Hello
Have tried in Fusion 360 to reduce the outer diameter of the middle hollow axis by 0.7mm, i.e. from now approx. 16.5mm to new 15.8mm. The inner diameter of 8mm should remain the same.
Unfortunately, I have not managed it :(
Could someone help me and if possible immediately adjust the STL :D
Have the STL (may be changed according to license) and a sketch attached.
Thanks and best
