<p>DIY Ball Sander for sanding concave items.</p> <p>This is for my Dremel<br/> I found a design i could work with and edited it with Tinkercad. ( I dont have the link of the original Design of the main shaft holder, if you think this is your design, let me know, I will add that information here )</p> <p>I used the sandpaper on ball template from <a href="http://www.davidreedsmith.com/articles/foamballsander/foamballsander.htm">http://www.davidreedsmith.com/articles/foamballsander/foamballsander.htm</a></p> <p>edited it in Paint.net to my liking<br/> uploaded it to selva3d.com to convert it to STL</p> <p>required<br/> Dremel<br/> 1x m3x20mm bolt<br/> 2x m3 nut<br/> KrazyGlue<br/> Velcro pads</p> <p>I printed this in PETG</p> <p>things to note:<br/> I could have made the hole for the bolt a bit bigger as it is quite a tight fit ( had to screw it through)<br/> I could have given the ball more depth (Z axis height)</p> <p>The flower is incorrect in size, will need to enlarge</p> <h3> Post-Printing</h3> <p><strong>sand paper template</strong></p> <p><div><p>use the flower like template to cut your sandpaper<br/> ( and velcro if you are going that route with an exacto knife for best fit onto the ball.</p> <p>you could either use cheap hot glue and glue directly onto the ball<br/> ( i say cheap because it is easier to peel off )</p> <p>or</p> <p>use velcro pads</p> </div></p> Category: Tools
