STORY

This make started with the intention of creating a compass to cut out my own circles for rotary sanding. The result ended up in coming up with a stylized handle design for x-acto 8mm #11 blades or similar. The blade holder has been threaded properly to be a working, usable design for your blades. I recommend reading instructions thoroughly as some of the information may prevent breakage and sharp metal shrapnel flying around your shop.

PRINTING INSTRUCTIONS

I recommend the use of stronger filament types such as ABS or PETG since this is not something you want to have snap on you and go flying...unless you like the idea of sharp blades flying around the room. For maximum strength, I recommend printing horizontally with or without supports depending on your printer and profile's ability to bridge. To print with less filament and without supports, printing vertically should work also, however keep in mind that because the layers will be width-oriented and not vertically oriented, it may affect the strength and increase the likelihood of it snapping in half under heavy load. I used 50%+ infill in a trihexagonal format generated by Cura when slicing for print. I am not a wizard when it comes to perfect infill ratios and distribution, so do whatever you are comfortable with or do some research on the best options if you are concerned about reliability/strength. This is what works for me, but to each their own. I used a custom profile that is optimized for very high resolution (0.1mm or less) and pushes the limits of the stock 0.4mm nozzles that come with most printers. This increases the print time considerably, but results in stronger prints with much better quality and detail. I have included the entire thing on the spiralknife-wblade.stl for the sake of viewing as it is intended to look after printing separately and assembling for use. This file is not intended to be printed. Ensure you load the three separate files: bladeholderV2.stl, swirlhandle.stl, and swirlbody.stl and print together or individually with the orientation as preferred.

DEVELOPMENT

As this is the first version of the item, if there is interest in tweaking, adjusting, or repairing any issues with this design or if you are interested and have ideas on other items similar to this that you would like to request, feel free to reach out in the comments and I will be happy to discuss, answer questions, and explore ideas with anyone that wishes to comment.

I also recognize there are no pictures or makes up yet, but that will change within a week. I have just fleshed this out and wanted to get it up right away as this is my first model uploaded and I am still figuring out how to use Thingiview and comparable softwares that help me accurately portray the contents of the files. I will have a printed and working make listed and up by the 4th of July, 2020./p>
