Realistic expectations
Most people who try this earn around $0–$40 per month in the first year; the high figure of $3,000 is a ceiling for a focused solo operator, not a typical outcome. The chance of receiving at least one real payout within six months is rated 4/10. Expect the first payment after 30–180 d.
How it works
You build a model digitally in BrickLink Studio (free), generate step-by-step instructions, and list it as a Premium MOC on Rebrickable. Buyers pay for the instructions and use Rebrickable to buy parts or match their own collection. Payment goes straight to your PayPal or Stripe account; Rebrickable then deducts or invoices its commission (reported 8%/13%/18% by price band on its Designer Plan). Popular MOC designers also get approached by kit sellers for licensing.

Market conditions (Nov 2026)
| Factor | Assessment |
|---|---|
| Demand trend | growing |
| Competition | medium |
| Effect of AI | neutral |
| Price pressure | stable |
| Chance of real net profit within 12 months (≥ $100/month where the plan can pay that much) | 10% |
| Typical net profit at month 12 (low / median / high) | $0 / $25 / $2,500 |
Adult LEGO fans are a growing market; designers with recognisable themes (modulars, vehicles) and good renders sell repeatedly. Kit cloners copying popular MOCs are a risk.
Pricing strategy
Launch at $8-12, raise to $15-25 for large builds; offer alternate builds of popular official sets.
Path to profit
- Month 0-1: design and render 1-2 MOCs (cost $0)
- Month 1-3: list as Premium MOCs; first sales
- Month 3-6: release monthly; $15-60/month
- Month 6-12: median ~$25/month
Business-plan sources:
Payout path
- Methods: PayPal (direct) -> bank, Stripe Connect -> bank
- Minimum payout: None (buyer pays you at time of sale); PayPal-sale commission invoiced monthly once owed > $5
- Frequency: per sale
- Typical delay: 3 days
- Notes: Confirmed on Rebrickable's Premium MOC Fees help page (last modified Oct 2026): the buyer pays the designer directly; Stripe sales have the commission auto-deducted, PayPal sales are invoiced at month end once $5 is owed. Commission: 10%/15%/20% for $1-2.99/$3-19.99/$20+ on Free/Pro (8%/13%/18% on the $9.90/month Designer Plan), plus PayPal/Stripe ~30c + 2.9-3.6%.

Legality & compliance
Legal: MOC instructions are your own work; LEGO's fan policy allows it, but do not use LEGO logos or sell counterfeit kits.
- Compliance requirements: report income for tax; PayPal/Stripe KYC; respect LEGO trademarks
- Platform availability: PayPal works in 45/50 reference countries; users report PayPal/Stripe issues in some (e.g. Ukraine, South Korea).
Risks
- Small niche audience
- Copying of MOCs by kit makers
- Commission terms may change
