I made this large sanding drums for Dremel, to myself, kinda in the rush. The label is crushed by the washer, but still readable. The flat bottom part was printed in PLA without support, but survived. I modeled this for my personal use, but decided to share, so don't expect any updates. They work well, for me, as is.
For each drum you will need:
1 M3 bold about 50mm long
2 M3 washers
1 M3 nut (i used self locking nuts because it was i had available but i recommend)
The slit is kinda useless. I just super glued some ordinary sandpaper around the body. The label was highlighted with some correction pen.
The author marked this model as their own original creation.
