Seek Thermal Nano 200&300 Macro Lens Holder

Since Seek has set a high price for their silicone lens holder, I designed a holder for a standard ZnSe lens to inspect PCBs.
Lens specifications:
Diameter: 12 mm
Focal length: 50.8 mm
Purchased from: Aliexpress
The thermal image was taken from approximately 6 cm away.

Printing details:
Material: ABS plastic
Layer height: 0.2 mm
Nozzle diameter: 0.4 mm

The lens cap fits tightly into the holder, so no glue is needed.
