Tulp like Windmill

I made a tulp like windmill which consists of two parts. Pease add some 16/8/5 (outer-/inner diameter/height) ball bearings. → link https://de.aliexpress.com/item/1005005321486587.html?spm=a2g0o.order_list.order_list_main.91.b0e65c5fQ1EIjQ&gatewayAdapt=glo2deuThe design is a "press" fit" so just press the bearings into the prints.For the stand I use a 8mm threaded stainless steel rod. (You can find them ob ebay for a few euros) I use white and yellow PETG.
