Description

A 4 part iris mechanism that I tried to make as simple and functional as possible. A cool showpiece to have on your desk or just a fun fidget toy.

Printed with a 0.2 mm layer height, the blades are pre-supported (there's also a non-supported) but might require a brim depending on your bed adhesion I used one with 2 lines of width.
You will need to print 12 blades in total.
The top ring is made to be glued on.

When the model is scaled to 60% of its original scale, it is just the size that can pass through the power plug of the printer (a1mini)

I made a 160% scaled up version to be the lid to our 3D printer trash can. printed perfectly, assembled easily works great

This came out awesome. I had to do some minor cleanup as I didn't use supports.

doesnt fully close, very stiff.

@K4tana

Yes it doesn't, it is difficult to design one for 3d printing that does due to how layer height works, and you could see that in the gifs I posted. The stiffness is normal pla on pla isn't the most friction-free material with use it should lose up you can also add a bit of wd40 to improve on that,

prints well with PLA.

Prints OK, fiddly to put together, but the design seems a bit off - as if it was originally designed to be a part of something. No way to align it perfectly, it either does not close fully, or over-closes.

This is such a cool mechanism and lid for the container I made. My one critique is it’s quite stiff from the friction between the parts, don’t know if there just needs to be a bigger gap between parts or something else. Other than that it’s a fun print.

@K4tana

It depends on a lot of factors but using a bit of WD40 helps a lot with the friction give it a try :)
