Microscope Lens Eye Piece ~30mm (29.6 ID)

I saved an old microscope from the trash, and it needed some parts to get working again, including a replacement eyepiece. Eyepieces are important to keep the correct eye distance from the lens, and I found these vintage ones hard to replace, so I designed a printable version. I added 11mm in length to cover the top of the lens tube, which adds stability, improves the look, and provides extra protection.

The default printer profile has ironing enabled to smooth the top layer, so I didn’t find extra sanding necessary. I’ve also included a 'regular length' option if you prefer. Printed in PLA+, the fit is snug on my machine, but if you experience shrinkage, try scaling up by 1-2% in your slicer for a better fit
