Star Generator for Laser Cutting 雷切星星產(chǎn)生器

This is a star generator designed with Fusion 360. I uploaded a 5-spike star as a sample (Those dxf files) which was designed for materials with 3.5 mm thickness. Still, feel free to download the f3d file and tweak it to fit your need.
Tweaking Tips
Most adjustable features were set as "User Paramete", which you can find from "MODIFY > Change Paramete". Functio of each Parameter were described in "Comments".
Making Tips
Export the last 4 Sketchs which has "ForCutting" in its name as DXF files. These are all you need for making a star.
Quantities of parts needed are based on the number of Spikes:
Template: 4 * # of Spikes
Each Holder: 2 * # of Spikes

If your material has an upper-side and a lower-side, flip half of the templates can keep all the outer-side the same sides.
Assembly Tips
Assembly could be tricky, especially the last piece. If "CuttingOffset" was set too high, the fitting will be so tight that the last piece might not be able to fit in.
It helps a lot using some fast-curing glue (eg. CA glue) to fix what you had already put together along your assembly.
PC_Holder and PB_Holder might looks similar, better keep an eye on who is who.
For most occasio, the template might looks like an isosceles triangle. It's a good idea to make sure the fit piece is well-oriented before glue it up.
Other Tips
The default design dig 1 slot for holder on each edge of the template. But as the star become bigger, 1 slot won't be enough for securing the connection. Thus, the f3d file with "2 Slots per Edge" is provided as well. However, as you might already noticed, this will double the holde and the difficulty of assembly.
這是一個用Fusion 360設(shè)計的雷切星星產(chǎn)生器。我附上了一個五芒星作為例子（那些dxf檔案，得用3.5mm厚的材料），但你可以直接下載f3d檔案來做修改，做出你希望的星星。
修改 Tips
大部分可調(diào)整的地方都設(shè)計成了「User Paramete」，你可以從「MODIFY > Change Paramete」找到設(shè)定頁面。每一個參數(shù)的功能都說明在「Comments」欄位中了。
製作 Tips
匯出名稱後頭有「ForCutting」的最後那4個草圖，這就是你所需要的DXF檔案。
所需的零件數(shù)量是根據(jù)星芒的數(shù)量變動的：
模板：4 * 星芒數(shù)量
每一個固定扣：2 * 星芒數(shù)量

如果你的材料有分正面和反面，在製作前先對一半的模板圖檔做翻轉(zhuǎn)，就可以讓最後的星星外側(cè)都保持是正面。
組合 Tips
組合可能會有點難，尤其是最後一片模板。如果「CuttingOffset」被設(shè)定得太大，組合會變得很緊，進而可能造成最後一片根本組不進去。
一邊組合的同時，一邊使用接合速度快的接著劑（例如快乾）把已經(jīng)組合的部分固定，會讓組合的過程變得容易許多。
PC_Holder和PB_Holder這兩個固定扣可能會長得很像，要記得分清楚。
大部分的時候，模板可能會長得很像等腰三角形。因此，再開始黏結(jié)第一片模板前，最好再三確認它的方向是正確的。
其他 Tips
預(yù)設(shè)的設(shè)計在模板的每一個邊都挖了一個固定扣的孔。但是當星星越來越大時，一個固定扣可能不足以固定模板的連結(jié)。因此，檔案中也提供了每邊挖兩個孔的f3d檔案（檔名有「2 Slots per Edge」那個）。不過，使用這個設(shè)計會使固定扣的數(shù)量加倍，也會讓組裝的難度加倍。
