Magnet Dispenser for 3D Prints: Simplify Magnet Insertion with Precision

The Magnet Dispenser Tool is expertly designed to streamline the insertion of magnets into 3D prints. This tool not only speeds the process of inserting magnets into 3D Prints, it also ensures correct orientation and secure fitting, making it ideal for projects that require precise magnet placement.

Key Features

Dual Dispensers for Perfect Alignment

• Includes two dispensers for each magnet size – one for north-up and one for south-up orientations
• Use different colors (e.g., red for north-up and blue for south-up) to help easily identify the dispenser's orientation
• Eliminates the hassle of misaligned magnets

Design and Utility

• Developed after extensive refinement
• Allows for friction-fit insertion and is also suitable for magnets that are glued
• Tapered tip for use in tight spaces

Ease of Use

• The dispensers are designed to accommodate the specified magnet sizes for their internal holding magnets, but can dispense magnets of any thicknesses for the specified diameter. For example, for the 6x3mm dispenser, you will need 6x3mm magnets to assemble the dispenser, but once assembled, that dispenser can dispense any 6mm diameter magnet such as 6x1, 6x2, 6x3, 6x5, etc.

Convenience and Storage

• Features a snap-on cap with an embedded magnet and a top slider magnet to keep the magnet stack from sliding out when not in use
• Ensures secure storage and prevents accidental magnet spillage

Customization and Printability

• No supports needed for printing
• STL and STEP files included for personal customization
• Compatible with PETG, PLA, ASA, ABS, etc
• Adjust x/y hole compensation if needed for perfect fit

Visual Guide

• Fusion 360 images provided for easy assembly and understanding of the internal mechanism

NOTE 1: The 1mm magnet thickesses are just too thin to work reliably with the friction-fit of the slider and caps. Therefore, I have made the pockets of the “1mm” thickness magnet dispensers to be that of the 3mm variety so that they work. So to assemble a 1mm magnet thickness dispenser, you will need to purchase a few 3mm thick magnets to assemble the dispenser. A 2mm thickness will likely work ok, too. Note that the text on the dispenser will still say “D x 1 mm” for the barrel, “Dx1” on the cap, and “D/1” on the slider, so you know what magnets you have loaded into it.

NOTE 2: the above are the sizes needed to assemble the dispenser. The dispenser can still dispense any thickness of magnet as long as the diameter is the same. So if don't see your specific magnet thickness listed above, you can still print the correct diameter, assemble the dispenser with the correct magnet thickness, and dispense other thicknesses.

STEP and STL raw files are included if you do not wish to use the provided profile.

Testing

• I have printed all dispenser sizes and tested each extensively
• I have acquired and tested all magnet sizes to ensure fit, i.e., I did not simply use published thicknesses and diameters as they are often not accurate according to caliper measurements
• Magnet diameters are tricky for press-fit tolerance and controlled by several Fusion 360 parameters in the model that must be balanced to achieve a good fit for the magnet pockets (e.g., with a single parameter, if the diameter is right for the top of slider, it is usually wrong for the cap and bottom of the slider, etc - I believe this is due to how close or far away the pocket is to the heat-bed)
  • As a result, I've done my best to ensure the best quality printing and fit-up for each dispenser size
  • Note that different printers, print tolerances, and filaments vary, so even after the above testing for each dispenser, some magnets may be a little tight or a little loose depending on your printer, calibration, and filament

About the Profiles

1. Please use the “Designer” profiles as they guarantee the latest files and version with all new magnet sizes and features. The Designer Profile(s) will be listed at the top.
2. NOTE: The “Designer” profiles are organized as a single profile per magnet diameter. Currently there are 15 profiles and are named with the magnet diameter up front, i.e., “6mm Diameter Set - Version <x>.<y>” contains all of the 6mm diameter dispensers of various magnet thicknesses.
3. While the other profiles may be ok, their file / update version may be out of date. So if you want the latest sizes and model improvements, please choose the top “Designer” profile(s).

Accessories

Be sure and check out some nice accessories that other folks have created to work with these dispensers.

