Ryobi T42Li 80V Tractor Compatible Seat Bracket

This is a replacement seat bracket compatible with Ryobi 42" 80v riding mowers. I've not had a chance to test it beyond sitting on it and trashing around. I'll report back after a mowing season. The print quality doesn't look great because I used a .6mm nozzle with .48mm line height to print it fast (and hopefully strong) I only used 4 walls. It is printed in cheap PETG from amazon. If this one breaks I'll try printing it in a better filament with more walls to make it solid. 
I increased the thickness of the base but I recessed the bolt head so it can use the original bolts while being hopefully a bit stronger.

Edit, Need to print the bracket out of TPU. I tried PLA+ and PETG. Both only lasted a few minutes to a full mowing. The TPU one is going strong after about 3 hours of use.  Only TPU I had is blue.
