Boost MeDo you like this model? If you like, support me and help me create more great models!

This is a smaller version of my original hydraulic valve knob for hydraulic bottle jacks like the ones from Harbor Freight

 

This smaller size valve knob allows for the bottle jack to be used directly on the floor or other flat surface.

you should also print one of my quick handles for your personal bottle jack equipment.

more walls more stronger at least 3, I put 7.

PETG, PLA is ok too.
