This is a remix to the original. I decided to make smaller sized wedges for sanding as I build a lot of smaller parts and the larger wedge makes it a little more difficult to use.
Here are the changes......
You will need a M3 socket style bolt that is 25mm
You will need a M3 nut
Sand Paper with your choice of grits.I purchased two variety packs from Walmart from the automobile section which contains 80, 180, 400, 1500 and then 2nd package has 1000, 1500, 2000, 2500. These have worked well with 3D models I've printed.
NOTE: Inside the base (wedge) you will find a hole to insert M3 nut. You will need to use small needle nose pliers to press nut into place. I added some super glue to the inside of the nut hole using a toothpick and then inserted nut so it will stay in place.
The knob, I also screwed the bolt into the knob but left enough out to add super glue around the inside area where the socket head of the bolt/screw will rest. Then using a hex wrench I continued to screw the bolt into the knob so bolt will not free up after ongoing use.
Credit goes to the developer of the original sanding wedge, it's an awesome design. All I did was resize and modified it to ensure it fit and a few other modifications that I mentioned above by adding the nut and changing a few things. I printed mine with no supports on a CR-10s.
Hope your able to put these into use and enjoy.
