I've found great boat https://www.thingiverse.com/thing:3554489 After that I've discovered that I need M3 bolts and nuts. I've followed standards and make a models for M3 bolts 10,20,30,40 mm long. Hex head was used. !!!! NOTE TO READ : THREAD WILL NOT BE PRINTED, YOU NEED TO USE AN M3 THREAD TAP AND DIE!!!! Using tap and die will allow to have clean thread in bolts and nuts. I've added fillets for proper entering of thread cutting tools. For custom length I've uploaded Fusion360 project file. You will need to find in history extrude and change extrusion length. Hope you find it useful.
