My FUJINON-EX 135mm F5.6 was fortunate enough to include a metal mount (53mm,P=0.75,Number of screws:6).
To use this with the Intrepid 4x5 enlarger, I designed this linhof lens board.
The original linhof lens board is the work of N_Defrance. I would like to thank N_Defrance.
I divided the parts into two parts. You can print without support.
I fixed two parts and mount with screws (M2.5x10mm) and bolts. No glue is needed.
I purchased the screws from Amazon.co.jp. (They do not sell them in small quantities and there is a large surplus of screws)

[Note]
I know that Nikon has lenses with the same mount (such as EL-Nikkor 150mm F5.6), but I am not sure if my work will work.
I have looked at the Nikkor photos, and it seems that the Nikkor has a different number and location of screws than the Fujinon. Maybe my parts will not work for Nikkor.
