Cali Cat is designed to be the purrfect initial calibration and benchmarking print. It is a simple, standard test to ensure you have the basics down before proceeding to advanced prints. Cali Cat is the alternative to boring calibration cubes. It's a test print you can enjoy keeping. It consists of linear dimensioning tests of a calibration cube and more:

Linear dimensioning: Body 20x20mm, Height: 35mm, Tail 5x5mm
Inclines and overhangs: 45º
Debossing and Embossing of facial feature details

Prints in under 1 hour.
Calibrate your printer and grow an army of cats in the process!

Cats sit perfectly on another cat's head of 2x the size.

Is there a dog version of this? I'm allergic to cats.

I thought Benchy was the standard test print. :)

This is awesome!
Decided to have this one as my very first print ever only Tevo Tarantula. How satisfying to see a cat grow on your freshly self-assembled printer!
Very good testing object too. My spider has difficulties with 45 degree overhangs, apparently. Those tails look rediculous

Congrats on the 3d printer. Getting nice overhangs has a lot to do with a mixture of speed and having good cooling. You want the previous layer to be cool enough so it maintains its position so the next layer has a rigid structure to lay on top. You'll have an wonderful time once everything is dialed in.

I know, the Tarantula does not come with part cooling out-of-the box. So I ordered a fan already, and will print a duct for part cooling soon.
This will take some time to arrive, though. But really happy with the results so far. Nice, smooth straight walls, and the dimensions are within 0.05mm now, after two iterations of X-, and Y-steps corrections. So, once the fan is installed, I'll start playing with temps and speeds, and eventually with different materials.
I just love this tinkering! (As long as it leads to results in the end)

But, what I wanted to say, but was somehow cut off of my original post: Thanks for the design! Far nicer than the boring cube, and better suited to test the functionality of the printer, and T and V settings :)

hmmm Riddle me this....

Every facet of the cat comes out perfect - except for the back right hand corner at the top of the head. Small hole there (insufficient infill?) but the rest of the head is absolutely perfect.

Seems to be on the penultimate diagonal infill, but buggered if I know what's causing it. It's not bed placement, literally printed two cats side-by-side and they had identical holes. Not filament - seeing it universally across fil types. grrr...

can you upload pictures

literally just printed off another one - stepped the speed down a bit to see if I was having issues on that front, exact same symptoms.

Black cat is using 3dFillies PLA+ running at 200% (I usually print these off so my husband has some desk toys). White is Filaform at 100% for the base, down to 80% speed for the face and top of head. Temp 210, 100% flow 0.6 thickness and 10 fill density. Using a Cocoon Create mini (wanhao mini) with a stock nozzle. (yes these are currently uncalibrated for print perfection, but they show the problem quite nicely)

How many top layers are you using? You can try rotating it 90° on the Z axis and see what happens.

Very nice model! Thanks for sharing!

I've sliced it in S3D and printed it twice with different filament. Both prints have the same look - uneven edges, visible layers and distorsions - all the same on both cats. So I guess it's more a problem of the gcode than a problem of the printer. Right?

G-code is just giving your printer directions and commands. It's more likely you need to adjust your printer settings (within the slicer) or minor mechanical things such as tightening belts. Also, it's not odd that different filaments brands and even just different color would need different adjustments. S3D also has a nice visual guide on what you may try to tweak depending on the results of your prints: https://www.simplify3d.com/support/print-quality-troubleshooting/

ok i got my dimensions down to 0.1 mm or lower(my digital caliper and my hand is the problem to actually verify)
but the tail of this cat is off cause of warping and a little bit of blopping what should i do to reduce this? print slower?

Hard to say. Sounds like a cooling issue. Might even give it a go by dropping the hotend a couple degrees cooler.

Could you make this into a keychain.

Might be cool to put a tiny chain around its neck like a collar and connect your chain to that.

I think any jewelry section at any crafting store, Jo-ann, Michaels, etc would be able to help you out.

Cat KeyChain Calibration

Looks like someone remixed it with the just its head. You are absolutely free to make any remix of it as well.

Is this the answer to the 3d Benchy?

More of an alternative to a calibration cube. Much more simple and to see the very basic aberations on your prints before moving onto something a little more complex. And for cat reasons.

What...no calibration dog?

Maybe a dog in the near future

Love this little critter! Any suggestions on what setting I need to tweak if the angled section of the tail never prints quite right? Everything else prints wonderfully.

For PLA, a lot of times it's the need for proper active cooling of the layer properly sets so the next layer lays down properly and level.

Hard to say without seeing the print. Maybe post a picture of the print. 45 degree overhang is a doable standard which usually means the printer needs a little bit of calibration. Without seeing the print I'd probably guess the most common problem is the layers hasn't cooled enough so the proceeding layer doesn't lay on top properly. Combination of things to try turn up the fan speed to cool the part, slow down the print speed, and/or adjust the temperature of the hot end.

I have a MP Select Plus (Wanhao i3 clone) and I use Cura to slice. Printing in ABS, here's the settings: https://goo.gl/photos/XVC6GP3GTE66LNws6
Thanks for the help!

I don't personally have experience with the MP Select Plus. Perhaps there's an official/unofficial forum for your printer. ABS in general takes a bit more finessing than PLA. The one on the far left is definitely better. Note the changes every time you start a new calibration print and see if you're headed in the right direction and adjust accordingly. With ABS you can give it a try by printing with cooling fan totally off and see what happens. ABS also seems to print better with an enclosed printer. So maybe also try a makeshift tub over the entire printer or cardboard box surrounding it. I've also seen that many Monoprice printer owners make improvement parts on their printers, such as improved fan ducts that cool the part better than doesn't blow at the hot end as much. Again hopefully there's a forum for your specific printer and continue to play with different variables.

You must call it "Cat Libration"...

Made one today as my first print on Kossel XL. PLA with no warm bed. It worked well, the cat I made is 20.4 mm large. Unfortunately, my son stole it. This cat is definitly too cute!


Cat puns :)

Picking up errors with the model here:

[14:56:13] This should never happen, there is a hole in the triangle mesh, each edge should have two faces.
[14:56:13] 2561 [1608] [63, 867]
[14:56:13] Something will still be printed, but there is no guarantee that it will be the correct shape.
[14:56:13] Once the gcode is saved, you should check over the layer with a z of:
[14:56:13] 20.7749954584
[14:56:13] This should never happen, there is a hole in the triangle mesh, each edge should have two faces.
[14:56:13] 67 [33] [34, 35]

Had a couple naked edges and fixed the model. Thanks for spotting it. Let me know if you come into any more errors.

Going to pick up my filament then this will be my first print!
