Bed Leveling Tool

23/07/2018 Today I added another video showing the precision of this tool's accuracy. The 1 mm space between arrows on mirrored wing-like scales is actually in a 5:1 ratio in reality, which explains why arrows are most precise in horizontal positions. That's why I suggest calibrating bed level in this position. Most of the time I print with 0.5 nozzles, so objects are designed to fit the resolution of details that 0.5 nozzle can provide. Today I also deleted a previously uploaded not-tested 2020 aluminum profile adapter. Since then, I've been able to find some pieces and test it. Unfortunately, it was no good, which is why I drew a new one. To make it strong, I printed it with many walls. The easiest way to attach it on the 2020 frame is to rotate it on, so I cut it and put some fillets from the sides. 16/7/2018 This tool is designed and used by me to level my bed when needed on my GEEETech i3 3D printer. It's used for "fast" leveling or checking if the bed is still leveled evenly. The tool is attached to both two 8 mm rods that the extruder rides on. The bottom part of the tool sticks to the rod, while the top one is movable so it can be adjusted if your distance between the 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 a small round pile and 1.5mm drill bit for removing support from holes. I used the pile only to make fillets, making it easier to insert filament pieces into hole axes of moving parts. Additional parts needed for assembly include an M3 screw, M3 washer, M3 nut, small length of 1.75mm filament, and a rubber band (Loom bands). I used black permanent markers to color scale stripes. I also uploaded a video with useful and not-so-useful information about this model. I suggest watching it if you have any doubts or questions... Assembly: "Main Slider.stl" is slid and screwed onto "Base.stl" using an M3 15mm long screw. The screw, nut, and washer are some of the leftovers from my printer's assembly. "Fixed Slider.stl" is slid into "Main Slider.stl". I used a black Loom band on model anchors. "Left Arrow.stl" and "Right Arrow.stl" are fixed onto "Fixed slider.stl" and "Main slider.stl" using three pieces of 1.75mm filament. Moveable "Rod Sslider.stl" is slid into the back side of "Main slider.stl". A bump at the bottom part of "Rod slider.stl" prevents it from freely falling out of "Main slider.stl". Parts need to be moved up and down manually a few times to make them run smoothly... I also added some test files for moving and snapping parts of the model. Usage: Choose one place on the bed (center or some corner) and attach the tool to both rods. Then, unscrew "Main Slider.stl" and screw it back after you move it to the bed so that "Fixed Slider.stl" is pushing against the bed and the scale is aligned at a chosen point. Now all you need to do is move the bed and reattach the tool to adjust the height of all corners of the bed to the same scale point you chose in the previous calibration step. https://youtu.be/KKVZionPe8E https://youtu.be/eFlLIdxJpXk
