Sandie, the sanding pen

thingiverse

There's plenty of awesome sanding tools out there, but I'd had an idea brewing in my head so decided to give it a shot. The concept was to create a tool capable of tackling various situations - if you have a specific hard spot to sand, this should come in handy. Two versions: 5mm Sandie - 119x13mm "pen" with 5mm tips that use sanding paper strips up to 5mm width 10mm Sandie - 119x21mm "pen" with 10mm tips that use strips up to 10mm The length of the strips only needs to cover the entire tip; otherwise, it can be as long as you want. I've tested 300 to 3000 grit paper and it works fine on both. You can definitely use higher grit, but I wouldn't go lower than 300 on the 5mm Sandie - it should work just fine on the 10mm Sandie too. I provided a blank tip STEP file for both versions so you can make your own tips. Made a video to present it; it's honestly way longer than it needs to be and the part I used to sand isn't an accurate representation of a "hard spot" to sand. https://youtu.be/8pWhbxcNV0I No hardware is needed. Happy sanding! ______________________________________________________ Changelog: 03-06-2020 - Added lead-ins to the male threads, making it much easier to start screwing now. Thanks Chris C. for the suggestion! 19-05-2020 - Fixed the text on the pen parts; it should be readable even with higher layer heights (tested 0.12 to 0.32mm and it works well). Thanks Coizado for the feedback! 26-11-2019 - Re-uploaded the threaded STLs for compatibility with Slic3r; it was picking up separate model objects and not printing the threads. Should be working now. Thanks Microbzz for the feedback! 21-12-2019 - Uploaded "5mm - Pen Reinforced" for those who were unsuccessful with the original version; I doubled the thread wall thickness, making it much stronger. However, this makes sliding a sanding strip wider than 4mm much harder, if not impossible. Thanks Jweaver for the feedback!
