Description

PLEASE READ THE ASSEMBLY GUIDE

Here is a handy utility blade that is great for opening boxes and breaking them down.

I use these all the time.

This also makes a great gift.

Please see my detailed assembly guide for more details

Now there is a belt sheath to go with it if you like.

@COMRADE_ZACH

Oh no! Have you cleaned your build plate recently? You could also add additional brim in the slicer.

Print 3 looks excellent, but let it cool down properly Same filament manufacturer, same filament type: PETG, just a different spool I believe the turquoise filament is defective, the green one is perfectly fine

I too have had two failed prints. it seemed to fail in the same spot (roughly). I changed it from grid to gyroid infill. I am running #3 now. Let's hop, like you, the third time is the charm.

It came out pretty much perfect, besides filling a few spots! I wish it were easier to change the blade, though! Maybe figure out a different way to hold the blade in place?

The designer has replied

@COMRADE_ZACH

Yeah, the ease of blade changes was a trade off I made for a more secure blade engagement. I do have some ideas i started on, but I just haven't finished/tried them yet.

I love the knife I used it all day at work it feels super comfortable in hand and is very sturdy thank you for uploading this!

Replying to @COMRADE_ZACH :

one cool idea would be a pocket or belt holster for this its pretty bulky in your pocket

This was a beautiful design and print, thanks for sharing. I was too lazy to watch the youtube video so I just watched the GIF on here over and over but it worked.

1. It would be cool to see a version that doesn't need rubber bands like in the fidget knife: https://makerworld.com/en/models/449279 2. Also, a variant that supports the single edge rectangle blade since I already have a lot of those for other box cutters

The designer has replied

@COMRADE_ZACH

Love the feedback. I'm going to print the one you linked and cycle test it. I haven't had long life from plastic spings in the past, but maybe this design has it. I also like the idea of making a version work with the rectangular blades as well.

Replying to @COMRADE_ZACH :

update on this? anxiously waiting and excited

@COMRADE_ZACH

Replying to @3DTater :

I've made some progress, but I need the design to be as reliable as the current design. The latches are tricky because they need to have constant force and plastic relaxes and deforms under load over time. The main spring is good, but its only under tension/compression during actuation, just a short second.

@fabiograyci

Hello I saw that some prints have been having problems due to one of the parts falling I have a solution to present in fact I answered some comments Change the position by rotating 90º on the blue arrow corresponding to the Z axis so that the movement of the plate does not knock over the object Mine also failed the first time so I did this and it worked

Very well thought out design. The manual brims/supports included in the model worked perfectly and needed zero adjustments. The assembly guide with pictures was great too! Thanks!

@user_2558227435

Great little box knife. Added our companies logo on the side and it turned out awesome!

Looks great!
