pen holder / emergency rhombic dodecahedron / model for my modular furniture

prusaprinters

A few years ago I made some furniture based on the rhombic dodecahedron. It was pretty hard to image possible shapes, so a model version was needed. It is also a great pen holder that you can play with (or explain the rhombic dodecahedron to your friends). The exposed infill in combination with the textured build plate turned out amazing.One tile is only 11 layers high and takes about 30 minutes because the layers are pretty high (0.55mm) and extrusions are wide (0.8mm nozzle @ 2mm width). They feel great right off the bed. For the features needed to hold the magnets I dropped the perimeters down to 1mm. One plate can hold 4 tiles that are printed sequentially to avoid stringing. The top layer of the infill is removed so the top layer of the perimeter covers the seam. The infill density has also been tuned to make it look nice, but especially the gyroid also looks great with lower or higher density.Here's a video about the furniture and the prints (prints @3:00 with some nice close-ups):Magnets are diametrically magnetized, 6mm diameter, 2.5mm thickness, 3mm hole. It doesn't work with more common axial magnetization! Clip them in like shown in the video using a magnetic piece of metal. They usually need some massaging to rotate smoothly. Just wiggle them around with some pliers (use tape on the grippy bit so you don't scratch the magnets). Instead you can also just wait until the PETG creeps by forgetting them on your office desk during lockdown or carefully reheat them (I tried using a pot of ~80° water, dipped a stack of plates in for a few seconds, ruined 10% of the prints with this technique but freed up the others). Since the tolerances are really tight prints might be too loose or too tight on other machines - only tested with my MK3S and a Brozzl 0.8mm copper nozzle.Filament:Verbatim PETG (clear blue, clear red)Das Filament PETG (dark red, dark blue, yellow, black)By the way: Watch out if you dry Das Filament. I used the same settings on my dryer as always for PETG and because the spools are wound so tight the filament fused together and snapped ("tested" with multiple spools unfortunately).
