Mini-RocketBox Plus+

Fill a Full Pre-Roll Batch Without Pre-Weighing Material

Pre-weighing material into individual cones before filling adds a whole extra step to every production run, and it's one of the slower parts of scaling up pre-roll output. The STM Mini-RocketBox Plus+ skips that step: its adjustable top tray and lift plate bring every cone in the batch to a uniform fill weight as material settles into place, so operators load a full tray and fill it in one pass.

Built in the USA from stainless steel and aluminum, the machine fills 72 or 143 pre-rolls per run in 30 to 45 seconds and fits 84mm, 98mm, and 109mm cone sizes, making it a fit for shops scaling batch production without adding pre-weighing labor.

Key Features & Benefits

• 72 or 143 Pre-Roll Capacity — fills a full batch in 30 to 45 seconds per run.
• Adjustable Top Tray and Lift Plate — brings fills to a uniform target weight up to 1.2 grams without pre-weighing.
• Stainless Steel and Aluminum Build — built in the USA for repeated production use.
• Fits 84mm, 98mm, and 109mm Cones — covers the common pre-roll cone sizes used in production.
• 1-Year Parts and Labor Warranty — covers the machine through its first year of production use.

Who Should Use the Mini-RocketBox Plus+

This machine fits operators filling pre-roll cones in batches who want a consistent fill weight without pre-weighing material before each run, whether that's a single tray a day or several runs in a shift.

Frequently Asked Questions

How many pre-rolls can this machine fill at once?

72 or 143 pre-rolls per batch, depending on the tray configuration used. Either configuration fills in roughly 30 to 45 seconds per run.

Do I need to pre-weigh material before filling?

No, the adjustable top tray and lift plate bring every cone to a uniform fill weight as part of the fill cycle. That removes the pre-weighing step most manual and semi-automated setups still require.

What cone sizes does this machine support?

84mm, 98mm, and 109mm pre-roll cones, which covers the sizes most commonly used in commercial pre-roll production. Switching between sizes doesn't require a separate machine.

What is the maximum fill weight per cone?

Up to 1.2 grams per cone, with normal fill variance across a batch. Operators can adjust the top tray and lift plate to fine-tune the target weight for a given cone size.

What warranty comes with this machine?

A 1-year parts and labor warranty that covers the machine through its first year of production use. STM Canna supports the machine directly rather than routing warranty claims through a third party.

Where is this machine built?

In the USA, using stainless steel and aluminum construction sized for repeated production runs. STM Canna engineers its equipment in-house rather than importing pre-built units.
