3D Printed Designs

Some of the following designs are using magnets. Modern neodymium magnets are incredibly strong for their tiny sizes. I recommend using the strongest of those very strong magnets. If you have a choice, get magnets with a grade of N52 (one of the highest grades avaialble). While weaker magnets might work, the designs have been tested with N52 grade magnets.
Also, neodymium magnets are very vulnerable to corrosion. They contain a lot of iron and can rust. That's why neodymium magnets are coated. They should be at least triple coated (NiCuNi — Nickel-Copper-Nickel).
Beware that neodymium magnets are not solid metal, but more akin to metal coated pottery. They can easily break if they are allowed to smack into each other.

My first attempts at designing 3D printed objects was an adapter for using modern GEM blades in old razors designed to use wedge blades. You can read an entire article on the subject.

I have coöperated with Tom White on some of his ingenious razor designs. The first project we worked on was “Tom's No Name Single Edge Razor”; TNNSER for short. I didn't pick the name. The original ‘TNNSER’ was a prototype machined from metal:

Tom then wanted to make a 3D printed version of the razor and I contributed a handle based on the handle of the ‘Enders Speed’ razor.

Print the parts at the highest resolution your printer can handle.
The razor might need quite a bit of post-processing (sanding/filing) to get a good fit between the base and cap of the razor. It's unlikely they will fit straight from the printer. Don't print this if you can't handle this step.
You will also need:

• One stainless steel countersunk bolt M5×0.8 20mm
• One stainless steel HALF hex nut M5×0.8
  If you can't find the half hex nuts locally, try searching eBay for “M5 thin half hex nut”
• A GEM style single edge razor blade

Another of Tom's designs is the ‘Wabbit’. It's a razor for injector blades and there are magnets in the head of the razor. Tom designed the straight handle (V2) and I created another ‘Enders Speed’-style handle (V3).

The cap and base of the razor head contain magnets to securely hold the blade and the razor parts together. The magnetes should be of grade N52. There are three options:

• One pair of rectangular magnets, ¹⁄₄″ × ¹⁄₈″ × ¹⁄₁₆″
• One pair of round magnets 3mm × 2mm
• Two pairs of round magnets 3mm × 1.5mm

Print the cap and one or both of the handles.
You will also need:

• Magnets - see above
• Superglue to glue the magnets in place
• Maybe a small file if the parts don't fit straight out of the printer
  Tolerances are tight
• An injector blade

A razor handle based on the classic Schick Type E/G injector razors from 1935 to 1955. This handle can either be used as a replacement for broken handles on vintage razors or as a handle for modern 3D printed razors, like the “Caerbannog” (see below).

Discussing the size and shape of the Wabbit's cap (which makes the shave angle steeper than I like), I had the mad idea that the Wabbit doesn't actually need a cap, as the blade is held in place by the magnets. Tom liked the idea and agreed to make the necessary modifications to the head of the razor. I was at the time designing a replacement handle for Schick Type E/G injector razors (see above) and decided to use it for this razor. The name “Caerbannog” is best explained on Wikipedia

So, yes, this razor has no cap. The blade sits on top of the head, secured by three magnets and two small tabs. And it actually works without a bloodbath — if you know what you're doing. Shave with the correct angle and no pressure. If you slice up your face it's your fault.

To print this razor you will also need:

• The “Classic Injector Style Handle”
• Three 3mm × 2 mm round magnets of grade N52
• Superglue for the magnets and the handle
• A small file in case the tabs are a smidgen too large
• An injector blade

One step up in weirdness from the Caerbannog is the “Slantibartfast”. (It's a ‘slant’ razor, ‘bart’ is German for ‘beard’ and I came up with the name pretty fast)
It's a capless razor, just like the Caerbannog, but it has a hinge to adjust the head angle. The hinge contains two N52-grade 10mm×2mm round magnets. This works surprisingly well.

The razor is still under development. The files will be available for non-commercial use.

I remembered patent US2834105 by Alfred Terenzi and decided to adapt the Caerbannog head to take an injector blade magazine as a handle.

A see-through replacement cap for the Eversharp Fashion Razor should look good. So I started designing one.
It is also the starting point for a cap/handle for the Eversharp “The Deb” razor, which is often available with a broken cap/handle.

Designing 3D objects is easier with freshly brewed coffee from my AeroPress, made from beans freshly ground in my Porlex Mini hand grinder. The AeroPress funnel almost fits on top of the Porlex grinder. Almost. I needed a solution to keep the AeroPress funnel securely on top of the Porlex grinder while filling it with coffee beans. The result is this highly sophisticated round thing:
