elegant book stand

<div class="ThingPage__description--14TtH">
<p><span style="font-size: 16px;">An elegant collapsible book stand. It was designed with 3D-printing in mind, so there are (almost) no steep overhangs or bridges and no unnecessary filament consumption.<br>Make sure, that your printer is well calibrated, so that the two parts fit nicely together. Since version 1.2 the joint has a very tight fit, so it doesn't fall apart on its own. If you know your printer to over-extrude, lower your extrusion multiplier or use the "horizontal expansion" feature of your slicer with a value of about -0.02 to -0.05mm!</span></p><span style="font-size: 16px;">
<p>I tested this with books up to Din A4 (~8x11.5in). Prior to version 1.3 they toppled a little too easy, but that should be fixed now.</p>

<p><span style="font-size: 16px;">Since v1.2 there is a variant of the book stand that has two hidden magnet (disc 8x3mm) slots inside, so the two parts cohere while they are stored. To install them, you have to pause your print at the layer before the slot gets closed. For a print with 0.25mm layers that is <strong>layer height 4.75mm</strong>. You can do that manually or insert a M601 g-code at the right layer.<br>Then put a tiny drop of superglue in the slot and then the magnet. Doublecheck the polarity! Resume the print afterwars and you're done.</span></p>
