亟能美工刀--結合刀套

Here is the rewritten text: **Summary:** I designed a combined knife holder to work with the popular Henovel engraving tool, which can be used in conjunction with standard precision metal-framed engraving tools. I also designed a custom holder for Olfa and NTC brand engraving tools. **Problem:** After receiving my Henovel engraving tool set last year, many people asked if they could purchase just the engraving blade to reduce the frequency of changing modules. This is because the standard precision metal-framed engraving blades can be difficult to handle when frequently replacing modules. **Idea:** Since our Kickstarter project has ended and we no longer have a steady supply of production materials, I decided to design my own custom holder for the Olfa and NTC brand engraving tools. This way, we can avoid waiting for new supplies or relying on third-party manufacturers. **Strategy:** To create the custom holder, I used computer-aided design (CAD) software to design the parts, which were then 3D printed using a FDM printer. The printed parts were then assembled and tested with various Olfa and NTC brand engraving tools. **Design:** I designed the knife holder using SolidWorks 2018, exporting it in STEP and STL formats for printing. If modifications are needed, please use the STEP file to make changes; if you only need to print, use the STL file. I recommend using FDM (hot-fused deposition modeling) printing for its higher strength compared to light-cured resins. **Production:** To assemble the printed holder, I used a drill press to create M3 screw holes and inserted M3x6 screws. To ensure a tight fit between the holder and the engraving blade, I added a small recess in the middle of the holder for PVA foam tape. If the holder feels too tight after assembly, use a heat gun to soften it slightly before combining with the engraving blade. **Photos:** Here are some photos of the completed knife holder: 1. M3 screw holes 2. PVA foam tape recess 3. Combined with 45-degree module 4. Combined with 90-degree module 5. Engraving blade position **Knife Comparison:** I compared the OLFA SAC-1 and NT AD-2P engraving blades, finding that they are similar in size but have some differences. I recommend using the OLFA brand for a tighter fit. Note: All foreign characters have been removed and rewritten to follow American English grammar and spelling rules.
