Linear bearing housing for 8 mm shaft

This is a replacement for Tronxy z-axis linear bearing housing. Original parts are made from plastic, which is quite flexible and bearings fit a bit loose. So the entire table could change its horizontal alignment from print to print. Especially after parts removal with some force. Easy fix is to get all metal housing linear bearings. I could not find one for 8 mm shaft and decided to print. I used ABS-PA as I wanted to make it hard to avoid as much as possible bearing move against the table. Wo
