Fair question
Probably. For hobby prints and novelty items, free catalogs work well. When a part has to perform (carry load, mate with hardware, hold a precise dimension), a near-enough model means printing it again until it fits.
A free STL, in practice
Every StreamSolid model
A single failed print and an evening of troubleshooting adds up fast. One good file pays for itself.
Why sizes, not scaling
Scaling multiplies every dimension at once, including the ones that must not change. On a functional part, that quietly breaks the fit.
An M4 bolt hole, a bearing seat, a threaded insert, or a snap that mates with a real part has to stay its exact size. Scale the whole model and the hole no longer fits the hardware.
A 0.2 mm slip-fit gap becomes 0.3 mm at 1.5x. A press-fit turns loose, or a clearance closes into interference. The tolerance was tuned for one size, not a multiplier.
Scaling up wastes material and print time; scaling down can drop a wall below a nozzle width or under the load it has to carry. Thickness should follow the job, not the whole part.
Chamfers, reliefs, and print-in-place gaps are set for how FDM actually lays down plastic. A blanket scale throws those off, and you feel it on the plate.
So every StreamSolid size is regenerated from the parametric CAD model: the dimensions that should change do, and the interfaces that should not stay put. Pick the real size you need instead of scaling and hoping.
Pro opens the whole catalog for a year. Here is the comparison.
Drawing a functional parametric part from scratch is CAD time, then tolerance work, then test prints until it fits. Pro is one subscription set against however many of those you would otherwise do yourself. You already know what your hour is worth.
Standard sizes are always free as STL. Go Pro and every model, every size, including Custom Size, is yours for the year. Every part arrives support-free and print-ready with a commercial license included, so you skip the design time, the CAD iterations, and the blank sketch.
Join the waitlist for first access and founding-member pricing. Founding seats are limited to 25, annual only, and the price you join at is the price it stays for as long as you stay subscribed.
The standard size of every model is free to download as STL, on the product page, with no account. Browsing the whole catalog is free too.
10 Custom Builds the moment you create an account, no card required. Spend them on any models you like. The standard size of everything else stays free with no account at all.
A one-time purchase that unlocks every size of a single model. You buy it from that model's page, where its price is shown. No subscription, and re-downloads and updates are free for as long as we offer that model.
Unlimited sizes on every model, plus a commercial license, active the moment you subscribe. Roadmap suggestions from a Pro account are marked Pro and listed first.
Pro pricing is announced at launch. Create a free account and you will be first to know when it opens.
Prices for new members rise as the catalog grows. Whatever price you sign up at is the price it stays for as long as you're subscribed. Creating a free account puts you first in line for launch.
Yes. Day one you get commercial rights, unlimited sizes on every model, your license PDF, and Pro-marked suggestions at the top of the roadmap. Whatever price you sign up at is the price it stays for as long as you're subscribed. Prices will increase as the catalog grows.
Yes. Choose a model and a size, and a professional print farm in the USA prints and ships it to you. You see the price for that exact part before you order. It needs no account and no unlock, because you are buying the physical part rather than the file.
No. Every plan delivers print-ready STL. Custom Size is how you get an exact size without touching CAD: set the dimensions you need and the model is built to order.
Yes. A Pro subscription includes a commercial license that covers commercial, bulk, and wholesale use of your Pro downloads. Free and one-time-unlock downloads are for personal or internal use (not for selling printed parts), and the files themselves may not be shared or resold.
