About this 3D model

I needed more spindles for my Singer sewing machine, so I designed and printed my own. Parts A and B snap together (glue is optional), if your printer tolerances are close to mine. I used clear PETG. I have used this design for a while now and it has worked flawlessly. Later on, I noticed that the spindles were bouncing all over in my sewing spare part kit, so I made a holder for six spindles.
