Description

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

Have this knife in your tool box!    Branched from Over-engineered OTF into utility blade version.

Print profile default for Trapezoid .  18mm holder kit as a separate profile.

Or just print the dummy profile if you are not using it for utility blade.

Lots of patterns. Fully 3D printed except steel 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 After boosted, message me to get the handle with cutout windows!

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.

Lubricate thoroughly with cooking oil.

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 1:06 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.

This one shares the same Build video link of the full-size version.

Or using optional metal spring upgrade kit .

Print profiles and steps

Print this first. Dummy if without Trapezoid

Slim Pattern A. Suggest PETG & Less wrapping filament It will not function without the trapezoidal blade installed. If you don't have a trapezoidal blade, print a dummy blade . You can find it in the Print Profiles list.

!!!!!! Filaments with less warping must be used !!!!!!

Build video link .

Power-up kit. Half retracted for aggressive cutting

18mm Utility Blade Kit (Last 2+1 segment ONLY) Very common 18mm utility blade. Accept the last 2+1 segments ONLY. Please let me know if you have different spec.

The best way to insert the locking bolt is :

- put the bolt on table - align the blade to the holder - Press the holder to the bolt on the table Do not try to press the bolt with thumb. It's really hurt!

Two more slots at the end of the holder to store the extra two bolts.

Spring Kit. Multiple specifications in one set. Read desc. Don't get too excited after trying this.

Less coils counts = More force = Short lifespan, vice versa.

Please report back with the filament brand/type/color and whether it works for you.

Standard Inflate Pattern J. Use PETG and less warp filament. It will not function without the trapezoidal blade installed. If you don't have a trapezoidal blade, print a dummy blade . You can find it in the Print Profiles list.
