Description
It is recommended to use the latest enhanced version below, which provides better style and handling. |
Have a knife day! Branched from Over-engineered OTF into double-bladed version. Also good for brenchmark print. Lots of variants. Lots of patterns. Fully 3D printed. Upgradeable. Good as gift. Also very nice as comb.
(This is an over-engineered model. Please always print using a print profile and DO NOT try to slice it yourself!)
⚠️⚠️⚠️⚠️⚠️Make sure no ELEPHANT FOOT.⚠️⚠️⚠️⚠️⚠️‼️‼️‼️‼️‼️Especially if you print from A1 mini or A1. ‼️‼️‼️‼️‼️🌟🌟🌟🌟In Bambu Studio, increase default Elephant Foot Compensation to 0.15 [ Wiki link ]🌟🌟🌟🌟 |
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 set 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. Strongly suggest Liquid Glue in BambuStore.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 0:0:55 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 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.
Build instruction video.
Yet another OTF fidget, Anti-anxiety, ADHD.
More pattern and print profile to be updated.
Blade Type
btw. Thumb pain indicates that the OTF is not working properly. You're trying to cover all the print and filament error with your Hulk thumb. A good OTF can be triggered through your pinky finger!
Don't forget to try my Gravity Knife!
Also try this hourglass clock!
