I modelled this cat in Maya, based on my own cat.
It is designed to be easily printable, even with 0% fill and no external support.

For more info on modelling for 3d printing in Maya, please check out my site: http://zoltanb.co.uk/tips-and-tricks-on-preparing-complex-models-for-3d-printing/

Give it a go, it only takes ~12 minutes to print this kitty! (on an Ultimaker)

Let me know what you think,
all comments/criticism welcome...
as long as you don't call my cat fat! :)

lucycat-large.stl added for printing bigger, shinier and cuter cats!
Higher res, also the tail has been modified for better printing.


For translucent print use:

  • Perimeters: 1
  • Solid Layers: 0
  • Fill density: 0

it you use "Solid Layers: 0", it would make a perfect finger puppet, too! :)

For larger prints:
use lucycat-large.stl, it is smoothed and modified slightly.

  • Perimeters: 2
  • Solid Layers: 10
  • Fill density: 0

I'm in the process of printing two of these -- One with a height of about 90mm and the other at 85% of that. I mirror-flipped the smaller one in Simplify3d. I'm using Hatchbox wood PLA and will sand, stain, and varnish them, using a different stain color for each. I used 4 layers and 35% infill to give me a little more heft and a little more thickness to work with during the finishing. I used the fine setting for layer thickness to reduce the "stepping" on the rounded top of the head and also to reduce the amount of sanding I'll be doing. Printing time for the big cat was about 3:45 and the smaller one will be about 2:45 using a Hatchbox Alpha. These will be a gift to my mother.

I made this as my test print for my new printer. AMAZING!

Are you sure that's a cat. Looks like a Ring Tailed Lemur to me. LOL Just kidding. Printing one out for my co-worker. His daughter loves cats.

Post a pic of it Grasshogger, looking forward to see it! :)

Having some trouble printing the ears. They keep turning out looking like small beer cans instead of ears. Any setting suggestions for skeinforge?

I had the same look when I set the printing speed too high. Try overiding the speed to 40% in replicatorG when it reaches the top of the head.

Otherwise, try lowering the layer height, it should give you extra detail, the ears should come out better, too.

Let me know if it worked! :)

hi! you have a nice looking kitty (not fat at all) XD i printed one but now everyone wants me to print them a cat

one thing i'd like to ask...my cat has a vertical scar over its left eye and down (from where the bed lowers each layer), i noticed from the pictures here those cats have no scars...can that be moved to the back of the kitty or something like that? im using Cura RC4

Hi Vevcra,

The position of the "scar" (which runs along at the back of my cat) depends on your gcode generator and the config you are using.

I found that even the smallest change will move the scar, so you might be able to move it simply by scaling the cat up by a couple of percent.

Alternatively, try tweaking the layer height.
Let me know if it worked! :)

The scar forms because the layer changes at the same point every time. When I printed with 10% infill, the printer changed layers at a different point each time, so the 'scar' was spread out over the entire cat in little indentions that were hard to notice unless you inspected the cat closely. You could try with 1%, and that might work, no guarantees at that low of an infill though.

Cura has a relatively new "Joris the outer edge" feature for the Ultimaker. It's meant to increase the Z axis continuously, so that you don't get the scar. It might be worth giving it a try....

How did you get that texture with PLA?

I used translucent pla, used Slic3r for creating the gcode. Here are the settings I used:

filament_diameter = 2.94

fill_density = 0

first_layer_height_ratio = 1

first_layer_temperature = 180

infill_acceleration = 50

infill_every_layers = 1

infill_speed = 30

layer_height = 0.1

nozzle_diameter = 0.4

perimeter_acceleration = 25

perimeter_speed = 20

perimeters = 1

small_perimeter_speed = 10

solid_infill_speed = 30

solid_layers = 0

support_material = 0

support_material_tool = 0

temperature = 180

travel_speed = 90

Is there an stl for this?

Eek, forgot to attach it. Just added it, cheers!

Brill, thanks :) Looks like a fun one to print too.

Just saw your print! awesome! :)

They came out very cute :) The er ... 'battle-scarred' one on the right was at 0.3mm layer size and the prettier one on the left was at 0.2mm.

Thanks again for the model :)
