A little bit simplified models of pneumatic car jacks in deflated position. I tried to keep dimensions of the real ones, but to make it printable I had to be creative in some parts. It will look good in a corner of car workshop diorama after some painting.
I was able to print them without issues on my Prusa Mini+ with 0.1 resolution and 1mm brim. Brim is a little hard to get rid off, but with some patience and clippers it's not a real issue.
The author marked this model as their own original creation.
