Summary

Don't have a 3D printer? Order this thing directly from me trough my 3DHubs.com page!

This is a repaired version of Herman_Lundgren's Knife. Took the full knife, repaired the model, and sliced it so there are no open faces.

Print in the highest possible quality so the blade looks less layered. I printed mine in 0.1 mm and it is decent. the lower the better.

Instructions

  1. Print
  2. Paint
  3. Profit

Why is there a hollow space between the blade and the handle?
The blade is hardly attached. Really confused

Hey -

I am wondering, which file do I print to get the full knife (as pictured)? If it's two files, how do I put it together? Thanks a ton!

Nevermind. Looked at a comment below, said it's more decent-looking if you do the two halves. Thanks!

I printed the cut 2 file with a raft and it printed great, I took my time separating the pieces and everything looked nice after. I started to cut the first file (upside down one) and was running in to issues with how the raft was setup, it would print the first triangle fine, but then would start to print the raft for the blade and would get all funky. after about 3 retries and releveling the plate and cleaning it good, I adjusted the build settings to 15% from 10% and added supports along with the rafts and so far so good. Will upload a picture when both pieces are complete.

Too... big...

Should I scale it down?
I have a customer that is an avid CS:GO fan.

i dont think you are allowed to use it since its just the repaired version of an thing that has no comercial use allowed

idk if thats a good idea. it would take 2 times as long and have a higher chance of failing. if it were me i would just scale the files down

While printing the knife, some of the upper layers collapsed onto the hexagonal infills. Is 40% not enough infill?

Which slicer are you using? Try increasing top layer count to at least 5 or 6 depending on your layer height.

40% is wayy too much. normaly i print with 15% or 20% when it needs to be strong. do you have a hotend cooler which cools the plastic while printing? that helps much with air wires. normaly it should be fine after 3-4 layers

Comments deleted.

I downloaded this to paint, however the knife is slightly too big for my printer. Would it be possible to get the original file before it was formatted to a .stl? Or would you recommend shrinking the design?

Im new to 3d printing but can you use this model on any 3d printer?

It depends on the bed size, but you can scale it down using cura, but you must have a g-code printer to use cura.

I printed out one half and it seems too small for my hands, Did you size yours up any? Or is the knife the actual size like in the game.

i made a remix but instead of splitting it into 2 halves, i took the part in the middle out so you can print it with something like metal if you want, and print the handle with something else.

What are the dimensions ? thanks

What kind of glue did you use??

I used typical superglue. You could also use ABS juice if using ABS plastic.

ABS juice? like acetone them and stick them together?

Do I have to use supports and rafts? Or would it print just fine without them?

I printed without supports or raft. Print the 2 halves not whole body, it will not come out nice. You might need to use a brim to hold the 2 parts flat on the bed depending on what printer you are using.

Oh, okay. My school has the Makerbot Replicator 2 (expensive!) and I've been trying to print the whole stl (white filament) and it always messes up. So printing 2 halves and super-glueing is the way to go then? Thanks for the quick reply!

ABS or PLA? I use PLA on either heated bed with glue-stick on glass or with blue tape and it works great. I would say printing 2 halves is the only way you'll get anything good looking out of it.

Makerbot ir expensive shit.. Nothing much to it. You have to master it as much as my self-built reprap for 500$ ^^. Good luck, post pics if you print it ;).

My printer is too small for the knife. Is there a way I could cut it in more pieces so that it can fit?

You could try using http://www.thingiverse.com/thing:35834 or some of it's remixes. Haven't tried tho ;)

PuzzleCut OpenSCAD Library

Could you upload the cut2, but mirror flipped? I tried printing the cut 1 but the supports were everywhere and it looks horrendous. I was hoping we I cut print one just like cut2 but flipped so I can glue the two together.

Thanks!

What program are you using for your 3D printer? You should be able to rotate the part 180 by X axis.

Just out of curiosity, what exactly did you fix of the original model?

Both model halves had open faces (the flat one facing down) and it did not want to properly slice (atleast on Slic3r). Running trough netfabb did not help so I had to properly slice the original model to fix the problem.

And also, are the holes for the finger on the half-models closed, or does it just look like that?

They indeed are "closed" with zero thickness walls so it should not affect the slicing (as it will be ignored).

Thanks for your answers man!
I will try to print it this weekend on my Replicator 2... We will see how it will turn out... (BTW will use MakerWare)
And a BIG THANKS for the Awesome model or to be precise for fixing it : )

Awesome model, well done!

Credits goes to Herman_Lundren ;) It's really an awesome model though :P

Was the one in the image printed as 1 piece or 2? Printed out the 2 halves and the blades fell off getting them off the build platform, was able to salvage it but it looks nowhere near as nice as the one you have.

try printing with a raft, the makerbot platform is great for one thing, holding onto the model with a deathgrip, so when its time to remove, its rediculously hard. If you print with a raft it makes the damage removing it done to the raft not the actual part. When exporting as x3g look for the option near the support and choose raft.

I made it from 2 halves using PLA and superglue. What do you mean, blade fell off? What printer/slicer are you using?

Makerbot Desktop 5th gen, was printed in .2 layer height. When we removed the 2 halves from the build plate the blades were barely hanging onto the rest of the model, one fell off, the other kinda flopped around.

I had the same thing happen. Did you solve this?
