Thicken walls of stl file cutter

I have a cutter that I downloaded from Cults3d. I printed it and the cutter doesnt work due to its walls being too flimsy. I tried using cookiecad to thicken walls but the image isnt good enough. Any suggestions?

I have the STL and can send it to anyone that can help. Thanks!

Send it to me at Kristi.bundick@gmail.com. I will be glad to help. I am wondering if it is the file itself. I will run it thru Prusa slicer.
