Sony 50mm Replica (Coin bank, microSD holder...)

Sony FE 50mm f/1.8 Lens Replica – E-mount

3D model of the Sony 50mm f/1.8 lens, E-mount.
This replica was designed to be as close as possible to the real model, with minimal deviations in tolerance & measurements, but generally faithful to the original design.
 

⚠️ Printing Tips

-1- General Parts

Focus Ring:

• To be printed at 0.16 mm with a 0.4 mm nozzle

Front Cap:

• Requires AMS to get the two-color logo
• Only activate classic supports on the build plate
•  Slightly pull the right and left tabs outwards to make the "spring" functional

-2- Choose your lens version

◯ "No Text" Version – Easy (highly recommended)

• Smooth body, no inscription
• Nozzle: 0.4 mm – Layer height: 0.16 mm
• Optional: AMS for gray base + color customization

◎ "Contour Text" Version – Medium difficulty

• Text in contour extrusion (relief)
• Recommended nozzle: 0.2 mm (possible with 0.4 mm, but requires testing)
• Layer height: 0.16 mm or less
• AMS required for multi-color printing

○ "Negative Text" Version – Difficult

• Text in engraving (material removal)
• Recommended nozzle: 0.2 mm, ideally 0.08 mm or 0.06 mm
• AMS required

◉ "Thin Positive Text" Version – Difficult (test only)

• Text in fine extrusion (material addition)
• Nozzle: 0.2 mm required – ideally 0.08 or 0.06 mm
• AMS required
   

🧪 Below are tests carried out with a 0.4 mm nozzle on an 85mm replica: acceptable but limited results.
(As soon as I receive my A1 with a 0.2 nozzle. I'll start testing)
