I made a sturdy tripod plate for my old Cullmann Video 3200 tripod. It's almost like the original plate but without the pin. Use a ¼" photo screw and a washer. I've added also the Fusion360 project and the STEP file in case you have to change something. Printed from PETG with 0.2mm layer height. Happy printing!

Use the 3MF file in Prusa Slicer or increase the perimeters to 5 or 6 and infill to 20%.

outer diameter = 30mm
inner diameter 6.6mm
