3D printed shaving stuff

I just uploaded the STL file for this 3d printed MADE RITE 203 shaving brush on Thingiverse

This is a Made-Rite 203 shaving brush I recreated a while back. I find this design to be quite unique actually. Once I got my caliper going, I realized that this handle design was breaking all the rules of symmetry, and for good reason. On the original, the bottom section doesn't have a single true curve and none of the flat faces run in parallel or point to the center of the handle. Instead, the flat sections come to a point far away from the handle. The top section has two vertical seams and the hole for the knot is slightly bigger at the bottom. What all this means is that the handle went through an incredible amount of machining just to accommodate the molding process. It seems that the bottom section can only be ejected from the mold in a vertical direction, and the top section comes off the mold horizontally as a half. The two halves are then fused together to form the top half making it possible for the hole to taper to a larger diameter at the bottom. Long story short, I'll be using this little piece of plastic with a newfound respect for yesterday's artisans and machinist.

Like most of my designs, this is a high-res, high poly count STL. If you want to get the most out of this design on FDM printers, set the minimum segment-length to the smallest setting and don't use auto-merge of nearby lines in your slicer. For SLA printers, print with 100% infill. It will cost more, but it will have a nice weight and feel.

Ok. Here's my first post on this thread. This lather bowl is one of my earliest designs. I uploaded the files on Thingiverse about two years ago and it has become a popular download. https://www.thingiverse.com/thing:3392930

I've also uploaded a scuttle version but never printed it.

I'm going to take a swing at getting the medium sized bowl printed. I've never done this before. I'm using treatstock.com and am not sure what material I should use. I would prefer something smooth that won't destroy my brush, so not the rough cheap material / finish. Ideally something that won't warp with warm water usage either, but I can work around this if necessary.

I find brushes incredibly boring, but those look nice. A very pleasing shape.
(A brush with a Merkur Progress knob - that's why I like it) :laugh:

That's awesome! I'm curious. Do you get to choose some of the parameters when ordering? By parameters, I mean the number of walls, infill percentage, location of the seam, layer height, etc.

Go play around with the site and you will see. Sadly, I can't find a vendor nearby, and the cost of shipping is often as much or more than the price of printing the object itself. But no, there doesn't seem to be detail to the extent that you're referring to.

On treatstock you can contact the maker before ordering.
I've done that, for example, to ask them which material they would recommend for my purposes.
If they are not happy to answer your questions, go elsewhere.

I like the lather channels, but this won’t clamp the blade for blade rigidity. The snap on top cap is clever. I guess if it gets loose over time, easy to replace the relevant parts?

Thanks, the cap doesn't snap on. It works like an inverted key-slot. To mount, you insert the cap and blade off-center then slide in place to lock. The tension from the blade clamp and two registration points in the center create a very positive grip.

Lol. Well, I also have a GEM style and a streamline the uses injector blades. Do they qualify? :laugh:
I'm a bit of an SE razor nerd. So, yes they do qualify.

I have, however, recently used some vintage Twin-DE blades with great results.
Basically, a slightly narrower than usual DE blade glued on top of a normal-size one.
Would they fit? They are 0.3mm thick, about three times thicker than a modern "normal" DE blade.
