What counts as one design
One part, one set of numbers.
A design is the part plus its sizes and options. Your printer, fit profile and material aren’t part of it, so recalibrating never costs a thing.
Always free
- Re-downloading a design you own
- The other format (STL ↔ 3MF)
- Single parts of a multi-part design
- Exporting again after you recalibrate your fit
- The Fit-Test Coupon, always
A new design (1 credit)
- A different part
- Changing a size, hole count or layout
- Changing an option (mount, floor, lid…)
On Unlimited or Lifetime, new designs are included.
FAQ
Money questions.
No. Credits never expire.
One part with one set of sizes and options. Re-downloading it, switching between STL and 3MF, exporting single parts, or exporting again after you recalibrate your fit are all free. Change a size or an option and it’s a new design.
Yes. Selling printed parts (at a frag swap, online, anywhere) is allowed. Redistributing, uploading or reselling the STL/3MF files is not.
Unused credit packs can be refunded within 14 days. Unlimited cancels anytime and runs to the end of the month you paid for. Lifetime can be refunded within 14 days if you’ve exported fewer than 3 designs.
No. Designing, the 3D preview and share links are free with no account. You sign in when you export: the Fit-Test Coupon is free with a free account and never uses a credit, and your first 2 exports of other parts are on us.
