LintRoller —— with bearing

Suitable for a replacement core with a length of 10 cm and an inner diameter of 4 cm.The original roller of the lint remover I bought has very high friction. It always tears a layer off quickly and stops rolling entirely after a short time, which feels very wasteful.So I designed a version using bearings, which rolls very smoothly.It requires two 685zz bearings, each costing 0.5￥, 2￥ totally with shipping.https://item.taobao.com/item.htm?id=775995249778&skuId=5477908571248 The connection between the handle and the bracket can be secured with an M4*15 screw (a slot for a knurled nut has already been reserved). Of course, it's perfectly fine not to screw it in, as it fully meets daily usage needs.
