Took inspiration from Makoki_63:

Created this for Zonestar P802QA printer.
Requires two 8x16x5mm ball bearings, four M3x10mm cap screws, washers and nuts.

I got the ball bearings from http://www.aliexpress.com/item/688-688-2RS-688-RS-L1680-8x16x5-mm-2016-new-coming-shoe-bearing-usded-for-toy/32479708451.html

Mount brace with bearing onto z-axis sliding rod and screw rod.
Move x-axis near the top before marking holes for M3 screws.
Drill holes
