Description

Signal Dock is a monitor riser built from two end pedestals and a shelf that bridges them. Each pedestal hides a drawer behind its front face, so pens, cables, and a spare SSD stay off the desk without a separate organizer. A clip-on cradle on the right pedestal holds a phone or small tablet at a fixed angle, positioned for a second screen, a video-call camera, or a smart-display dock running a voice assistant.

The shelf spans the gap between the pedestals and carries the monitor's full footprint, with a cable channel routed into its underside so the monitor's power and video cables tuck out of sight instead of draping over the front edge.

Why it sells

Monitor risers with built-in drawers are an established Etsy category: one listing selling a two-drawer PLA riser has gathered 86 reviews (Etsy, 3D Printed Monitor Riser With Drawers), and an adaptable monitor shelf from a different seller has 207 favorites (Etsy, Monitor Shelf). Broader seller round-ups list "desk organizers, drawer dividers, and cable clips" and headphone stands as consistent categories that "attract gamers, streamers, music lovers, and office workers alike" (Creality, Top 22 Best-Selling 3D Printed Items).

None of the listings turned up in this research combine the drawer storage with a second-device dock — every riser sells storage, every phone stand sells propping up a phone, but none pair the two into one desk fixture. Signal Dock's cradle fills that gap for the growing number of people running a phone-based AI assistant or a second video feed alongside their main monitor.

Who buys it

Remote workers and streamers who want their desk screen raised to eye level and want a second device (phone, tablet, smart display) propped at a working angle next to it — the same buyer who already shops Etsy's monitor-riser and phone-stand categories, typically as a desk upgrade rather than a gift.

Design overview

• Two identical end pedestals, each hiding a front-loading drawer
• A shelf bridges the pedestals and carries the monitor's feet
• A cable channel is molded into the shelf's underside, routed to the back edge
• A clip-on tilt dock seats a phone or small tablet at 65° from vertical on the right pedestal
• Felt pad on the dock cradle keeps the device from scuffing or sliding
• Finger-pull notches on both drawer fronts — no separate pull hardware
• The one feature the Etsy listings researched don't have: a built-in second-device dock, so the riser replaces both a drawer organizer and a phone stand

Dimensions

Parts list

Hardware and non-printed parts

• Self-adhesive felt pads, 20 mm round ×4 — one under each pedestal foot corner, protects desk surface
• Self-adhesive felt strip, 100 × 12 mm ×1 — lines the AI dock cradle slot so a phone doesn't scuff
• 6 × 3 mm N35 disc magnet ×0 — not used; dock clip is a dovetail slide, no magnets needed

Fits and tolerances

• Drawer inside pedestal bay: sliding fit, 0.3 mm clearance per side (standard sliding fits in this design use 0.2 mm, but the drawer's 178 mm travel is long enough that a tighter gap risks binding if either part warps slightly, so the extra 0.1 mm buys margin)
• Shelf lip into pedestal top rebate: sliding fit, 0.2 mm clearance per side
• AI dock clip dovetail onto pedestal side rail: sliding fit, 0.2 mm clearance per side

Modeling guide

Origin sits at the bottom-left-front corner of the left pedestal; +X runs right toward the second pedestal, +Y runs back away from the user, +Z runs up.

End pedestal (model once, print twice):

1. Sketch on XY at Z=0: rectangle 170 × 200, corner radius 6 mm.
2. Extrude 85 mm up.
3. Shell the extrusion inward 3 mm, leaving the top face open.
4. On the front face (Y=0 side), sketch a rectangle 140 × 45 centered at X=85, Z=55 (bay opening).
5. Cut that rectangle through to Y=180 to form the drawer bay (180 mm deep).
6. On the front face of the bay cut, add a half-circle notch, radius 15 mm, depth 5 mm, centered at X=85, Z=32.5, for the finger pull — this step is cosmetic only and skippable on a first build.
7. On the top face, cut a rebate 216 mm long × 198 mm deep × 3 mm tall along the inner edge (for the shelf lip to seat into) on the pedestal that will carry the shelf end.
8. On the right pedestal's outer side face (X=170 plane), add a dovetail rail: a trapezoidal rib 60 mm long × 8 mm wide at the base tapering to 6 mm, protruding 4 mm, centered at Y=100, Z=70.

