Today I added another video in which I try to show the extend of accuracy that this tool provide. I did not mention yet. Space between arrows on mirrored wing like scale present 1 mm in reality. They are in aprox. 5:1 ratio. Arrows are most precise in horizintal position. That why I suggest to calibrate bed level in this position.
Most of the time I print with 0.5 nozzles. That why objects are designed to fit the resolution of details that 0.5 nozzle can provide.
Today I also deleted previous uploaded of not-tested 2020 aluminium profile adapter. From then I was able to find some pieces and test it. It was no good. That why I draw a new one. I printed it with many walls to make it strong. The easyiest way to attach it on (2020 frame) is to rotate it on. That why I cut it and put some fillet from sides.

This is tool that designed and that I use to level bed when I need to do that on my GEEETech i3 3D printer.
It is used for âfastâ leveling or cheking if bed is still leveled evenly.
Tool is attached to both two 8 mm rods that extruder rides on.
Bottom âstick to rodâpart of tool is fixed, top one is moveable so it can be adjust if your distance between top and bottom rod is different.
After cleaning support from printed parts they all need to be assembled together. I printed them with brim so I had a little more cleaning to do. I also helped myself with small round pile and 1.5mm drill bit for removing support from holes. I used pile ONLY to make fillet and that way the insertion of filament pice to hole axis of moving parts easier.
Additonal parts that are needed for assembly are:
M3 screw, M3 washer, M3 nut, small length of 1.75mm filament and Ruber band (Loom bands).
I used black permanent marker to colour scale stripes.
I also uploaded video with useful and not so useful info about this model. I suggest to look at it if you have any dubs or questions...
Assembly:
âMain Slider.stlâ is slided and screwed with M3 15mm long screw on âBase.stlâ.
(Screw, nut and washer are some of leftovers after assembly of my printer)
âFixed Slider.stlâ is slided into âMain Slider.stlâ. I used black Loom band on model anchors.
âLeft Arrow.stlâ and âRight Arrow.stlâ are fixed on to âFixed slider.stlâ and âMain slider.stlâ with 3 pieces of 1.75mm filament.
Moveable âRod Sslider.stlâ is slided at back side into âMain slider.stlâ. Bump at the bottom part of âRod slider.stlâ prvents it to freely fall from âMain slider.stlâ.
Parts need to be moved up and down manualy few times to make them run smoothly...
I also added some TEST files of moving and snapping parts of the model.
Usage:
You choose one place of the bed (center or some corner of bed) and attach tool to both rods.
Then you uncrew âMain Slider.stlâ and screw it back after you move it to the bed so the âFixed Slider.stlâ is pushing against bed and the scale is aligned at some chosen point (picture X).
Now all you need to do is to move bed and reattach tool to adjust hight of all for corners of the bed to the same scale point that you choose at previous âcalibrationâ step.
