Printer Z Layer Calibration Test Bracket

Hey, This is my first published model, I made it to test out my new Bambu Labs X1 Carbon with PETG. I had some layer adhesion issues prior to buying a textured PEI bed for it. The print is designed to test layers. I imprinted a pattern onto a generic bracket to test this, the model above was printed at standard speed 0.16mm layers White Overture PETG 1 Hour 8 Minutes. Hopefully someone else can find this model helpful, I also included a STEP file for anyone who for any reason wants to modify or reuse this model. Thanks for reading!
