MP Maker Ultimate 2 Nut Driver

This is designed for levelling the bed on a Monoprice Maker Ultimate 2 printer. This is a rebranded Weedo F150S, NOT the same as the old version 1 printer made by Wanhao. This will only work on the Maker Ultimate 2.

The size of this driver flat side to flat side internally is 6mm. The nut I needed to remove said it was a 5.5mm nut which would place the size at either an m3 or an m3.5 depending if you believe the book or the actual size of it. Confusing little nut.

I had some 5.5mm sockets around but none of them were tall enough to deal with the screw coming down through the nut I had to tighten. This thing is way taller than needed but I wanted to be positive it worked and have some room for a grip.

The handle has a slight knurling on it to increase grip.

I have used this same tool now for almost a year and it is still holding up very well with no issues.
