Massey Ferguson 390 Bonnet Latch and Knob

thingiverse

This is a replacement Knob and Latch for a Massey Ferguson 390 tractor bonnet. The original knobs and latches for these tractors are either not available anymore, or they are very rare and hard to find. I created these solid models myself and am happy to share. I split the knob in half so that it could be printed without support materials. The 2 halves can be glued together. I added shallow holes to allow for dowels for alignment. The latch was also split to make it easier to print and they can be glued. However, once these are installed on the tractor and snapped together they will hold themselves together. I used PLA for mine with 30% infill and they seem to be very strong. If you happen to use this design, please message me to let me know how it works for you. Thanks, Jim
