Mechanical Slide

3D model description

Wanted to make a mechanical slide that didn’t cost hundreds of dollars! HA! Anyway, I think this is a pretty simple design; mainly made from 3D Printed Parts. Not the quality of an OEM Slide but works none the less. Other than some screws and nuts, has two main OEM items to purchase. One, 1/8” Brass U-Channel. It’s pretty cheap and you can get it at most any Hobby Store or online. Two, need 1/8” diameter steel balls. I got mine online but should be easy to get.

Other than that, this was easy to put together. Assemble the unit on its side; use posted pictures with assembly notes.

Things to note.

1. When building the parts pay attention to build direction. I needed no supports for any of the parts. Think it took about an hour and a half to print a set of parts on standard settings.

2. The Brass Channel isn’t perfect. I found one side of the U-Shape to be slightly higher than the other. I just made sure to keep this bias to one side of the bearings. If you machined your own U-Channel you could improve performance.

3. After assembly there is still some play (.005-.010). But, with a modest load (couple of pounds or less) this slide will give consistent use and good life. Interested to see if someone can give it some practical use.

4. I provided Bearing Cage files for 2, 3, 4, 5 balls so you can play with how many balls you want vs. application.

Note: some of the parts (blue) are not shown in the correct orientation. The Slide Base and Slide Body are shown upside down and the Slide Base Rail is shown on it's end. Should be on the long side so the long pocket faces up.
