Wanhao Duplicator i3 mini Bed Stabilizer

Z-layer shift is a nightmare waiting to happen with any print on the i3 Mini, but not anymore (ironically I had a few failed prints, printing these parts because the bed shifted again!).

This part has an added ring at the bottom to fit inside the hole around the fastener bolt for an even more stable bed (mine still moved too much in the Y direction with the original part by Chrispy101).
The ring fits nicely around the bolt and into the hole right above the thumbwheel, making this stabilizer very effective.
