TPU Retraction Test

This is my TPU retraction test. There are many like it but this one is mine.I was trying to calibrate 75a TPE for my drag racer tires and standard retraction models were not cutting it for me. So i hopped into cad and made this little thing up. Print it, check for excessive blobs or pock marks, adjust settings, repeat.Easy. I was able to calibrate the TPE to print a significantly nicer model in ⅓ the time of the first tire.
