„Trådförvarare“: Dry Box Spool Holder for IKEA Samla 45L

prusaprinters

IntroI came up with this dry box holder after using 22L Samla boxes for a while to store my filament. Here are the advantages of using a 45L Samla box instead:It fits up to 10 spools compared to the 8 spools in 2x22L boxes while requiring the same spaceFilament swaps are less of an hassle as the likelihood of having to open multiple boxes is at least halvedThe setup is cheaper, as 2x22L boxes are more expensive than 1x45LThe 45L box is perfect for PLA, I have between 40-50% humidity in my area. and with desiccant I can store it below 20% for 6+ months depending on how frequently I have to open the box. I still use 22L boxes for hygroscopic material like Nylon, TPU or PVA, but with a gasket. FeaturesThis design has been optimized to minimize waste of filamentOne frame piece is 30g which is possible as it is only there to position the rod holdersThe complete print is 215g, that is less than many 22L spool holders out thereThe rods have been tested with double the load (5 stacked spools instead of 2.5 per section) for multiple daysThe rod holders are designed to leverage the additional space in the upper part of the box, generating the required space to fit 10 Bambu spoolsOptimized for loose desiccant as you can more easily see the color-change. Use the clips to easily get the frame out in one piece, when it is time to dry the desiccantPrinting instructionsPrint each plate in the profile once (slice all plates feature comes in handy). Note that the design requires a print bed of 250x170mm or bigger. You could split the frames in the middle, though. The last plate contains connector clips and hygrometer holder, which are optional. Here are the key settings should you use another slicer than Bambu Studio:Print the frame with two perimeters/walls at 0.28mm layer height and 15% cubic infillPrint the rods with 4 perimeters at 0.28mm layer height and 25% cubic infill and reduce the speed, if you have a high-speed printer with stock nozzlePrint the hygrometer holder with 0.16mm layer height and 15% infill, it has been designed to print without supports, but there is a small overhang benefiting from the lower layer heightAssembly & InstructionsPut the 4 frames together as shown in the assembly view below or use the assembly view in your slicerPut the 4 rods together and install them onto the rod holders. Note that the angled side of the rod holders have to face the outside rod holdersOptional: Put the digital hygrometer into the holder and clip it on one of the long edges. The holder is for hygrometers with a 41mm diameter on the inside (not the top). I bought the hygrometer on AmazonOptional: Use the other two connectors to keep the 2x2 frames together. Only required, if you put loose desiccant into the box and want to more easily remove the holder in one piece without removing the hygrometer first
