Deltaprinter bed leveling system

Firstly, before you get exited - THIS THING IS A WORK IN PROGRESS AND DOES NOT WORK as supposed. Check out my working Delta leveling system: http://www.thingiverse.com/thing:2124667 Print Settings Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2 will be good Infill: 100% Notes: I printed 100% infill, because I wanted it to be strong as hell. :D Post-Printing For a long time I have struggled to get my Delta endstops right and bed leveled. Then my lab bought UM2 printer which had this rather nice bed levelling system with springs and I thought it would be rad if could level my Delta same way. How I Designed This I planned to use my purple hexagon shaped heated bed as a levelling platform, it even had holes in the right places. I printed out six pairs platform supports and thumbwheels (http://www.thingiverse.com/thing:641854). From one of my previous project I happened to have a assortiment of springs (form ebay: http://goo.gl/2nZCJ9) where I got suitable springs to support the platform. For fixing mounts to the heated bed I had to use common M3 bolts, nuts and washers, mainly because the holes in the purple hexagonal heated bed were about that size and I did not want to drill them to bigger size. And finally you will need 6X M4 bolts and nuts for mounting it to the printer frame. Custom Section When everything was assembled and mounted on the printer I found out the harsh truth - heated bed does not slide very well with the threaded M3 bolts and gets often stuck. That caused some bending of the pcb (heated bed) so the outcome was even more distorted heated bed. So I scrapped the project and moved back to old heated bed holders. Future perspective would be to design this thing with only three levelling points and hope it would work better. Some time later I discovered this amazing webpage which makes levelling your Delta a piece of cake even without any bed levelling option: http://escher3d.com/pages/wizards/wizarddelta.php
