Buddy of mine wanted a hitch cover for their Ford ST. Mashed a couples things together and here we are!! When I printed it on my ender 2 pro, I used a slight offset on the ST insert, I believe I did 0.2mm. It may not need to be done on a Bambu. I used PETG, but can be done with ABS as well I am sure, but I did not use supports with PETG. ABS would probably need supports.
