Flux Dispenser 3cc v.2

Flux Dispenser 3cc v.2 A fresh take on an old idea When I made new nozzles for lubricating the printer, it instantly clicked — it was time to update the dispenser itself. To be honest, the previous version worked well enough, but I had a few goals in mind: improve the ergonomics, eliminate unnecessary post-processing, and… just see what my printer is really capable of at full throttle. That’s how the Flux Dispenser v.2 was born — a simple yet precise tool that’s genuinely satisfying to use. What’s changed? At first glance — almost nothing. But that’s misleading. The real improvements are in the details. I completely reworked the design from the perspective of ease of use and print precision. For example, I managed to print fully functional M2.5 and M3 threads directly on the printer, no post-processing needed. Who would’ve thought M2.5 could be printed at all? Of course, this required a finer nozzle and thinner layers. Yes, printing takes longer now, but the result speaks for itself — parts come together without any filing.    Design and Materials This time I printed the body and the plunger in PLA, and the feed wheel in ABS. Visually, the use of complementary colors creates a contrast I personally really like. But of course, you can go with your own color scheme. The entire design still prints fine even with a standard 0.4 mm nozzle — the only exception might be the threads, which could require a bit of cleanup with a tap. What’s with the ring? Great question. A lot of people ask why there’s an O-ring on the secondary plunger — the one with small holes and no sealing function. Simple: it prevents the shaft from spinning. When you turn the feed wheel, the threaded rod pushes the plunger forward or pulls it back, and the ring keeps it from rotating. It’s a small detail — but it adds a lot of stability. Why 3 ml? Because it’s convenient. I load the grease into the syringe once — and that amount is just right for a full printer maintenance cycle. The same 3 ml size wor
