sometimes I'll hit problems with puzzlecut where openscad kind of freaks out due to the amount of model data.issues seems to be that puzzlecut creates a new copy of the model for each cut - so openscad might be able to handle 1x of the model - but not 6x. nice work on pincut!
The example files worked fine, but when I try to do it on a more detailed model, it ends up looking strange. Half of a section will turn out looking ok, but parts of the section that's supposed to be gone will show up. The model I'm working with is:

just checked with the latest openscad - all works fine. I would start by trying one of the sample scripts.

One thing - puzzlecut effectively re-renders the entire object each time for each cut. So - it's possible OpenScad is having trouble dealing with that much data... if you can simplify your STL that might help.

have fun!

Instructions

This OpenSCAD library lets you easily cut objects into interlocking pieces for 3d printing or laser cutting.

Useful for printing objects larger than your printer can handle - or breaking a big job into smaller pieces - so failing doesn't suck as bad.

Place puzzle cuts anywhere you like along the X and/or Y axis.

If you want to change the location of the main cut lines - translate / rotate your object beforehand.

The size of the puzzle cuts can easily be adjusted. You can also adjust "kerf" for a tighter or looser fit.

See included puzzlecutdemo2 file for example of how to import an existing .STL.

Get OpenSCAD here: openscad.org

Demo object: "Bucket O' Octopodes (thicker legs)" - thingiverse.com/thing:8896

TIP: A kerf of -0.3 is a good starting point if your looking for snug fitting 3d printed parts (thanks toof!).

NOTE: Complex objects may result in "normalized tree" errors / rendering problems. These can be worked around by doing a full render (just hit F6).

UPDATES:

PuzzleCut now supports multiple cut lines per axis! See multicutdemo.scad for an example. This update also changes the cut location variable names (see demo files).

Updated puzzlecutdemo2.scad with some larger cuts and reasonable default kerf. Should now make a good test print without any changes.

Is there a specific openscad version required for the puzzlecut scripts? I don't know why my cut gear crashes when exporting to STL but it can process F5 and F6 correctly.. Where may I have gone wrong? Thanks -Sorry in advance if ever this is a noob question.. Thanks!! :)

This works great the only problem I am having is that it does not generate enough notches to hold the pieces together. For some of my stl's it is only making one. Is there any way to correct this?
You should be able to add as many cuts as needed by modifying the xcutlocation / ycutlocation arrays.

If you're not seeing the cuts - they are likely outside your STL - I'd keep playing with the values to see if you can get them to appear.

You also may need to use the translate command to reposition your model. If things aren't working - you might want to start by playing with the example a bit.

Hope this helps!

ok so i am new how do i center my stl file to cut it equal?
This is genius! Excellent for simply cutting up large models into printable chunks. Thanks.
A kerf value of -0.3 is an excellent place to start for 3d printed objects It makes a stiff joint that could be glued for a permanent join.
Cool idea! Keep them coming!
Would you be willing to share the octopus puzzle model?
I have a CNC machine and want to try to mill it up from solid mango or Ipe :D I've never heard of openscad before and am not sure how to use it correctly....
