Sanding Blocks 125mm and 150mm Sanding Disks

prusaprinters

To complete my Mirka DEROS sander and don't have to take it out for small and quick jobs, I designed and 3D printed sanding blocks for the 125mm and 150mm sanding disks I useDesignDesign from Fusion 360 is quite simple. I started from the profile of the blocks and use “Revolution” featureFor the handle I reproduce more or less the one from my Mirka sanderThe diameter of the base is a little smaller than the pad one (-1mm). So when sanding corners there is no risk to damage the part with the block more the sanding pad will be easier to centerBoth 125mm and 150mm blocks use same profile. Just diameter of the bottom surface changes Printing instructionsPrinted in PLA Prusament Pineapple Yellow and Jet Black to look like Mirka colors (Yellow and Black)I used “Fuzzy Skin” feature from PursaSlicer on the black part to have more grip on the handleIt's sliced using PrusaSlicer using0,20mm layer height3 perimeters10% infill / GyroidColor change M600 (from Yellow to Black) at 30mm heightFuzzy Skin activated at 30mm height (Synchronized with color change)Printing time 6H48 for the 125mm and 8H13 for the 150mmIt can be printed faster with 0,25mm layer height. But the surface will be less smooth, mainly for the top of the handleYou can use “Variable layer height” option from PrusaSlicer, that I didn't used for this model MaterialBest way is to don't stick directly sanding disk to the block. Better to use interface, so sanding disk can be changed easily from the blocks1st option: Use protective pads like the ones used with the orbital sander. Stick it to the block using double side adhesive. Sanding disk can be easily changed. That's the one I used 2nd option: Use of self adhesive hook and loop tapes you can find easily from internet to attache directly sanding disks. Stick only the Hook on the block On top of .stl and .3mf files, I uploaded Fusion 360 .f3d file so you can modify the design and adapt it to your needsAs usual, feedback and comments (and for sure "likes") will be always welcome. Feel free to post nice pictures of your makesYou can also look at other Mirka DEROS accessories I designed and 3D printedMirka DEROS vacuum hose connector Mirka DEROS Orbital Sander Handler for SystainerEnjoy If you like this model, take a look also at my other designs
