I managed to get my hands a rather big 6in belt sander. It did not come with a vacuum attachment. I created one which seems to work.

The various parts are self explanatory. For my machine, i used the adapter which the extension and then used a base to attach it to the machine. I also added a few magnets to it so it does not move around.

I do not know how your sander looks, so i do not know if the base would work for you.

• I may make an additional part to which stops the saw dust from being blow from the adapter. I don't have any design idea for it but it is something i think it seems

• I think i used 5% zigzag infill for the base. To add strength, i used 3 outside walls instead the default 2. I maybe should have used more than 3 walls but it seems strong enough. I am using this in a workshop, so i want this to to tough, in case i drop it. For now, the 3 walls seems good enough

  • You should use infill of over 50% if not much higher. I used 5% because i did not expect my first try to actually fit.
• the diameter of the adapter is wrong, thus you are not able to connect your shop vac directly to it. You will need to use a shop vac connection joint, dont know the actual name, which is the same size on both sides.

• I need to create a part that strengthens the connection of the base and the adapter. I already have it drawn out on paper, just need to design it in Fushion 360

• I created a separate strengthening ring (will call it ring after this point) but made it a little to big. I need to reduce its size but have yet to do so.

• I will also create a base that comes combined with the ring but have yet to do so.

• I have added pictures of the ring when its installed. It does seem to make the overall design stronger.

• Before adding the ring, I attached the base and adaptor using CA glue. The connection failed. It could be due to the fact I may have used too little glue or more likely, i spray painted both parts which make the CA glue not work properly.

Anyway, once I printed the ring, I used hot glue gun and put down a lot of glue between and around the parts. Using this glue and the ring does seem to make a huge difference in overall strength

• I attached magnets to the bottom of my design using CA glue but most of them came off. Maybe using hot glue is a better method but have yet to try it. As a result, the whole assemble tips over with the weight of the shop vac when it is attached.

• I think adding the magnets that fell off should stop the tipping over, but have not tried. If it does not work, I have come up with another method to prevent it from tipping over.

• Magnets dont rly work. At least for my case, clamping it down instead is much better.

• Because i used 5% infill, my part snapped in half with the weight of the vacuum attached to it. I did not want to print another base with a higher infill. Instead i simply used hot glue to attach a piece of wood to make the base stronger

• I strongly suggest after you print this, to reinforce everything. I mean use some other stronger material to make this design stronger. I used PLA and I would imagine that if i put too much wieght on tip of this, it will break threw it. So I may add a small wood top to add to it.
