I made this for my Mom for her Black+Decker Handmixer model: MX3200B after she was unhappy with how it never quite sat upright, and recently someone else with the same model had the same issue so I thought I better post this incase others want this glue on upgrade. It blocks no vents and had very little impact on useability beyond it being able to sit it up without it falling over. Hope this helps someone!
