Overview:

I saved the cart from an old grill and filled the center sections with bracing and a melamine board. This worked great to put our little pizza oven on.  Unfortunately, one day as I wheeled it out from the garage, I hit a bump and the pizza oven fell off and cracked the stone. 

I designed these brackets to slip onto the feet of the oven and secure the unit to the cart with screws. Due to the angled legs, these brackets anchor the oven securely to the cart.  They work great, and I haven’t had to worry about breaking another stone.

I’ve added my Fusion 360 file, so you can modify it as necessary.

Printing:

I printed mine in PLA because it mostly sits indoors.  Otherwise, I would recommend ASA.  No supports required.
