They’re not alone. 10 of America’s top 20 pre-roll brands run STM equipment. Watch why operators who know the market keep choosing STM.
Inconsistent pre-rolls hurt brand quality with loose packs and canoeing
High labor costs compress margins as wholesale prices keep dropping
All-in-one machines lock you in – can’t adapt or scale as your operation grows.
Missing the infused market means missing 44% of all pre-roll sales
Daily output depends on the specific machine model:
*Mini-RocketBox+: Produces up to 1,250 per hour or 10,000 per day with a small crew
*RocketBox 2.0: Produces up to 2,500 per hour or up to 20,000 per day
*RocketBox Pro: Produces up to 5,000 per hour or up to 40,000+ per day using a continuous workflow
The new 2026 Atomic Closer can crown up to 34K a day
YES. A single full-time employee hand-rolling joints costs a minimum of $28,800 o rm per year, whereas an automated machine can speed up production by 12x or more, often delivering an ROI in just 3-6 months.
Automation eliminates the “hidden costs” of manual labor, such as production bottlenecks and inconsistent pack quality
All RocketBox models use STM’s proprietary nitrogen-filled airbag system, not mechanical tamping like KnockBox or King Kone. This creates an even, fluidizing vibration that fills cones without gaps, while the adjustable lift plate ensures proper density at the filter and volumetric metering via the top tray delivers consistent, accurate target weights.
STM machines are compatible with standard 70mm Dog Walker, 84mm (1-1/4″), 98mm (Special Small), and 109mm (King Size). Other types sizes available on request.
The Mini-RocketBox+ is up to 5× faster than the Knockbox (143 joints in <45 seconds vs. 100 joints in 2 minutes). It uses volumetric metering with no pre-weighing to automatically hit target weights, while Knockbox users often must pre-weigh material or manually fix under-filled joints.
STM’s proprietary nitrogen-filled airbag system replaces simple mechanical tamping for more consistent fills.
Built from American stainless steel and aluminum and manufactured in Spokane, WA, the Mini-RocketBox+ is domestically made—unlike the overseas-produced Knockbox.
Top brands choose modular systems to avoid downtime. If an “all-in-one” machine (like JuanaRoll) is expensive, complicated and if something breaks, the entire production line stops.
With STM’s One-Tray Workflow, stations are independent; if the filler is being cleaned, the closing and infusing stations can keep running, ensuring continuous output at a fraction of the cost.

STM proudly leads by example in customer service, support and satisfaction.
Our highly regarded Client Success Program includes: a dedicated client portal with a range of tools, videos and support documents; a dedicated Client Services representative tasked with providing you technical assistance, virtual training, and in-depth support; and options for On-Site Training.
A One Year Parts & Labor Manufacturing Warranty is included with every machine. We design, engineer and manufacturer our equipment in-house to uphold the utmost quality. As such, new part orders would be ordered from STM directly vs. having to source 3rd party parts overseas or from external manufacturers.
If you’re rolling for personal consumption, you can purchase a pre-rolled joint already filled with ground cannabis or use an empty cone to fill and pack your joint manually. For commercial production, many dispensaries and cannabis processors prefer a pre-roll machine, such as the Mini-RocketBox for efficiency and product consistency.
Payment for all orders is due in full. We offer financing through our partner NEC. We may have other terms and plans available. Contact us.

STM Modular vs. Futurola vs. All-in-One Systems
| Feature | STM Modular | Futurola | All-in-One |
|---|---|---|---|
| Production Capacity | Up to 50,000/day - scale as you grow | 800–1,000/hour, hard ceiling | Fixed ceiling, can't expand |
| Upfront Cost | Start with one machine - add more as you grow | Low entry - limited capability | $200K+ all-in commitment |
| Downtime Risk | One station down - line keeps running | Moderate — parts hard to source | Single failure stops all production |
| Repair & Parts | Built in Spokane, WA - parts ship fast | Overseas parts — long lead times | Complex repairs, costly downtime |
| Training Time | 1 hour per machine - no specialists needed | 1–2 hours basic training | Full days to weeks |
| ROI Timeline | 90 - 180 days average payback period | Varies — limited output caps savings | 12–24 months typical payback |
