ROBO3d Bed Leveler ~Revised by Tesseract

Last crawled date: 4 years, 1 month ago
The solution for bed leveling with no loss in bed height
It is very simple yet very effective it is simply two hollowed out shafts that slide inside each other that the screw can pass through each shaft has a 2mm base or cap for support the key thing here is that there is an internal spring that pushes the two shafts apart.
as can barely be seen in the images
The problem before with just springs is that they generally have no horizontal support and could allow the bed to shift as the bolt tips the intermingled shafts help prevent this.
This was actaully but together with a spring from a pen but was designed for use with a spring from MCMaster-Carr but could be used with similar springs else where.
The important specs:
Item: Metric Compression Spring
Material: Music Wire,
Length uncompressed: 19mm Overall,
Diameter: 9mm OD,
wire width: 1.00mm Wire-WOW nice and thick should make it stable horizontally
compressed height: 7.5mm
so fully compressed the height will be 11mm current height is 12mm it expands about 8-9mm but you should not need nearly this amount.
The McMaster Carr product number is: 94125K633
and the link is: http://www.mcmaster.com/#94125k633/=p19bik
the cost for the springs is just over $10 for a 5 pack but should be extremely stable in the horizontal plane
The current shaft will have to be removed in order to implement this leveler as the new shafts take its place.
Have fun.
I am glad that so many people are printing these things out and using them I just added another it is called robolevel7mm.stl , it is very similar to the original. The only difference is the smaller piece only has a 7mm hollowed out section to allow for a 7mm spring as the 9mm may be hard to come by still focus on 1mm wire size and the rest of the specs as close as you can to get optimal use
I just uploaded the netfabb repaired version for both groups because I think something happened to the originals as some were having trouble with it, sorry if this caused any inconvenience.
