Zippy 3s 3000mah lipo battery case

My Lipo was getting bumped around in my RC car so i wanted to make it bigger while protecting the battery. The whole in the top were originally for zip ties to hold the battery in place but the head would protrude. I just didn't use one because it was a snug fit and it stayed in fine. I used PLA and printed it upright. Here is one i bought https://www.ebay.com/itm/New-Zippy-3000mAh-3S-11-1v-20C-30C-Lipo-Battery-Pack-XT60-XT-60-Flightmax-USA/151692179743?hash=item23518ef91f%3Ag%3AoCoAAOSw3xJVYgwL
