Hi Bobby, I'm just at the point of printing the center mechanism. And both you and MrBaddeley have some brilliant ideas going into the construction of this particular area. I'm interested in holding off my center leg build until you have released your concept for viewing.
I guess my question is ( No pressure : ) do you have any idea when you will released your findings here?

Hiya, I would hold off at the mo, my design is clunky,slow and puts too much strain on the motor, so I'm going redesign completely. Luckily I designed the whole thing to be removable so easy to swap out. Will keep you posted. Interested in this design

Awesome! I will hold off on the center leg. I tackled the Front skin yesterday and after staring at it for 3 hours, like a jigsaw puzzle, it all started to reveal it self ; ) Will be gluing it up tonight and then on to tackle the rear ; ) As always "thanks again".

No problem my friend, I knew the skins would be the most challenging due to shrinkage and curved / thin print, probably the most challenging print. Easy to design but the problems occur when you print. Too tall or curved and you get waving and warping. Hence the jigsaw puzzle, small and glued is the way forward. Sanding and filling makes a lovely finish which just drops onto the frame, no stretching or gluing in situ.

i have uploaded the 123dx files if you're interested in finishing this design

Hi, Unfortunately i tried with a servo but i'm not satisfied with speed/power. now i stopped working on this project because i have other, more important, things to do than this and i don't know when ill be able to resume working :((

I've had the gear motor strip on my Extruder, so have been down and out the last couple of weeks with out plastic. Just waiting for a replacement motor from China : (
I've been looking at your design of the centre leg and was wondering if it will allow the rods to stay in place between the legs. I see some structural benefits having the legs joined by a central pivotal point. I believe this would also help alleviate any flexing from the legs.

Look forward to seeing your finished result : ) Cheers Jace

Hey yeah, that's fantastic! Great work ; )

3D Printer parts and set up similar to how a 3D printer functions, very cool!

Nice! love it. Do you need to drill / modify the centre leg?

just drill a 3mm hole and use a nail (i left the drill bit inside :)) )
