This is the basic fishing V front rod rest. It's made out 2 parts - rod rest with hexagonal hole and threaded insert that's glued into the hole. Thread is BSF 3/8 which is standart for fishing poles.
If you face some problems I recommend printing both pieces separately so thread is nice and smooth with print setting bellow.
Material should be for outdoor use. I used PETG. I recommend 0,2mm QUALITY profile in PrusaSlicer
Print recommendation:
Rod rest
Threaded insert
