(7/3/2019) Update to allow different magnet sizes. I needed to double up the magnets for my large impact wrench sockets.
This Thing is specifically designed for my Craftsman socket set so I'm only including a couple sample stl files. Instead I'm including my Fusion 360 projects so you can tailor them for your own sockets.
Fusion 360 instructions are at the bottom. If you aren't familiar with Fusion 360 ... why not!? :-) It's free to start-ups and hobbyists. And to use these project files you don't even have to do any modeling. Just plug in the dimensions of your sockets and export the stl file.
If you find this Thing is the Cat's Meow, consider buying me a coffee. Thanks in advance. https://www.buymeacoffee.com/3dDave
- Socket5, Socket6, Socket7: Fusion 360 projects for 5, 6, and 7 hole holders. Each projec t also has MagTest body for testing the magnet hole size.
- No supports
- I printed PETG .2 layer, 4 perimeters and 150% speed after the first layer. I used different colors to distinguish between metric and English sizing.
- The transition between the magnet holes and socket holes may look kind of ugly at first, but it'll work itself out.
- Stock parameters are tailored for 10x3mm magnets, but you can specify the magnet size of your choice. For my big impact sockets, I double up the magnets.
- Keep magnet poll orientation the same on a holder.
- If you want holders that connect like in the pictures, reverse the polls of the two holders.
Fusion 360 notes:
- H1-H7, hole size for your sockets
- HoleTolerance, H1-H7 holes are enlarged by this figure for an easy fit
- Height, The height of the socket hole
- MagDiameter, The diameter of your magnets. Print MagTest and adjust size for a snug fit
- MagHeight, The Height of the hole for the magnet. You want this dimension about .5mm larger than your magnet so the magnet is slightly recessed after insertion.
- 3D printing isn't precise and some magnet holes may end up too large. I CA glue troublesome magnets. That's better than trying to force a magnet into a hole that's too small.
- Enter the H1-H7 numbers in an order that doesn't cause the perimeter lines to cross the holes. If that happens, Fusion 360 will split the model into multiple parts. You can always do an Undo and start over if that happens.
- Fusion 360 will give you errors about the hole fillets. This is because the socket hole fillets cross into each other. You can ignore that error.
- If you need to extrude a new body, take note how I did the transition between the magnet hole and socket hole. W/o supports this transition bar is required. Otherwise the bridges are an arc and that's like trying to print into thin air. There is an attached picture to show what I'm talking about.