• SKADIS Mount Holders - Looking for a Skadis peg board holder for the dispensers? Here's a very nice one made by @MakerCameron. Thanks @MakerCameron !
• Gridfinity Holders - Here's a nice set of Gridfinity holders that you might like to go with the dispensers. Thanks, @mcclajb! 
• Tip Caps - these are nice caps for the dispenser tip. Not only do they help keep the magnets contained within, but they also protect the tip. Additionally, they are labeled with the magnet size, which is nice. Thank you @onegotowned !
• Vertical Workbench Stand - This is a very nice stand for select diamagers made by @nickramsey57. A number of folks have asked about stands / organizers for the dispensers, so this model will likely be useful to a number of folks. Thank you @nickramsey57 !
• Vertical Workbench Stand (parametric) - Here is another very nice stand made by @RevHazlett. You can specify the dispenser sizes that you want it to hold and then generate, making it customizable to your needs and the common magnet sizes that you use. Thank you @RevHazlett!

   20. 20x1mm
   21. 20x4mm
   22. 20x5mm
2. Profile reorganization to accommodate all of the sizes. Each magnet diameter now has a dedicated profile. It was no longer possible to place all of the sizes into a single profile due to the 36-plate limit for a single profile.

Version 5.4: 2025-06-07

1. New Dispenser Size Added
   1. 8x1mm
2. Note: you can find the new size on it's respective 8mm plates.

Version 5.3: 2025-04-26

1. New Dispenser Size Added
   1. 10x5mm
2. Note: you can find the new size on it's respective 10mm plate.

Version 5.2: 2025-04-08

1. New Dispenser Sizes Added
   1. 6x1mm
   2. 6x4mm
   3. 10x4mm
2. NOTE: you can find these new sizes on their respective 6mm and 10mm plates.

Version 5.1: 2025-02-28

1. New Sizes Added
   1. 12x5mm
   2. 15x5mm
2. NOTE: you can find these new sizes on their respective 12mm and 15mm plates.

Version 5: 2024-04-21

1. Emboss the magnet size text on the Barrel (see photos), allowing one to view the size from the side, and also allowing one to print all of the barrels on a single plate and not get the barrels mixed up as to what size they are for.
2. Include the magnet size text on the Slider (see photos), allowing one to print all of the sliders and caps together on one plate and not get the sliders mixed up as to what magnet size they are for. Also provides additional text identification of the magnet size within.
3. Include 11 new magnet sizes:
   1. 3x1mm
   2. 4x1mm
   3. 5x1mm
   4. 7x2mm, 7x3mm
   5. 8x4mm
   6. 10x1mm
   7. 15x2mm, 15x3mm
   8. 20x2mm, 20x3mm
4. Re-organize the plates so that they are a little easier to manage. All dispenser sizes for each “diameter” are spread across three plates now - the Barrels, the Red Caps and Sliders, and the Blue Caps and Sliders. This allows one to “print-by-layer” instead of “print-by-object”, and the text also comes out better. Additionally, it is now easier to construct a plate with all of the size variations on 3 individual plates and print them all at once.

Version 4: 2023-12-26

1. Fixed an issue where the smaller diameter magnets such as the 2mm, 3mm, and possibly the 4mm magnet diameters could inadvertently slip through the vertical barrel slider stem slot. Prior to this update, the slider stem was a fixed 3mm + tolerance width. With Version 4, the slider slot is now dynamic based on the magnet diameter. So now, the smaller diameter magnets are captive within the barrel and cannot slip out inadvertently.
2. Tighten up the tolerances between the “slider” and the “barrel” for a better fit and smoother operation.
3. Use the Profile: “Version 4: All Sizes …” for the latest from this update.

Version 3: 2023-12-22

1. Added additional magnet sizes
   1. 2x1mm, 2x2mm, 2x3mm
   2. 9x2mm, 9x3mm
2. Text is now added within the Fusion 360 Model File, eliminating the need to add the text using Bambu Studio
   1. Ensures consistent text placement and easier colorizing of the text
3. All plates are included for all magnet sizes, two dispensers per plate, print sequence: print-by-object

Version 2.1: 2023-11-28

1. Added additional magnet sizes
