If only one rod is slightly longer/shorter then it will lead mostly to head rotations. These will not have significant impact on bed levelling but will have impact on XY error. Since your pair of diagonal rods is not too near to each other then one diagonal rod error should not amplify much.Quote

the diagonal rods are all the same length to 0.02mm, except one of them that has a difference of 0.05mm to the average

// Horizontal offset of the universal joints on the carriages. (This is measured from the edge of the M6mm Rod to the cent of universal joint, 14mm on Mini Delta (3DR) #define DELTA_CARRIAGE_OFFSET 14.0 // mm // Was 25.0 // mm This you may need to change if you are using a different linear bearing / rod size / bushing / or a modified carriage design. If not, 14.0mm should be correct for 3DR using normal carriages and LU6UU bearings.code source

First thing is to tell your slicing software to position the parts at 0,0 (not at 100,100 like many cartesian printers with 200x200mm beds).
But when you home your printer x and y should be at 0,0.... what firmware are you using? have you tried starting with Richard's?

moreover, it's missing the 1.28 mm flat part around the orifice, so it practically ends with a sharp point with a flat of only 0.7-0.8mm diameter.Quote
reprap.org, chapter 8.2.2
Nozzle orifice length
Mk IV hot-ends (up to the middle of May 2012), and earlier models, had a nozzle orifice length of approximately 1.25mm.
Mk IV hot-ends (after the middle of May 2012) and Mk V hot-ends have a nozzle orifice length of approximately 0.50mm.
Note: Due to the nature of 5c collets, the nozzle orifice length can vary as much as 0.25mm.
