I got this from user Omilly at Thingiverse. I shrank it to the needed size and thickened some lines in TinkerCad. After 3 or 4 passes through the PrusaSlicer I got the Gcode I wanted. I printed it on my Mini+using SainSmart TPU in about 15 minutes after I got the temps right. 225 for the nozzle and 55 for the bed. My wife is happy with the result.
