Custom Stamp with Exchangeable Text
Description
And again a simply, customizable OpenSCAD design. This time it's a two component stamp, a generic handle part and an interchangeable rubber part; no gluing necessary, simply print one or more texts and switch them around as you like. # Updates / News * **2018-12-04: v1.2** * Add new parameters `base_shape` for new round / oval base shape. * Removed specific rubber dimensions in favor of auto calculated size, as in a previous version (thickness, rim width etc.). * Add support for 3 line of text + different font sizes per line. * Added STLs of an oval shaped 60x40mm `Stamp 3`. * Added a simple "Heart" example (hearts instead of text) to the OpenSCAD code (not usable in Customizer) + STLs. * 2018-11-27: Added STLs of larger Version `Stamp 2`. # How does this work? With the Customizer you are able to create your own stamp, not only with a custom text but also in a different size with a different handle style. ## I like / don't care about the style and size, I only want a custom text In this case do the following: First choose which model (size) you want: * `Stamp 1` has a 50x26mm base (46x22 space for the text). Default Customizor settings (compatible to all `Stamp 1` models, no changes necessary). * DEFAULT. If you open the customizer and don't change any dimensions, your resulting rubber handle / rubber part with be compatible to all `Stamp 1` STLs. * `Stamp 2` has a 70x30mm base (66x26 space for the text). Customizor settings you need to change for compatible models: * `base_dimensions = [70,30,12]` * Optional (relevant for handle only, not for rubber): * `handle_diameter = 30` * `handle_height = 50` * `Stamp 3` has a 60x40mm oval base. Customizor settings you need to change for compatible models: * `base_shape = Round` * `base_dimensions = [60,40,12]` * Optional (relevant for handle only, not for rubber): * `handle_diameter = 30` * `handle_height = 50` * Download and print one of the `Stamp X Bazier Handle.stl` file for the handle. * Open the Customizer, select **`model = Rubber`** and change the following parameters: * `text_string` and `text_string2`: Enter the text you want. In case `text_string2` is empty, there will be one line of text, else 2. * `text_font_name`: Set the font name to one of [these](https://fonts.google.com/) * `text_font_style`: Optionally set a style (available styles depend on the font) like: "Bold", "Italic", "Bold Italic", "Black", etc. * Play with the other `text_` parameters, but don't touch the others, else you could end up with a part that doesn't fit into the `Stamp X` model. * _Exception 1:_ You want to increase the rubber base thickness, e.g. because you create a text without a border in which case its better to make the rubber thicker (if you want to be able to easy switch it). For this increase the z (3rd) value of the `rubber_dim` parameter. * _Exception 2:_ You want a slightly smaller rubber part (e.g. printer not perfectly tuned, print with non-flex material, etc.). In this case you can ever so slightly reduce the x and y (1st and 2nd) value of the `rubber_dim` parameter. * Create a new thing, download it and print it, preferably using some flex material (e.g. TPU). ## I want a different design and/or size * Open the Customizer, select **`model = Handle`**, set `base_dimensions`, set a fitting `rubber_dim` and play with the other parameters until you get the desired result. * Create a new thing, download it and print it. * Again open the Customizer, select **`model = Rubber`** and follow the steps from the previous section but make sure, that the parameters are the same as in the previous steps, so the size of the rubber part will fit the previously created handle. * Create a new thing, download it and print it, preferably using some flex material (e.g. TPU). ## General In any case print the handle with some sturdy material