Description

Ultimate challenge OTF NANO keychain box opener x-acto.

 

Have a knife day!   Branched from Over-engineered OTF into mini version. Good for benchmark test. Also very nice as a gift!

Lots of patterns. Fully 3D printed. Upgradeable. 

(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!

Looking for the right Utility Blade Holder, Xacto, 9mm, 18mm, trapezoid? Check my model list. :P

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 1:06 in the video) and the latch lever will prevent it from returning. Now you can install the top cover.

(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.

 

Yet another OTF fidget, Anti-anxiety, ADHD. 

More pattern and print profile to be updated. 

 

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

Or using metal spring upgrade kit.

This looks like a beautifully designed set. As a suggestion, would you be able to create a version that accepts a standard utility blade? See image attached.

The amount of purge waste is a bit unnecessary. Would prefer the parts to be split into plates to reduce purge waste and save on time too.

Why? We don't need to split into plates. You can always unselect parts to print in studio or handy app.

That would mean it's just another step someone has to be aware of before hitting print otherwise there'll be a lot of purge waste. It would be a bit more organised and clearer to understand what exactly I'm printing if certain parts are split into plates. There are a lot of print profiles that don't make it clear what is what especially when all pictures are the same. A possible alternative is to simplify it to 3 profiles with one that has different handles + spring, one that has the main latch, and one that has different blade options. This will ensure low purge waste whilst having a clearer overview of what to be printed.

Consider something like this with print by object on, you can print the entire knife with blade in a little over one hour with 4 filament swaps. Faster and less waste than the way you are providing it to people.

cute little knife. not all filaments print accurate enough! keep that in mind if it doesn't work. I recommend just regular pla. that's worked the best in my experience.

Is it silk/metal pla and black basic pla?

Replying to @iczfirz :
it was silk rainbow, but as you see it's small so it wasnt able to use enough material to switch colors. and the blade is regular black yes. both off brand filament but works great. I just have to print a seperate spring because if I recall correctly it uses the same material for the spring as the body, and silk is too fragile for that.

I was skeptical at first but wow, some pretty cool engineering you put into this. no wiggle or anything. Works better than my real OTF knife made in China lol. This will be a great tool to have for opening packages or other various cutting activities. make sure you put the blades in the right way. I'm a dodo and was trying to put it in backwards wondering why it wouldn't fit :)

Are there any plans to make it so once the blade that is being used, goes dull, you can pop it off and use the next 2? Not sure if putting one little blade in at a time will work? Hate to throw away 3 blades because 1 is dull

Replying to @Texas3DPolymers :
For safety issue. Coz it need good contact point to secure the blade. Base on my test and development, 3 segments is the minimal. 1 segment will pop off easily.

Printed fine but having either blade or latch seems to be getting stuck. Any suggestions to get it smooth?
