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!)

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.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.
