A magnetic device for picking up steel pin media. Useful for cleaning up and/or transferring steel pin media during/after wet tumbling cartridge cases for the purpose of reloading.
The collector has a large spring-loaded button at the top which separates the pick-up cup from the internal magnets, releasing the steel pin media.
Non-Printable Parts List:
- 5x – 9.5x3.2mm disc magnets.
- 4x – 0.5x6x30mm springs.
- 1x – M2x8mm button head screw.
Print Recommendations:
- 0.4mm or 0.6mm nozzle at 0.2mm – 0.3mm layer height.
- 2 – 3 perimeters.
- Paint-on supports underneath pin-block lip on the pick-up cup.
- Add a print pause at the correct layer for magnet insertion during the print.
- PLA works great.
Note: The pick-up cup stem will start to wobble a bit as the top ⅓ of the stem is being printed, which may cause slight misalignment of the upper layers of the stem. All iterations I printed during design development still fit inside the collector body and functioned normally. Just something to be aware of and keep an eye on during the print. (The most recent one I printed — on a MK4 with input shaping — had no misaligned layers, despite the stem wobbling a bit during the print).
Assembly:
1. Slide the collector body (large blue part in photo) over the pick-up cup stem (large gold part in photo).
2. Insert all four springs into the spring guides at the top of the collector body.
3. Place the upper spring guide over the springs at the top of the collector body.
4. Place the button body on top of the upper spring guide, push down, and rotate until you feel the the button body drop into position. At this point, the button body should no longer be able to rotate. Install the M2x8mm button head screw. Be careful not to over torque this screw, as it is only being threaded into the plastic of the pick-up cup stem; “snug” is sufficient.
5. Test the action of the collector by holding it in your hand by the collector body and actuating the button several times.
6. Go wash some brass!
Change Log:
- 27DEC2023: Corrected M2 screw pilot hole diameter in the guide rod; previously incorrectly set as a clearance hole. Updated model and print files accordingly; added two additional print files. Updated description text.
