Telescopic cylinder of scissor mechanism

Input: magenta screw.
Two blue lower short bars are pivoted on the white base cylinder.
Two blue upper short bars are pivoted on the green top cylinder.
Two brown upper short pins are fixed to the jade cylinder.
Two brown lower short pins are fixed to the yellow cylinder.
The cylinders enable the scissor mechanism to move stably in the vertical direction despite the gaps in its revolution joints.

Good morning from Egypt...that's do good things very thanks

[RomainR]

Each Time it’s amazing! What an imagination!!!

[battleforevermore]

At near full extension, wont twisting would jam it?

[SCOP_]

Why not connect the scissor lift on every joint to make it more stable?

[Jay-Dub-Ay]

Would it be better to rotate one of the inner mechanisms 90 deg from the other one? In my head, it would be more stable? 🤷‍♂️

[johntitor]

Please make an animation video about "Spiralift" system. and linear actuator "kataka".
Thanks so much.

[etqanalquran]

very nice work. can you sharing the file with us?

[ReavoEnd]

Is it possible to mechanically simplify this? I want to create 2-3 nested cylindars that telescope from 3mm or 4mm tall to roughly 10mm tall. This would be driven by a twist of the outermost ring.

[Martin]

I cant open the files in Inventor 2020. What version do you use please?

[MrvinTv-ifvb]

Woah may I ask what app you use in making this 3ds

[viniciusbarnabe]

What program do you use to do 3D modeling and animation?
