After some minor tweaks of the blade gap and safety bar offset, I'm calling this fully 3D-printed safety razor design complete. I wanted to design a razor that is easy to maneuver, provides good audible feedback, and would use readily available blades. The gap between the safety bar and the anvil is fairly large but doesn't compromise the blade support. This makes it easier for the lather to flow through and it is also easier to rinse. The efficiency is just below medium according to my preference and there is plenty of blade feel, but it's all non-threatening. A very smooth shaver for sure. I'm quite happy with the results, but I'll admit, it's not an easy print on FDM printers.

This is version 2 of my shaving brush stand. It is now a razor and brush stand. The added razor holder can accommodate most razors with handles up to 12mm in diameter as well as most brushes regardless of handle shape or diameter. This is a 3D-printed design. Soon, I will make the files available as free downloads for personal, non-commercial use.
Any recommendations regarding the best online place to get these razors printers? I'm not familiar with some of the terminology used in this thread regarding types of printers. Is it just a matter of finding a place that will print them and giving them the files? I see other intsructions on the link for thingverse. Do you need to specify what kind of material to use? Thanks
This really great stuff. Well done! And terrific that the files are made available. Thank you. You are slowly luring me into the future!
Guys. I've never really paid attention to the references to 3D printing. At a basic level, Is this about using a printer that is fed material other than paper to 'print' a picture of some object in 3d? Does anyone here actually own one of these printers? How long has this been a thing? Paul
3d printing has been around since the late 40s but for the hobbyist, they became more available in the early 2000s, and now they're everywhere, are fairly inexpensive, and are easier to use. In the most basic operation, a 3d printer is nothing more than a micro-sized hot glue gun that is moved around by an XY plotter forming and stacking one layer at a time to form a dimensional object. The picture below is of a large-scale concrete 3d printer printing a full-size house. You can see how the layers are formed on top of each other to give them dimension.
That is awesome! I had no idea we're going back that far! Thank you for the education. I really appreciate it! Paul
Well, this is going to take a while, but it just might turn out to be useful, and maybe even fun at the same time. @Ron R posted a picture on one of the forums of his razor and brush stand/holder with a very practical built-in DIY "Blade Use Counter", and I just had to steal his idea and put it to use somewhere. A while back I came across some old vacuum tube radios at an antique mall and didn't think much of them. Turns out there's a big demand for certain models, and the prices keep going up. The RCA Victor AM radio from 1956 is becoming a rare find, so, I thought, what if, just what if something with a big dial on a small scale could serve a purpose? Below is a very rough draft of my 3d model that is far from being finished. It's a mini 1956 RCA Victor AM radio ( about 3.5 inches wide ) that will help track how many times a blade has been used by turning the dial to the corresponding number, and it is also a blade bank. Once complete, it will be an easy 3d print that will not require supports. Thanks for sparking a useful idea, Ron. A rough model of RCA Radio - Blade Use Counter and Blade Bank
Just wow! What an amazing project! Your model looks really good! I’m looking forward to seeing a photo of the finished product! paul
Looks like a practical interesting blade bank, never seen one before, one of a kind in the world. Have some fun designing it!
Cool design, Roger. Only two issues: - what if I have more than one blade on the go... - what if I shave with a Personna 74 injector blade and get over 20 shaves out of it
I'm making progress. I should have it complete by tonight. I'll make the STL files public tomorrow after I run a couple of test prints.
This fun little project is complete. Blade banks were quite common in the 1950s. They were often promotional items or figurines that could also be used for display. Unfortunately, most of them were designed for one-time use only, and once they were full, they would end up in the trash. This is a vintage RCA Victor radio-inspired blade bank with a blade use counter that can be reused over and over again. To track the number of shaves per blade, all you need to do is turn the tuning knob to the corresponding number. To open the blade bank, simply unscrew the center knob on the tuning dial and dispose of the used blades properly. This blade bank is completely 3D printed and doesn't require any additional hardware for assembly. I've made the STL files public, and they are available as free downloads for personal non-commercial use at the links below. https://www.thingiverse.com/thing:6474516 https://www.printables.com/model/756303-blade-bank-and-counter-1956-rca-victor-am-radio
Roger, Very nice 3D printed Radio spent blade box mimic scaled down in ratio. That is interesting how well the threaded knobs turned out! It is not easy to machine a similar thread IMO internal and external threads with a aggressive pitch yet you make it look so easy. Excellent workmanship using technology and your background knowledge in manufacturing.
