Insect specimen holder_v10/ Insect manipulator_v10

This is the 10th version of the insect specimen holder me and my colleagues are working on.

It needs one of each part to work, they are already scaled and need a precise and calibrated printer so they do not break.

Settings:

Filament: PLA or PETG (I didn't test with others or infused filament, but they must work fine. PETG is preferable as it is more durable to friction than PLA)

Layer height: 0.2mm

Scarf sean: contour and hole

Scarf sean on internal walls: yes

Precise walls: yes

Precise Z height: yes

Wall generator: classic (Arachne sould work even better, but I must test it, still)

Wall print order: internal/external

Number of walls: 2

Infill on the taller round axis: 50%

Infill on every other part: 10%

Type of infill: gyroid (it is more durable during my tests)

Speed on small perimeters: 25%

The speed on turns (english is not my first language and I don't know how to translate this properlly, sorry) must be 75% of the standar amount on speedy printers. My settings on Orca Slicer on this matter are 35mm/s, 24mm/s and 15mm/s, in this order, from the second option to last (first one is 0mm/s for some reason).

Building instructions:

You will need to put the brick tower in the base, it is a tight fit, I put both on a plain surface and the weght of my body so they snap in place, the round protuding part must be facing the internal part of the base, the one with a round cutout.

Then you must put, carefully, the longer round axis through the brick tower. The arm sould be next, it is another tight fit, but easier than the last. The thicker part must be the one used for this part.

At last, you will put the smaller round axis through the other hole, in the thinner part of the arm, and snap the small basket on top. This part must not be tight, as it is intended to rotate the specimen quite easily and don't need friction to stop it mid air.

As a final toutch, you sould put modeling clay, a rubber, or another soft, squishy, material, so that the pin can go in easily, but still not fall upside down with your specimen on it (trully nightmare fuel).

FINAL TOUGHTS

It was a journey modifing model after model and printing prototype after prototype. Altought I am still not 100% satisfied with the final results and probably will post a model v_ad infinitum, I think this is a good starting point so others can have a go at it.

Happy printing!
