Cup holder for IKEA MALM Bed frame

prusaprinters

<p>Coffee in bed is amazing. There’s no better way to wake up.</p> <p>I made a simple flat platform to hold a coffee cup onto a bed frame, specifically the <a href="https://www.ikea.com/us/en/catalog/products/S39931162/">MALM</a> from IKEA. The design is quite simple, so every part should be easily adapted or extended to other applications.</p> <p>PrusaPrinters does not currently allow the uploading of f3d files. You can grab the Fusion360 “source” file from <a href="https://www.thingiverse.com/thing:3653703/files">thingaverse</a></p> <p>Please keep in mind that I have no formal training on Fusion. constructive feedback is welcome!</p> <p>See the photos for the suggested print orientation and assembly.</p> <h3>Future work:</h3> <p>The steep angle on the head of the dovetail joint is not trivial to print. Even with adequate support material and ideal printing conditions, I still had a bit of warping. Not enough to be out-of-spec, but there’s probably a smarter way to integrate the groves of the joint into the body and make the tongue a separate part that’s easier to print.</p> <p>The plate is meant to be relatively easy to remove from the legs, but there’s probably a clever way to build in a simple retention mechanism that will keep the legs attached to the plate without relying on a friction fit that is difficult to undo.</p> <h3>Print instructions</h3><p>I have included the <code>stl</code> and <code>3mf</code> files.</p> <p>All parts are quite simple and have no intricate shapes or über-tight tolerances/clearances. The dovetail slot/tongue require a reasonably accurate/precise printer, but not overly so; I designed in quite a bit of clearance between the two as a <em>perfect</em> friction fit is not desirable.</p> <p>Infill is up to you, but I’d suggest 10-15% for the “legs” and 20% or more for the “plate” depending on your material choice. PLA is plenty for supporting a warm coffee mug.</p> <p>I printed with many perimeters for the legs and several top and bottom layers for the plate. This was probably overkill. You should probably just use the <code>stl</code> files with your slicer of choice, but my exact print settings are included in the <code>3mf</code> files.</p> <p>I have also included the Fusion360 “source” file as well. Please keep in mind that I have no formal training on Fusion. Designing this part was mostly for practice using a more <a href="https://www.youtube.com/watch?v=c51Qz0n--Lc">disciplined layout approach in Fusion360</a> and some experience designing <a href="https://en.wikipedia.org/wiki/Dovetail_joint#Through_dovetail">dovetail joints</a> into a printed part. <strong>constructive</strong> <em>feedback</em> is welcome!</p> <p>See the photos for the suggested print orientation and assembly. Note that I have enabled support material <strong>everywhere</strong> and <em>not</em> just on the build plate. This was needed for the steep angles on the tongue of the dovetail.</p> <p>All together, there will be about 7 hours of print time for the three parts, when using the <code>.2mm SPEED</code> setting in <a href="https://github.com/prusa3d/PrusaSlicer/releases">PrusaSlicer</a> on my MK3s.</p>
