Before you buy.
What is the difference between STL and STEP?
An STL file goes straight into your slicer to print. A STEP file can be edited in CAD software such as Fusion 360, Onshape and FreeCAD. If you plan to change dimensions, choose the “STL + STEP” option.
Can I use the files commercially?
The standard license covers personal, educational and research use. Selling printed parts or using them in client projects requires a separate commercial license, which is not sold on the site. Describe your use case via our contact page and we will prepare a custom quote. Details are in the license terms.
Which printer can I use?
The parts are designed for desktop FDM printers. The cycloidal discs are printed in PETG, the other parts in PLA. Settings and part orientations are explained in the printing guide.
Are refunds available?
For digital products, the right of withdrawal legally ends once the download starts, and you confirm this at checkout. If a file is faulty or the content does not match its description, contact us and we will fix it.
Do I pay again when a new version comes out?
Fixes to the same version are free; you download them again from your account. Major versions redesigned from scratch (for example v2) are released as separate products and must be purchased again. The control software is the exception: buyers receive software updates free of charge.
Can I get an invoice?
For purchases in Türkiye, an e-archive invoice is emailed to you automatically. For international purchases, Polar issues the invoice, and tax calculated for your country is added at checkout.
