About this 3D model

If you own a Leapfrog CreatR this little thing might save your print. It will insure that the filament spool will stay in place on its rotative platform during the print. I just ruined a 8h39mn print in the very last minutes because the spool failed from the rotative platform resulting in no more filament feeding the extruder ! (see photo) And that's because the spool was having just few filament left. Therefore it was not heavy enough to stay in place by itself . Something the Leapfrog team should have think of ! Edited : I also uploaded version 1 because I don't have time to print and test V2, and because I'm sure V1 works well. Please tell me if V2 is high enough. I have a doubt here... Photos are showing V1... V2 vs V1 should - use less filament - be stronger - take less time to print - be as efficient (not tested) Edited October 15th 2013 : I uploaded a V2 version with a 13mm hole as requested by Rene (see comments) because it seems there is also a 13mm bolt CreatR version. Weird... Please visit http://www.reppersdelight.spacymen.com for more information.
