Wally Custom Duplex Plate - Jumbo Plus

I used Normal EufyMake (previously AnkerMake) settings for PLA+ and didn't need to make adjustments.
Make sure printer's Z gap is dialed in or the surface could get marred.

I took Jumbo and scaled it up so the final area of the plate is about 3.75" by 5.5", then adjusted the holes to fit.
