A client asks for a parametric model, a hobbyist wants a print-ready STL, an architecture firm needs a detail block — and the file itself is finished. What's usually missing isn't the CAD work, it's a clean way to get paid for the file that doesn't involve either a marketplace taking half the sale or emailing the file first and hoping an invoice gets paid afterward.
CAD marketplaces (TurboSquid, CGTrader, CADasbuilt, and similar) exist for discovery — they're useful if you want strangers finding your work through search. But they come with real costs: commission rates from 15% up to 50% depending on exclusivity terms, approval queues before a file goes live, and payout schedules you don't control. For direct sales — a client who already found you, a repeat buyer, a link shared in a CAD forum or Discord — a marketplace is the wrong tool. This guide covers how to sell a CAD file directly, securely, without giving up a third to a half of every sale.
Key Takeaways
- CAD and 3D model marketplaces typically take 15-50% commission depending on exclusivity and sales volume — a direct payment link charges a flat 2%, capped at €25 per sale
- PayRequest Upload accepts DWG, STL, OBJ, FBX, GLB, and GLTF natively — no zipping required for these formats
- The file stays locked until payment clears — there's no "send the file, invoice after" gap where a buyer could walk away without paying
- For CAD formats PayRequest doesn't accept directly (STEP, IGES, native SolidWorks/Inventor part files), zipping the file first works the same way
- A preview render or screenshot as the product thumbnail lets buyers evaluate quality without exposing the actual editable file
Why Marketplaces Take So Much From CAD Sales
CAD and 3D model marketplaces bundle two different services into one fee: hosting/discovery (buyers searching the platform find you) and payment processing. The problem is you pay for both even on sales where you didn't need the discovery — a returning client, a link shared directly, a referral from another buyer.
Non-exclusive listings on major 3D marketplaces commonly pay out 40-60% of the sale price to the creator — meaning the platform keeps 40-60%. Exclusive arrangements can push your payout rate higher, but only in exchange for not selling that model anywhere else, including on your own site. Smaller, niche CAD-specific marketplaces often advertise more creator-friendly splits (up to 50% revenue share), which still means giving up half of every sale for files someone was often going to buy from you directly anyway.
If you're trying to reach buyers who don't know you exist, a marketplace's search traffic has real value and the commission is arguably a fair trade for it. But a huge share of CAD sales don't work that way — a client commissioned the model directly, a buyer found you through a portfolio site or forum post, or someone's a repeat customer from a previous job. None of those sales needed marketplace discovery, which means none of them needed a marketplace's cut either.
How to Sell a CAD File Directly and Securely
PayRequest Upload turns a single CAD file into a payment-gated link without a marketplace account, an approval queue, or a payout threshold to hit before you see your money.
Go to payrequest.me/upload and drop your file. DWG, STL, OBJ, FBX, GLB, and GLTF are recognized directly and categorized as a 3D Model. For formats outside that list — STEP, IGES, native SolidWorks or Inventor files — zip the file first; PayRequest only checks the outer archive, not what's packed inside, so this works identically.
Before publishing, add a render, screenshot, or wireframe view as the listing's preview image so buyers can evaluate the model without you having to hand over the actual editable file first. Then set your price — any amount, in your account's currency.
Generate your payment link and share it wherever the buyer already is: a direct message, a forum reply, an email, a portfolio site. There's no approval wait and no marketplace review process between finishing the file and being able to sell it.
What Happens After Payment
The file unlocks the moment payment confirms, delivered through a tokenized download link rather than a static, forwardable URL. If you're selling to a client under a specific scope — say, a single license for one project — you can cap download counts so the file isn't silently redistributed to a second buyer under the same link.
A single CAD deliverable is often more than one file — the model itself, a rendered preview, a technical drawing, texture maps. Zip them together into one archive and sell the bundle as a single download; buyers get everything in one purchase rather than juggling several separate links.
CAD Marketplace Commission Comparison
| Platform | Typical creator payout | Approval required? | Payout schedule |
|---|---|---|---|
| TurboSquid (non-exclusive) | ~40% | Yes | Platform schedule |
| CGTrader (non-exclusive) | 60-85%, scales with volume | Yes | Platform schedule |
| CADasbuilt | Up to 50% | Yes | Monthly |
| PayRequest direct link | 98%, minus 2% capped at €25 | No | Instant, your own account |
The commission gap compounds fast on higher-value CAD work — a €200 architectural detail pack loses €80-120 on a 40-60% marketplace split, versus a flat €4 (capped at €25 regardless of price) through a direct link.
Frequently Asked Questions
Use a payment-gated link so the DWG, STL, or STEP file only unlocks after payment clears, instead of emailing the file first and invoicing after. PayRequest Upload generates that link directly from your CAD file in under a minute.
Yes — most CAD and 3D model marketplaces take anywhere from 15% to 50% depending on exclusivity and your sales volume. A direct payment link charges a flat 2%, capped at €25 per sale, regardless of how much you sell.
DWG, STL, OBJ, FBX, GLB, and GLTF are all natively supported by PayRequest Upload — no zipping required. For formats like STEP, IGES, or SolidWorks part files, zip the file first and upload the archive.
Yes. Zip the files into one archive and upload the zip — buyers receive the whole bundle as a single download after payment.
Add a preview image, render, or screenshot as the product thumbnail so buyers can see what they're getting. The actual CAD file itself stays locked until payment confirms.
Bottom Line
Marketplaces earn their commission on discovery, but a large share of CAD sales — direct clients, repeat buyers, forum and Discord referrals — never needed that discovery in the first place. For those sales, a direct payment link keeps 98% of the price instead of handing 15-50% to a platform, with the file staying locked until payment actually clears.
