About this Product

This is a custom bottom bracket for the Hario Skerton Coffee Burr Grinder (same as Kyocera CM-50) designed using Tinkercad.

Here's a little Vine to show it in action.

Featured on the Shapeways blog!

Assembly:
· When you receive the print, bend it at the snap points and pull the two halves apart
· Disassemble the grinder and mount the bracket halves between the plastic body and the metal ring that holds the outer burrs in place.

More detailed instructions coming soon!

Dimensions

IN: 2.15 w x 2.144 d x 0.394 h

Hi @jpagonas , the material used in this print is not considered food safe by Shapeways, but as it applies to coffee beans I think its perfectly fine, since the grounds are being strained during the brew process anyways. I've been using this mod on my grinder for a while now and haven't noticed any negative effects to the brew. Cheers!

is this product food safe?

@allensantos thanks for the tips, glad it's working for you! You are correct in that removal of the bottom nut is not necessary with this mod.

This thing is pretty neat and seems to keep the grinder code centered for bigger grinds. I don't know how others installed it, but I didn't want to mess w/ the nut at the bottom of the grinder core. So I kind of lined everything up upside down w/ my fingers: upsidedown skerton top -> Shaft -> This -> grinder ring -> plate -> grinder cone. When I went to screw the plate back in, there was a click and things seemed to lock into place.

@greggschroeder awesome happy to help! Let me know how it works out or if you have any other questions.

Thanks for the good description of the difference! I think I will order one of yours. It is a very cool idea and addresses the main concern and dismay that has plagued me since I bough the Hario. I use a Compak and Rocky at home but I use the Hario at the lab where I work multiple times a day. All I use it for is pour-over grind so this mod fits my use perfectly.

Hi @greggschroeder good question! I've never used Orphan Espresso's adapter but I am definitely familiar with it and how its installed. The main difference is that because mine splits into two halves, it does not require that the inner burr be removed from the central shaft. The reason this is required for the Orphan Espresso adapter is that in order to have a perfect fit, the adapter needs to fit around the lower half of that spinning shaft perfectly to prevent it from wobbling back and forth (the whole point of these adapters!) but the TOP part of the shaft where you would think to slide the adapter over, is where the screw threads are, which is THICKER than the bottom part. So, because my adapter splits in half, there is no need to remove the bottom burr (which can be tricky to reassemble) in order to get it into place. :) Hopefully that helps explain the difference!

@erinautomatic How does this design compare to the metal ring design offered by orphanespresso? That installation video of his looks like a very tedious process but does ensure the correct fit. I would imagine that the installation of yours is much simpler as you are not messing with the burr itself. Does this leave the possibility of an imprecise grind due to poor QC on the Hario's build? Just weighing in on the pros and cons as you may view it having designed and worked with this. Thanks,

just got mine in the mail and put it together. This works great, just helped me a nice french press. I like that i don't sacrifice function with this, i can still dial it down to espresso for when i get the urge.

Considering posting a link to this on the CoffeeGeek forums to see if I can get some more testers :)

@Ikbendewalrus I've been using this in my own grinder for a solid 5-6 months now and it's been great. I've had a few friends install it as well and it seems to be working well for them too. I'd still like to do a v2 at some point that makes installation a bit easier and improves bean flow (sometimes you have to give the grinder a little shake if the beans aren't feeding correctly), but otherwise I think the grind consistency is noticeably better with this mod installed. Still, if you get one please let me know how it works out and if you have any suggestions for improvements! Cheers.

From Orphanesprzsso but cheaper and more simple?:) *sry, pressed 'post' a little too soon just there:)
February 15, 2014, 11:20 pm
I'm curious how the buyer fared:) So this gives a consistent grind size to the Hario mill? Even for the coarse grind i take it, so this is pretty much the mod fr

@PlanetExpress Awesome! Let me know how it works out or if you have any suggestions for improvement. Cheers.
