printing

• Brackets now printvertically on their side
• More consistent wall stacking and layer loading
• Uniform3.2 mm wall thickness → Ideal for4 walls (recommended)
• Stronger, cleaner, and far less blocky than Rev. A

The result is a stiffer, more refined bracket that prints cleaner and holds tighter.

---

Adhesive-First Mounting (Recommended)

Rev. B shifts the primary mounting method away from screws.

***Top pad geometry precisely fits a 3M Command Small strip** (Designed around standard Command Small picture-hanging strips.)

• No desk damage
• Easy removal
• Plenty of holding power for the tablet’s weight

Screws are now secondary, not required.

That said…

---

Screw Mounting (Still Supported)

For users who prefer mechanical fastening:

***Screw shaft clearance:** 4.6 mm ***Countersunk head clearance:** 8.5 mm ***Bit extension bore:** 11.5 mm

• Designed around aDeWalt quick-change bit driver

Much tighter tolerances than Rev. A for cleaner installs.

New: Modular Installation Spacer System (Rev. B Exclusive)

Rev. B includesmultiple versions of the installation spacer tool, allowing installers to choose the level of guidance and rigidity that best fits their experience level and available print volume.

All spacer tools:

• Clip onto thebottom lip of the bracket (where the tablet rests)
• Automatically setcorrect tablet spacing (~15-7/16" nominal width with ~1 mm total clearance)
• Enforce parallelism between left/right and front/rear brackets
• Greatly reduce under-desk layout error and fatigue

Spacer Tool Variants

***5 mm height**

• Best usedin pairs

• Minimal filament

• Ideal for experienced installers who want quick reference alignment ***15 mm height**

• Excellentin pairs

• Acceptable solo use for proficient installers

• Strong balance of guidance vs material usage ***30 mm height**

• Goodsolo install option if carefully centered and kept square

• Offers meaningful rigidity without excessive filament ***55 mm height (Bracket height, rounded down)** +Most beginner-friendly option

• Tallest, stiffest, and easiest to keep square

• Requires the most filament, but makes alignment nearly foolproof

Choose the spacer height that matches your comfort level. All versions exist to reduce guesswork — not to lock you into a single workflow.

Using the Spacer Tools Correctly (Important)

The spacer tools included in Rev. B are designedonly for horizontal spacing — that is, setting the exact left ↔ right distance between eachpair of brackets.

They donot set the front ↔ rear spacing (the distance between the two rows), because a tool long enough to do that isn’t practical for most printers.

So the workflow is:

1.Install the outer brackets first (FR and RR, or FL and RL if mounting left-side). 2. Use the spacer tool to set the correct spacing for: ***Front-left ↔ front-right** ***Rear-left ↔ rear-right** 3. Reuse the same tool for both pairs.

This ensures both horizontal pairs are perfect — the tool handles that for you. Front–rear accuracy comes from your layout method.

---

Recommended Installation Strategies

You can approach the install two ways depending on comfort level:

###Method 1 — Structured Layout (Most Precise)

1. Mark therear edge of where the tablet will sit.
2. Mark theleft/right bracket positions using the spacer tool as a gauge.
3. Mount the tworear brackets first, ensuring:

• They’re aligned to your rear reference mark
• They’re perfectly parallel

1. Clip the tool on and install thefront brackets in line with the rear pair.

This producescabinet-grade accuracy when done carefully.

---

###Method 2 — Outer Brackets First (Fastest + Easiest)

My personal recommendation.

1. Mount either theFR orFL bracket first — choose the one closest to the edge of the desk where you can easily align it with a physical reference (desk edge = your friend).
2. Install the matchingRR orRL bracket directly behind it, making it: ***Square** ***Dead parallel** to the front bracket (Check with a small square if you have one — your high school science teacher would be proud.)
3. Clip the spacer tool onto the rear bracket and install the opposite-side RR/FR bracket at perfect spacing.
4. Reuse the spacer to set the matching front bracket.

This method uses the desk edge as your “free” square reference and the spacer tool as your “exact width” reference. For most users, this is the sweet spot between speed and precision.

Important Fit Notes (Read Before Installing)

• The spacer tool grips the lower rib of the bracket with0.3 mm face-to-face tolerance → That’s0.6 mm total clearance across the two tongs. → If your printer over-extrudes, the tool may grab too tight —calibrate your extrusion.
• If you're installing withscrews, make sure the tool is not so tight that it binds and cannot slide off toward the front. If it wedges, back the bracket screws out slightly, remove the tool, then retighten.
• If you're using3M Command strips:

• Theydo allow limited repositioning
• But don’t overwork a fresh adhesive — you’ll weaken the bond
• Likewise, don’t repeatedly cycle the velcro latch; you’ll wear it out → If you need to correct a major misalignment,replace the strips rather than fight them.

Be diligent and patient during alignment — you only need to get it right once.

The Real Goal: Perfect Square + Perfect Width

All four brackets need:

***Consistent width** (spacer tool handles this) ***Consistent length** (your marks or desk edge handle this) ***Perfect parallelism** between rows

The combination of:

• Adhesive-first mounting
• Modular spacer heights
• Refined bracket geometry
• And a little user care

…results in an extremely clean, confidence-inspiring install that Rev. A never came close to offering.

---

Orientation & Identification Improvements

***Huion logo debossed on the side**

• Clearly identifies bracket orientation
• Makes it obvious which side is up/down

• Bottom tablet-support lip isslightly longer by design

• Provides a subtle tactile cue during install

Small touches, big quality-of-life gains.

Print Recommendations

***Material:** PLA, PLA+, PETG, ABS, ASA all work well ***Layer height:** 0.15–0.20 mm ***Walls:** 4 (recommended) ***Infill:** Not critical due to wall-dominant geometry ***Brim:** Recommended

• Brackets stand ~55 mm tall when printed vertically

Rev. B prints more reliably than Rev. A despite being stronger.

This update exists because the original model clearly resonated with people — and this time, I wanted to eliminate friction at every step.

---

Summary

Rev. B is a refinement pass driven by real-world experience and hindsight.

Expect:

• Tighter fit and cleaner appearance
• Stronger brackets with better layer orientation
• Adhesive-first mounting (no desk damage)
• Optional screw mounting with improved tolerances
• A modular alignment spacer system that scales from beginner to expert installs

If you printed or used the original, this is the version you actually wanted.

Rev. A files have been deprecated to avoid confusion — Rev. B replaces them entirely.
