I bought the STL and had it printed by a company, as I don't have a 3D printed. The mod worked very well, giving me stepless adjustment without shifting. My print is not 100% smooth, so it take a bit of effort and care to tighten the grind size, but still my grinder is much more enjoyable to use after this mod.

Its working fine at the moment

I just received my SD40v2 and installed this mod. It works very nicely. Stops at every mark on the scale and locks in tight. As for longevity and durability, time will tell, but so far, so good.

I'm looking to buy the sd40 v2 Stepless Grinder Tuning Kit mod with the worm gear. How can I go about it?

Hello! You can find this mod on Cult3d or send me a private message.

Hello! Glad to hear positive feedback, thank you! My mod is printed with CoPET and has been working for three months with daily use. I don't see wear and tear at the moment, but if there are any changes, I will let you know, fix the model and send the corrected files for printing.
Thank you for your support!

Hi Chameleon0ff! Love the mod! I originally printed with PLA and it obviously didn't hold up but it did last me a few weeks. The only issue was the base. Since I've tried multiple times to print the new base you uploaded recently and I'm really struggling. The part of the base that holds the worm bracket and worm to the base keeps breaking off for me. Can you check the dimensions of hole for the nut to hold the worm to the base? It seems smaller than the one that you glue in to stop the worm from rotating. It also seems that it now dips down a bit (where the nut is screwed in) in the new version as before it was flat with the base. I think there could be some improvement in durability and strength as well if you could make both of those pieces by the worm bracket a bit thicker so there's more holding it to the base. I was going to try myself but I'm not great at Fusion360 (still learning). I've also tried calibrating my printer (Anycubic Vyper) but given the hole for the nut you glue in place fits, I don't think that's the issue. I also think there could be some benefit to adding some thickness to where you glue the nut in place as well just to give the nut somewhere deeper to be stuck in and glued to. Looking forward to hearing from you!

Hello! Thank you for your feedback!
I replied to you in private messages for a more detailed discussion

Hi to all! In addition to the stepless mod, I created an additional mod that allows you to better fix the cup and grind the coffee directly in the portafilter. The model is also for 3D printing with base materials such as CoPET (PETG) or PLA. Installation requires only 2 M4x20 round head screws, one 15x8x4mm magnet and one d6x4 magnet.
For all readers of the Home-Barista, I also provide a promo code "HB10" (without quotation marks) for a 10% discount on the purchase of both coffee grinder mods.

All money from the purchase of this mod (link to the purchase of the mod) goes to support the Ukrainian army, which is constantly fighting against the russian invaders. You can also support Ukraine by donating to such funds as the Serhiy Prytula Foundation, Save Life, United24 and others.

Take care and all the best!
