EDIT - I've been using these wheels for the past 4 months now and they are a lifesaver. I've releveled the bed a few times during but all of the times it was due to me changing something with the printer or working on it etc. I haven't worked on the printer in about 3 months and haven't needed to relevel the bed a single time, and the BLtouch is always reporting about the same bed mesh. The TL;DR: These work great.
These are some locking bed wheels for the Wanhao (or similar) Duplicator I3. I personally have the Duplicator v2.1 but it will probably work on other models. I wanted some locking bed wheels so the bed wouldn't shift as much between prints because I have a bltouch installed. Supports are required and are a pain to remove but it hopefully shouldn't be too bad. The parts are already oriented correctly for printing (with the teeth facing up on both parts). To adjust you have to squeeze the print surface and the Y-axis plate together to release pressure on the part and then you can turn the wheels. After printing you need to insert 4 m3 nuts, one for each wheel.
Also Printables is a better site please download it from there
