Description

Check my crowdfunding project OE OTF RE: Redefine and Evolve

 

It is recommended to use the latest enhanced version below, which provides better style and handling.

Boost Me (for free)

Let's interact! Boost me, then DM me to get the handle with cutout windows! 

 

 

Have this knife in your tool box!   Branched from Over-engineered OTF into PRO Utility Blade version. 

 

The print profile is default for extracted 4 segment of 9mm snap blades.

Separate print profile of 2 segment extracted of 9mm snap blade parts and X-Acto(original or generic)

 

Fully 3D printed except 9mm snapoff utility blade. Upgradeable, such as metal spring upgrade kit.

(This is a over-engineered model. Please always print using a print profile and DO NOT try to slice it yourself!)

Boost Me (for free)

After boosted, message me to get the handle with cutout windows!

 

Here you go some variants  Pro Utility Blade Holder, Xacto, 9mm Mini Pro, 9mm Nano, 18mm, trapezoid. Or check my model list. :P

OTF Original

OTF Pro 18mm snap-off blade or Trapezoid.

OTF 18mm snap-off blade or Trapezoid.

 

OTF NANO 9mm snap-off blade or x-acto no11.

 

 

EDC KUT version

 

This accurate model requires printing using the most reliable filament and printer settings. Good as a benchmark testing your machine and filament setup. If you are confident in your settings, you may want to try changing the filament. But you can also try the spring kit profile. This will, to some extent, force the overturning of certain errors. Please let me know the results. Good luck.

 

The main problem is warping: The front cut out becomes smaller. The blade failed to catch the spring for ejection. 

Filament issues: The push lever is difficult to move(a common problem with silky), or if the parts need to sanded, this means you need to try a different filament colors/types. 

Installation issues:  The latch lever is oriented in a "V" shape, not an "A" shape. Pull the blade all the way out (reference time 01:03 in the video) and the latch lever will prevent it from returning. Now you can install the top cover.

Trapezoid based on these brands (Stanley/Hart/DeWALT/Husky/Toughbuilt). Some brands need the smaller dowel blade holder (different print profile)

(Don't blame a model or print profile by giving a low rating. It won't help you to be successful with your next print at all!)

 

Based on the review feedback, you'll definitely want to print more than one to show off. So consider using monochrome printing and then mixing the parts. Save both times and materials.

****No hardware required.  But if you want to use metal spring, here you go the upgrade kit using BA001, BA002

****Based on my experience, not all PLA filaments are suitable for precision printing.

**** Profile well testing using PETG-HF and PLA Basic, Sparkle and Marble. Strongly suggest PETG-HF, especially for the spring. And the PLA Silk Dual Color is not good for this precision print.
****If mixing filament types (e.g. PETG with PLA) for multiple colors, it is best to disable flow calibration.

 

 

More pattern and print profile to be updated. 

 

Build video link

You can check the original Build video link of the original OTF version.

Or using optional metal spring upgrade kit.

Petg should last long at least with my bambu petg hf. What is the brand and color you used for the spring? You may try the spring kit print profile. Or switch to metal spring kit option.

Replying to @iczfirz :
I'm using hatchbox black petg. Does the spring only go in one way? I noticed it looked a little cock-eyed when I put it in the first time, not sure if that matters. I tried different layer heights too in hopes of more walls but it doesn't seem to make a difference since it's so small.

Replying to @Texas3DPolymers :
Yes, in this 9mm Pro mini, the spring operates one way. You can see it in the build video. I know no idea about hatchbox PETG. From the video, almost all the demos OTF were made of bambulab petg hf except for one which was a metal spring. Have you tried the spring kit profile?

Thank you for making this version. It printed well but was difficult to get the blade pinned into place. It was not as straight-forward as the larger version. Thanks again.

Please bear with the dowel pin size as too loose will fail to secure the blade.

I printed a bunch of the Mini 9mm knives and they were awesome. This one is top notch too. I like this one better! It has noticeably more oomph to it when it goes in and out which makes it feel more solid. I guess this may be due to the metal blades + spring? great work and keep it up!

This is the version I did not realize I wanted. Printed just to use-up some filament ends which explains the colors. Thank you for the model.
