Offset Z-Lead Screw Bearing Holder

<B>OFFSET Z LEADSCREW BEARING HOLDER</B> My Creativity ELFPRO CoreXY printer has stock Z-axis lead screws which are 405mm long. I replaced them by other ones with different pitch and a standard length of 400mm. This is too short for the stock bearing holders, so I replaced them with this thing. It has about 10mm down offset and a recess for a 608 ball bearing (8x22x7mm). The original screws can be used for assembly. The part should be printed with the bearing side down and needs supports under the screws side. In case you want to use it for another 3d printer with 20x20 aluminium profile: the distance between screws center and ball bearing center is 40mm.
