About this 3D model

Since i bought my X1C with AMS they use a petg spool, but, recently, only sell cardboard spools and i dont trust it fully and dont want my AMS full of cardboard dust or other major issues. Its two Rims that attach to the Sides of the Spool, each Rim weighs around 7g, and i printed it with 870 PLA and 20min to complete it.
