3-D printing small parts
One of my younger, more tech savvy coworkers was talking about 3-d printers the other day and I asked him about making some of the plastic feet for my Zefal HP pump. He had a favorite site for open source patterns for his other projects, so I did a quick search and lo and behold, they had the pattern. He ran off a quick sample for me as a test run and it was pretty good, but he is going to tweak it a little for a better fit. He is using as a learning exercise to get more experience with adjusting his printer. I'll post a picture when I get the final version.

Yeah, 3D printing is great for that kind of thing. There's a gazillion little bike parts that could be recreated this way. I'm thinking of the plastic quick release on certain early 1960's GB brake levers, for example. What about a Simplex derailleur? Some must have made those by now....

I put my BIL to work when he was bragging about getting one. He made me a dozen Cannondale toptube guides out of ABS plastic. They're kinda ugly, but look like they should work. I gave a couple sets to the co-op as I figured they'll get a "test" frame sooner than I will.

I find it odd that we don't have a section for 3D printing of bicycle related items. It can be incredibly hard to find bike .stl files on some of the web sites. When I find or design a bike related item I try to post it on the bikeforums site just in case there is an interest. And then again there are a few designs I am only interested in releasing to the bikeforums Klan... Ha
Considering the fact that a lot of bikeforums members are from the engineering field I am pretty sure many members own or are well familiar with the 3D design process.
Yep... It's a void that needs to be filled. I am thinking it should be made out of ABS or Nylon. Then again you could perfect the 3D print in PLA then port the .stl over to a CNC machine for aluminum. fun, Fun, FUN...
My little Creality-Ender3 was given to me for Fathers Day few years ago. It has been fun. You can get a refurbished one for less than 100 USD on ebay now days. Small 3d printers can very finicky till ya get down the settings. I use Linux based free software (No Bill Gates or Apple). They are not much harder to operate then getting an old COX 0.049 engine running though. Hers a pic as requested...

As long as we are making a wish list I could sure use some of the plastic nut caps for the Simplex quick release.

Quick search shows they have three designs for Schrader to Presta rim inserts. Gonna check if the library still has their 3d printer

this is a RC vehicle wheel my kid printed
he printed a 'plug' for a bike stem (expander bolt hole) recently - looks like a factory part (sorry - no picture)

DIY 3D printers are great, but you're limited somewhat in materials. There are many sites that you can upload STL files to and have a part back in less than a week.
Going to a professional you can get high strength plastics in Ultem or PEEK, which rival aluminum in many aspects. Metals are available as well, but cost can be a factor. Most places can also hand-finish the part to remove the printing artifacts.

Printed a test bar plug to try and hopefully print more for few of my mountain bikes. Hoping to do some in different colors and design some logos to put on it.
Some of my other prints in the background...

I think if someone could do a run of Cinelli Grammo stem top caps, they could likely make a few bucks selling them on eBay. Easily $30 a pop.
