Fix grinding of big wheel axle/hobbled bolt #82

Open hlavaatch opened 10 years ago

hlavaatch commented 10 years ago

Fixed hub clearance for 608 bearing on the big extruder wheel axle/hobbled bolt in extras/gregs-wade-v3.scad to stop the bearing hub from grinding the wall and make the axle free to rotate.

Ah i see, so the hole is plugged intentionally? And the user is excpected to dig it out? That sucks. I can do it better with inhole support... I'll do it

It would be best to factor out all the explicit supports and make them optional, to not pollute the final shape with it... Let people use whatever support they want/need...

Okay just did a test print with my "inhole support", and it turned out great. Its sort of a puck with a slot on bottom and a crown of thin support beams that the ridge can be laid onto. When printed I just inserted a table knife into the puck slot and twisted and it snap off cleanly. Any remains of the support lines are easily cleaned off with a flat screwdriver. I will modify my patch to include it later when I test similar approach for the motor mount holes so that they dont have to be plugged as well, factor out the supports and make them configurable (none/bridgy/inhole)