Drawer:

1. Sketch on XY: rectangle 139.4 × 43.4, corner radius 4 mm.
2. Extrude 179.4 mm (travel direction).
3. Shell inward 2 mm, leaving the front face (short end) open.

Shelf (bridge panel):

1. Sketch on XY: rectangle 216 × 198, corner radius 4 mm.
2. Extrude 10 mm.
3. On each short end (X=0 and X=216), add a lip tab 198 × 15 × 3 mm protruding down, matching the pedestal top rebate.
4. On the underside, cut a cable channel 20 mm wide × 12 mm deep, running the full 216 mm length along Y=20 from the back edge.
5. On the top face, add 2 mm-tall, 1 mm-wide parallel ribs spaced 10 mm apart, running the full width, for a light non-slip texture under the monitor base.

AI dock clip:

1. Sketch on XY: rectangle 70 × 60, corner radius 5 mm.
2. Extrude 20 mm as the mounting base.
3. On the base's inner face, cut a dovetail groove matching the pedestal's rail (trapezoidal, 60 × 8/6 × 4 mm) so the clip slides on from the top.
4. From the top of the base, extrude a cradle arm angled 65° from vertical, 120 mm long, cross-section 40 × 15 mm, tapering to 40 × 10 mm at the tip.
5. Cut a slot into the cradle arm's face: 12 mm wide × 100 mm long × 10 mm deep, centered, to seat a phone or small tablet edge.
6. Add a 3 mm fillet to all cradle edges that contact the device.

Print settings

Assembly

1. Press felt pads onto the four bottom corners of each pedestal.
2. Slide each drawer into its pedestal's bay.
3. Seat the shelf's end lips into both pedestals' top rebates.
4. Slide the AI dock clip onto the right pedestal's side rail from the top until it stops.
5. Press the felt strip into the dock clip's cradle slot.
6. Set the monitor (or monitor stand) on the shelf.

Variants and upsells

• Widen the shelf and pedestal spacing for 32"+ monitors (parametric: pedestal_gap_mm)
• Swap the dock clip's 65° angle for a steeper or shallower version for different device sizes
• Offer a left-and-right drawer-only variant without the dock, for buyers who just want storage
• Bundle with a second dock clip so both pedestals can hold a device

Selling and distribution

List on Etsy and Printables, the two channels where the comparable monitor-riser-with-drawers listings above are already active. Price the printed unit using roughly 490 g of PLA (~$12 in filament at typical spool pricing) plus 14 hours of machine time, which puts $42–$58 in line with the researched listings' price tier once margin and packaging are added. Sell both the printed object and the STL bundle; license the file non-commercially (CC BY-NC) so buyers can print one for personal use but can't resell the files. Listing keywords: monitor riser, desk organizer, phone stand, tablet dock, cable management, drawer organizer, desk accessory, AI assistant stand, webcam riser, office gift.

Risks and IP notes

• The shelf's 216 mm single-piece width leaves only 4 mm of margin inside the 220 mm build volume; print a test coupon first and trim the design down if your printer's effective bed is smaller than nominal.
• Monitor risers with drawers are a crowded Etsy niche already; the dock clip is the differentiator, so keep it prominent in listing photos rather than treating it as an accessory.
• The dovetail rail is a visible design element on competitors' similar organizer products; this slide-on rail geometry is generic and not tied to any specific patented mechanism, but a quick design-patent search before a commercial launch is good practice.
• The dock clip's cradle arm is a thin cantilevered print; if it cracks under phone weight, thicken the arm cross-section before offering it as a standalone add-on.
