HexFloat – Invisible RC Car Shelf – 1:10 (240 × 100 mm)

📦 Description

A wall bracket that holds a 1:10 RC car — and then gets out of the way.

The shelf slides in under the chassis, between the wheels, so from the front you see the car floating on the wall and almost nothing of the mount itself. One bracket carries one car; the deck is short enough to stay hidden behind the body, and wide enough that the chassis sits flat and stable on it.

Designed around a Traxxas Slash 4×4, but the deck is a plain flat platform with no car‑specific features, so it fits most 1:10 short course trucks, buggies and crawlers — Traxxas, Arrma, and similar.

🔹 What it holds

• Scale: 1:10

• Tested with models in the 3–5 kg range

• One bracket per car — no pairs, no rails, no spacing to work out

• Wheels hang free on both sides, nothing touches the bodyshell

🔹 Design features

The deck uses an open honeycomb structure, which gives:

• high stiffness where the load is, with very little material

• a clean, technical look that reads as part of the car, not as furniture

• shorter print time thanks to the lightweight geometry

• dirt and gravel from the tyres fall straight through instead of collecting on the shelf

The back plate is deliberately thick — it is the part that takes the leverage of a fully loaded deck cantilevered off the wall. Chamfered edges all round, countersunk screw holes, no visible hardware from the front.

🔹 Dimensions

• Overall: 240 × 100 × 70 mm

• Projection from the wall: 220 mm

• Deck: 220 × 95 × 15 mm

• Back plate: 100 × 70 × 20 mm

• Two countersunk holes for M4 / 4 mm wall screws

🔹 Mounting

Use two screws into a plug or anchor rated for the load — the bracket is stronger than most plasterboard fixings, so the wall is the limiting factor, not the print. In a stud or solid masonry wall, ordinary 4 mm screws are enough.

Mount the bracket so the deck ends up under the chassis rails, roughly at the car's centre of gravity. Cars stacked vertically look best with 250–300 mm of spacing.

🔹 Print settings

• Layer height: 0.2 mm

• Nozzle: 0.4 mm

• Perimeters: 4 (this part is loaded in bending — do not go below 3)

• Infill: 20 % (gyroid or grid)

• Material: PLA / PETG / ASA / PC

• Supports: none — the part prints deck‑down with the back plate standing up, so there is not a single overhang

• Brim: not needed

Print time approx. 7 h 20 min, about 140 g of filament.

PLA is perfectly adequate indoors. For a garage or anywhere that gets warm, use PETG or ASA.

🔹 HexFloat System

HexFloat is intended to grow into a small family of hidden wall mounts sharing the same honeycomb design language and back‑plate interface.

Planned variants:

• 1:8 — wider deck, deeper back plate

• 1:16 / 1:18 — scaled down, single‑screw version

• Accessory shelf — same look, for transmitters, batteries and tools
