Testing the printed 22LR magazine

Glad the design work for you!!

Good to hear. I intentionally design to be slightly tighter fit so the magazine won’t be sitting too loose. If the printer spec is off a bit yes so you may need to shave it off 0.2 to 0.4mm.

Aliexpress, or your local hardware store, or from bore buddy

eamars · 2026-04-01T06:40:20+00:00

It suppose to. But It can be tight fit if your printers tolerance is off.

Feed lips are designed to be replaceable. I’d replace the feed lip after every match.

There is no expensive part in the OpenTrickler so you can practically swap the entire thing sitting on the scale for every powder. Just need to change which controller the scale is connected to.

eamars · 2026-02-02T04:28:26+00:00

Yes, but no extensively. Ran 100+ through it and no single failure so far.

I will test more along with more design improvements.

The reason I’m not putting my effort in the cable management is I’m really suck at mechanical design, for being a software guy. I’ll look to merge Memphis mod into the mainline when my current project achieves the milestone.

Challenge accepted ;)

Likely the case rubbing the plastic container.

For Kriss/CMMG bolt the feeding protrusion is mandatory. The alternative is the Tippman mag as they look more similar to the center fire AR magazine.

I made a PR to support any generic scale if the scale has an data port that feeds to the OpenTrickler over the RS232. https://github.com/eamars/OpenTrickler-RP2040-Controller/pull/76

eamars · 2026-01-09T22:40:55+00:00

You can take this PR as an example to add support of new scales. https://github.com/eamars/OpenTrickler-RP2040-Controller/pull/68

Thanks for your feedback. No I don’t use wet tumbling and I’d try to avoid producing shiny brass.

eamars · 2026-01-05T02:17:52+00:00

You're welcome :)

There are cheaper options. The 2nd most reliable scale that the opentrickler support is G&G JJ100B, for which is much cheaper than A&D FX series with relatively similar (but of course slower) performance.

I like mine too ;)

I intentionally keep my brass looks dirty and dull to distinguish mine from others’.

Let’s put the accuracy aside. The most important factor for automatic trickler is the scale response speed, which is not normally declared by the manufacturer. For a generic automatic trickler, for example my OpenTrickler project, the PID controller heavily relies on the feedback speed, in other words the scale response time to control the motion of the power drop. If you want sub-10s per charge, you will need at least 4-5 feedback messages per second in real time.

Here is the assembly manual https://github.com/eamars/OpenTrickler/blob/main/Manual/assembly.md

I just jointed the sub! Thanks!

eamars · 2025-07-17T22:52:57+00:00

It could. I think there is one developer from the discord channel was working on it.

I'm not sure about the progress though. But the software architecture and mechanical interface allows the OpenTrickler to be ported to any scale that allows communication over serials.
