Note: After 2 years of workhorse use, this Thing is no longer being supported or developed! Please try the updated and more feature complete version located here http://www.thingiverse.com/thing:66030This OpenSCAD script will generate a 2 part fit together packaging which connect together using simple lips. One of the objects will have an internal lip the other one will have an external lip. The ridges left by 3d printing provide grooves which acts as teeth to secure the 2 halves. It can also create simple square or cylindrical cutouts on any face of the top or bottom half 4 cylindrical support posts can also be added on the bottom or top half to help position a PCB or similar device You can specify fit and tolerances All these features can be turned on/off from the control variables sectionWith this script you can easily make packaging for almost any electronic device you are working on!This looks complicated but it has saved me a huge amount of time making custom packages for people over the past few days. The most recent versions (2012_05_29-Tyndall_Generic_Device_Packaging-v1.6.scad) have options for easily adding mouse ears, support posts, having cutouts not penetrate the outer face for better surface finish, generating only 1 side or both, incorporating other parts and models of internal electronics and showing the device assembled or as side by side parts!Changes from previous versions: v1.6Measure the device to be packaged. There can be quite a lot of dimensions to be recorded so be patient and write them down!Record the devices Maximum X, Y & Z dimensions, generally X and y will be the length and breadth of your PCB, while Z will be the sum of the height of the tallest component on each side of the PCB and the PCB thickness itself (these will become the values int_l, int_b & int_h respectively).Decide how thick you want the walls of your device to be, this will be entered into the variable "wall_t". I have printed these withe 2mm wall thickness but 3mm or 4mm give more consistent results.Record the shape and number of each cutout required for each "face" of the packaging as well as the size of each cutout and it's position relative to the centre of each face. In this script there are 6 faces (Top, Bottom, North, East , West & South). The meaning of "Size" depends on the type of cutout, if you want a rectangular cutout you need to specify its length & height, if you want a cylindrical cutout you need its radius, for a conical cutout you need internal and external radii (size_r_inner & size_r_outer). For example the version on this page has some of the following cutouts:Top Face - 1 conical cutout, @ pos_x = 3, pos_y = 3, with size_r_inner = 1, size_r_outer = 3West Face - 1 conical cutout, @ pos_x = 4, pos_y = 0.4, with size_x = 1, size_y = 3etc...If there are faces you don't need cutouts on simply comment out the line in the Relevant "Cutouts" section. If you need multiple holes on the one face the relevant line can be copied and pasted with different values for position and size.Open the OpenSCAD script In the "User Variables" Section In the "Clearance Type" Sub section Select the type of fit you would like by commenting/uncommenting the rlevant lines Specify how much extra space you want around your PCB using the clearance_pcb variableIn the "Internal Components Dimensions" Sub section Enter the length, breadth & height of the device to be packaged (int_l, int_b, int_h resepctively) Enter the radius of the corners of your PCB in the int_r variableIn the "Packaging Features" Sub Section Choose the number of facets on curved sides using variable curve_f (setting this to somewhere between 3 & 6 is good) Choose how thick in mm you want the walls of your packaging to be using variable wall_tIn the "Calls" Section In the "Top Half Square cutouts" Sub section Comment/uncomment/copy lines for each of the square cutouts required on the top half of your packaging Using the earlier recorded values enter values for pos_x, pos_y, size_x, size_y into the first 4 variables in each callIn the "Top Half Cylinder cutouts" Sub section Comment/uncomment/copy lines for each of the cylindrical or conical cutouts required on the top half of your packaging Using the earlier recorded values enter values for pos_x, pos_y, size_r_inner, size_r_outer (if you want a standard cylinder make size_r_inner & size_r_outer teh same value)In the "Bottom Half Square cutouts" Sub section Do similar procedure to "Top Half Square cutouts" Sub section In the "Bottom Half Cylidner cutouts" Sub section Do similar procedure to "Top Half cylinder cutouts" Sub sectionTake a breath! Phew Save (Press F2) Regenerate Shape (Press F6) Check it looks right (you can comment in the second "translate" command after "//Make top half of packaging" and "//Make bottom half of packaging" to see the 2 halves stacked on top of each other if this helps) Once it is correct looking export as STL Print Raftless Wait Receive Check fit of top and bottom half and clean out excess plastic if required Package your device Do a little monkey dance!
