This is my take on the popular “Sanding Detailer” in the image below.  I thought the price tag was a little excessive, and I didn't like how they were held by spring tension in the middle.  I made these threaded to maintain tension as you use the sander.  Because of this design, I was able to get rid of the side runners along the sanding edge allowing you to use the entire sanding surface. Unlike the commercially available detailers, these won't lose tension if you put pressure in the wrong spot while sanding.  The threaded design keeps tension on the belt the entire time unless you loosen it to remove the belt.  That said, you can still easily rotate the belt to get a new sanding surface by loosening the thumb screw, rotating the belt, and tightening it back again. 

 

Sander Info

These are made for 10mm x 330mm (3/8" x 13") sanding belts.  I put a couple hundred printer hours in the thread design to make sure these will work without having to run threads in and out over and over, and that they would work well with different types of filament. The print profiles are set for .16 layer height. The very small threads just can't handle the .2 standard layer height so it's best to keep that setting. The end cap, tension screw, and thumb screw are set to print with brim. Brim is necessary to ensure you have a successful print. 

 

Filament tested:

Bambu Lab -PLA matte - 4 colors

Bambu Lab -PLA basic - 3 colors

Bambu Lab -PLA metal - 1 color

Bambu Lab -PETG-HF  - 4 colors

 

Assembly:

     After removing all the supports take the end cap and slide it in and out of the back of the main body a couple times just to clear any residual supports. Thread the tension screw into the end cap, place the knurled thumb screw in the main body cutout, then slide the end cap in to the back of the main body. You're ready to go!
