Z axis Lift (Prusa i3 Pro B)

These are to be used for maintenance on the hot end and for when you need to clean and regrease the rails, you will need the anti-wobble brackets fitted to your printer they are made by JimmyShawsTidbits

There are 3 different designs a small base and a wide base and an extra wide design to withstand the abuse of changing a nozzle and heavy handed people :)
