Under what license are your 3D models?

Hello Pololu-Team,

i plan on using your VL53L1X sensor breakout in an project.
i plan to release this as ‘open-hardware’ under CC BY.
i am allowed to in-cooperate your 3d step file into this?
(its all designed and constructed in FreeCAD)
do i have to make some attributions for this used file?

i have not found any information on your site regarding this - but it could happen i have just overlooked it…

sunny greetings
