10 // 1. You will want to git clone this repository.
12 // 2. Decide about the notification LED aperture. See the variable
13 // led_window_style, below. The default here is "ad-hoc
14 // multi-colour", which can produces a translucent (clear-ish)
15 // window set into the lid, even on a single-nozzle printer.
16 // See "Ad-hoc multi-colour", below.
18 // 3. use "make" to generate the necessary files:
20 // make -j8 fairphone-case.auto.scads `for f in \
26 // ; do echo fairphone-case,$f.auto.stl; done`
28 // 4. Print them. Case and OneKeeperPrint should probably be
31 // For Lid and LidWindowPrint, if you are doing ad-hoc
33 // i. Set up for clear filament
34 // ii. Print LidWindowPrint. Wait for it to finish.
35 // It won't take long. As soon as it finishes, tell
36 // your printer to warm up (so that in fact it does
38 // iii. Leaving the output so far on the printbed, reload
39 // your printer with the main lid colour.
40 // iv. Print LidPrint. You can let this go unattended.
42 // 5. Assemble the hinge. You will need 4x M2 12mm machine screws
43 // and 8x M2 full nuts.
45 // Make sure you get the hinge the right way round. If you're not
47 // openscad fairphone-case,DemoHinge.auto.scad
48 // to see an assembly diagram.
50 // The nuts recess into the hinge. You will want very fine
51 // pliers. As you screw each screw in, add the second nut when
52 // the screw thread emerges from the first - this will be a
53 // locknut. Screw each screw to an appropriate tightness for the
54 // hinge stiffness. You want the lid-side hinge to be stiffer as
55 // that makes closing the case work better.
57 // When you have the stiffness right, tighten the locknuts onto
62 // - To put the phone in, drop its RH side into the RH side of
63 // the case. Then feed the keeper through the small hole.
64 // Feed it right through.
66 // - The optional prop can be used to prop the phone up (in
67 // portrait orientation only right now). See
68 // openscad fairphone-case,DemoPropAngles.auto.scad
70 // Ad-hoc multi-colour
72 // This file is set up to let you make a translucent window using a
73 // single-extruder printer, using a "two print run" technique. This
74 // works well with our Lulzbot TAZ 5 and Aleph Objects' version of
75 // Cura. If you are using a different printer, you may need to
76 // adjust the parameters or try a different technique. In particular,
77 // initial_layer_thick
78 // set so that the window is one layer thick
79 // initial_layer_width
80 // set so that the slicer draws a rectangle around the whole
81 // object, rather than putting a "skirt" or anything inside
83 // If you have a dual-extruder printer, you can set led_window_style
84 // to 2 and do a single print of LidPrint and LidWindowPrint.
86 // Alternatively you can set it to 1 (just a hole) or 0 (no hole).
88 // Thanks to Clare Boothby for the ad-hoc multi-colour technique (and
89 // the parameters for our Lulzbot TAZ 5 and Aleph Objects's Cura).
93 // It might well be possible to adapt this file for other phones.
94 // If you do, let me know how you get on.
