Grid for Yongnuo YN 300 Air II photo light

This is a simple grid adapter / addon for Yongnuo YN 300 Air II light source (might also fit others with the same dimensions). It narrows it's original flood light to 45-ish degrees in front of the device. The idea was to have such lights shining directly on my face (since I work with video calls) and preventing light spilling everywhere else in the room. 

Since my printer is A1 Mini and the grid is almost 200mm wide, I needed to be creative here and I have cut it somewhere and print it in two parts. Then I've glued them together.

Installation: the grid fits the lamp with small maybe 0,5 to 1mm gaps (better to have some play than to not fit at all). Because the lamp doe not have any edges to attach the grid, I didn't include any mounting clamps and used simple yet very powerful black duct tape / electrical isolating tape / gaffer tape that way, that half of it is on the frame and the other half wraps on the rear cover of the lamp.
