Order rocket supplies

Everything you need to build and fly a rocket from Rocket Builder, apart from the rocket itself: a launch pad, motors, igniters, parachutes, filament, glue and paint. Items marked Start here are what I'd buy first.

First launch starter kit

New to model rockets? These five are everything you need, besides your printed rocket, for a first launch day.

Then browse the full list below for spares, bigger parachutes, filament, glue and paint.

Launch pad

A pad, a rod and a controller. The combo is the easiest way to start.

Launch controllers

The controller fires the igniter from a safe distance over its cable. All of these use a safety key or arming step before launch.

Igniters

Each launch uses one igniter. Buy extras: they're cheap and a dud ends the day.

Motors

Motors come in sizes: 13 mm minis, 18 mm (the most common), 24 mm and 29 mm. Buy the size your rocket was built for. After a build, Rocket Builder recommends a motor and links it here; the number after the dash is the delay, so match that too. Motors are bought and handled by a grown-up.

Recovery wadding

Flame-resistant wadding goes between the motor and the parachute so the ejection charge doesn't burn it.

Parachutes

Bigger parachutes land softer but drift further. Printed rockets are heavier than cardboard ones, so size up.

Shock cords

The shock cord ties the nose cone, parachute and body together so nothing comes down on its own.

Filament

What I print my rockets with. All Sunlu, 1.75 mm, 1 kg spools; other colors are on each listing.

Glue

Super glue (CA) bonds PLA, ABS and ASA well. PETG is slicker, so scuff both faces with sandpaper before gluing it. ABS and ASA parts can also be welded with acetone; PLA and PETG can't.

Primer and spray paint

Filler primer hides layer lines; sand it smooth, then paint. Bright colors are much easier to find in a field.

Masking tape and design stencils

Fine masking tape gives the crisp stripes and checkered roll patterns real rockets wear; stencils add stars and shapes.

Letter and number stencils

Name your rocket or number it for launch day. Pick the size by the body tube: 1/2" fits an 18 mm rocket, 1–2" suits bigger ones.
