The ULTIMATE Magnetic Swappable Miniature Painting System!

This is a remix of a great set of handles, adding a clamp to hold models as well as a swappable cap system for painting your armies en-masse. The spring and magnet mechanisms are strong enough to even hold metal minis, like the marine pictured above!

The clamp holds any model from 24mm to 40mm. The compressed length of the spring will determine how wide it goes. If there are requests, I can make larger ones. 

You'll need:

• Two M3x20mm screws
• Two pen springs - ¾" to 1" long will do, preferrably matching.
• At least five magnets 6mm diameter, 3mm thick.
• One M3 10mm grub or button-head screw
• Optional: ¼" metal washers

Hot-swapping is possible by magnets. Two go into the handle, two for the clamp, and a single magnet for each cap. Just make sure you insert each pair consistently with the same pole orientation. They are pressure-fit but depending on tolerances you may want to print a test first in case you need to increase the hole size. 

The handle is fitted with a pivot point, either a grub screw leaving 3mm protruding, or a 10mm screw with the head cut off. 

Or, you could carve a cylinder from underneath, through the centre of the handle up to 7mm from the top to screw it in intact. This may leave the neck with only a couple of perimeters to stay attached, though. 

The insert can be printed in TPU/TPE and glued in for extra grip. Otherwise, the edges of the one-piece head are beveled for grip when printing in PLA or PETG.

There are two caps:

One uses a single magnet, and will keep fixed in two positions around the head. 

The second has an embedded ¼" washer (7.5mm ID, 19.5mm OD, 1.4 - 1.6mm thick) where you stop the print to insert the washer and continue the print. This allows you to swivel the cap freely. 

I've printed the handles with fuzzy skin at very low settings for a bit of textured grip, and set the bottom 12mm to a higher infill to give the bottom some weight. My printed handles are 22g.

The clamps should be printed on their outer edge. I've also added fuzzy skin to the sides of the clamp for better grip.

Note: You may see a notch on the caps or the base in the pictures. I originally intended to have a notch for all the parts to prevent them from rotating, but it turned out that the magnets alone strong enough.