like PLA/PETG and the rubber with some flex material like TPU. When using the the default settings (no offsets) the rubber part should tightly fit into the handle. Since it's TPU you should be able to squeeze it in if your printer isn't calibrated perfectly, if it's still not fitting either consider ever so slightly reducing the x/y values of the `rubber_dim` parameter or, in case you print the handle too, tweak the offset parameter `rubber_cutout_offset`. ## Customizer Hints: * Always set the `resolution` parameter to `Draft` while tweaking (faster), but remember to set it to `Normal` before committing your changes. # STLs: There are currently 3 standard models, the smaller `Stamp 1`, and the larger `Stamp 2` rectangular shaped, and the oval shaped `Stamp 3`. ## Stamp 1 **`Stamp 1` has a 50x26mm base (46x22 space for the text).** All STLs models named `Stamp 1` are interchangeable. If you use the Customizor without changing any dimensional value, your resulting models will also be compatible. * **`Stamp 1 Bazier Handle.stl`:** A basic, Bézier curve based, stamp handle. * `Stamp 1 Straight Handle.stl`: An alternative handle based on straight geometric forms. * `Stamp 1 Stretched Handle.stl`: An alternative handle based on stretched spheres. * Some example rubber parts fitting the `Stamp 1` handles. * `Stamp 1 Rubber Blank.stl`: A template without any text. This could be imported into a 3D program to manually add some text, symbol(s), or whatever. * `Stamp 1 Rubber Blank with Border.stl`: Same as `Blank` but with a border. * `Stamp 1 Rubber Blank 4mm.stl`: Same as `Blank` but 4mm thick (vs. 2mm). * `Stamp 1 Rubber - Top Secret.stl`: Rubber with inscription "Top Secret" plus a border, font `DejaVu Serif:style=Bold` size 6. * `Stamp 1 Rubber - Love 4mm.stl`: Rubber with inscription "Love", font `Courgette` size 15. * `Stamp 1 Bazier Full - Top Secret.stl`: Full model, Bézier handle + "Top Secret" rubber (just a demo, not intended for printing). ## Stamp 2 **`Stamp 2` has a 70x30mm base (66x26 space for the text).** * **`Stamp 2 Bazier Handle.stl`:** A basic, Bézier curve based, stamp handle fitting all "Stamp 2" named rubber parts (STLs). * `Stamp 2 Rubber - Fragile.stl`: Rubber with inscription "FRAGILE" plus a border, font `Vollkorn:style=Black` size 10. * `Stamp 2 Rubber - Approved.stl`: Rubber with inscription "APPROVED" plus a border, font `Vollkorn:style=Black`. * `Stamp 2 Rubber - Rejected.stl`: Rubber with inscription "REJECTED" plus a border, font `Vollkorn:style=Black` size 8. * `Stamp 2 Rubber - Very Important.stl`: Rubber with inscription "VERY IMPORTANT" plus a border, font `Catamaran:style=Black` size 7. * `Stamp 2 Rubber Blank.stl`: A template without any text. * `Stamp 2 Rubber Blank with Border.stl`: Same as `Blank` but with a border. * `Stamp 2 Bazier Full - FRAGILE.stl`: Full model, Bézier handle + "FRAGILE" rubber (just a demo, not intended for printing). ## Stamp 3 **`Stamp 3` has a 60x40mm oval base.** * **`Stamp 3 Bazier Handle.stl`:** A basic, Bézier curve based, stamp handle fitting all "Stamp 3" named rubber parts (STLs). * `Stamp 3 Rubber - Top Secret Top.stl`: Rubber with 3 lined inscription "TOP SECRET TOP" plus a border, font `Vollkorn:style=Black` size 6 (top/bottom) and size 9.5 (center). * `Stamp 3 Rubber Blank.stl`: A template without any text. * `Stamp 3 Rubber Blank.stl`: A template without any text. * `Stamp 3 Rubber Heart Big.stl`: A non-text example showing a heart. The `Heart.svg` (2d) file was simply loaded into openscad and extruded like this: * `ranslate([0,0,rubber_base_thickness]) linear_extrude(text_thickness) scale([s,s,1]) import("Heart.svg");` _(where s is an optional scaling factor)_. * `Stamp 3 Rubber Hearts.stl`: Same as above. * `Stamp 3 Bazier Full - Top Secret Top.stl`: Full model, Bézier handle + "TOP SECRET TOP" rubber (just a demo, not intended for printing).
