This model was designed to fit a 4160 750 cfm Holley carb with a choke horn. It should fit any 4150/ 4160 carb with no issues and may also fit others. I used a cheap carb stud from amazon cut down to hold it during storage.
If printed with a .4mm nozzle and 4 perimeters with 40% infill the vertical walls will be solid and the top should be plenty strong. No support needed can use a brim but shouldn't be necessary.
The author marked this model as their own original creation.
