Video B4 Lens port cap

Creation quality: 5.0/5 (1 vote)
Evaluation of members on the printability, utility, level of detail, etc.

3D model description

Several versions included, with or without 'B4' text.
Original B4 mount flanges appear to be 2mm thick.
The included STLs (v1..) flanges are 1.98mm.
If you print with an FDM printer the flanges may come out thicker (depending on layer height).
STL v2 flanges are 1.78mm by design and so should print thinner.
I think the one or two I printed for myself have been tight.
If this is the case, either (in the slicer) you could reduce the height by 1 or 2%, or I've now added v3 with 1.5mm thick flanges.

3D printing settings

For FDM printers, support is required (because of locating pin on rear).
v1.1B can be printed without support, but the locating pin is a separate print.
Typical print time (Cura, support touching build plate only, v1.1) 35min @.2 layer height.
