There is NO WARRANTY. +// See below for full licensing and disclaimer. +// +// Instructions +// +// 1. You will want to git clone this repository. +// +// 2. Decide about the notification LED aperture. See the variable +// led_window_style, below. The default here is "ad-hoc +// multi-colour", which can produces a translucent (clear-ish) +// window set into the lid, even on a single-nozzle printer. +// See "Ad-hoc multi-colour", below. +// +// 3. use "make" to generate the necessary files: +// +// make -j8 fairphone-case.auto.scads `for f in \ +// HingePrint \ +// LidWindowPrint \ +// LidPrint \ +// OneKeeperPrint \ +// Case \ +// ; do echo fairphone-case,$f.auto.stl; done` +// +// 4. Print them. Case and OneKeeperPrint should probably be +// the same colour. +// +// For Lid and LidWindowPrint, if you are doing ad-hoc +// multi-colour: +// i. Set up for clear filament +// ii. Print LidWindowPrint. Wait for it to finish. +// It won't take long. As soon as it finishes, tell +// your printer to warm up (so that in fact it does +// not cool down). +// iii. Leaving the output so far on the printbed, reload +// your printer with the main lid colour. +// iv. Print LidPrint. You can let this go unattended. +// +// 5. Assemble the hinge. You will need 4x M2 12mm machine screws +// and 8x M2 full nuts. +// +// Make sure you get the hinge the right way round. If you're not +// sure, run +// openscad fairphone-case,DemoHinge.auto.scad +// to see an assembly diagram. +// +// The nuts recess into the hinge. You will want very fine +// pliers. As you screw each screw in, add the second nut when +// the screw thread emerges from the first - this will be a +// locknut. Screw each screw to an appropriate tightness for the +// hinge stiffness. You want the lid-side hinge to be stiffer as +// that makes closing the case work better. +// +// When you have the stiffness right, tighten the locknuts onto +// each first nut. +// +// 6. In use: +// +// - To put the phone in, drop its RH side into the RH side of +// the case. Then feed the keeper through the small hole. +// Feed it right through. +// +// - The optional prop can be used to prop the phone up (in +// portrait orientation only right now).
