I was doing some suspension work on my 2WD S10 and noticed that the OEM ball joint boot had split. The joint itself was still tight and moved freely so I modeled this up and printed in TPU 95 so I could get things reassembled. 

Dimensions of boot:

48mm base diameter
17mm pin diameter
48mm tall

Print Settings:

0.6mm nozzle
0.44mm layer height
3 perimeters
Print with small side touching build plate to avoid need for supports
