Adjustable height jack stand with 5mm stops

I remixed my own creation to add 5mm stop points to the jack. To adjust the height lift up on sleeve and twist. When you're not lifting up the sleeve will catch on the teeth on the stand and stop. Every half turn is 5mm.

The provided STL safely ranges from 80mm to about 140mm in height.

The teeth _will break off_ if you apply force to them. They are not meant to be weight bearing. If you are going to place more than a couple of pounds to this I'd highly recommend using a m3x8 screw to lock the stand in place and take the force off the teeth. Stronger materials like PETG or ABS will increase the durability.
