3D model description
There are several press tools for the 32mm Fox fork dust wipers, and I've printed a couple, but using them I wasn't totally happy with the results, so I came up with my own design. This design works with the old style dust wipers as well as the new. The new dust wipers are really tough to install in the older forks, so I added a guide pin which reaches down to the upper bushing to help hold the dust wiper straight while it's driven in. Other designs you have to hold it something near flat and then hope it stays that way while you hammer it in. I also made the walls thicker so that you don't drive it too deep into the fork.
NOTE: The outer diameter of the press is larger than the outer diameter of the seal as this keeps you from driving the seal too low into the fork. You want the surface of the seal to be flush with the top of the fork. Some of the other designs have the outer diameter match that of the seal, which would allow you to drive the seal in too far, and that could be bad.
A remix of mine with the outer diameter shrunk down so it matches that of the flangeless dust wiper. The problem here is that now allows you to drive the dust wiper down into the fork, and it's not supposed to go that low. If you drive it down too far there isn't room for the foam ring, and if you drive it all the way down to the top of the bushing, you will likely have a beast of a time removing it later.
Same as above, sized to match the OD of the dust wiper which would allow you to push the dust wiper too far into the fork. The outer diameter of mine is intentionally larger than the dust wiper to prevent this. Cool animation, though.
This is a simple design with a larger OD to prevent overdriving the seal but doesn't have the guide pin, so you have to keep it square by hand. That can be tricky with the new flangeless seal design.
The side walls on this one were very thin and broke when I hammered on it installing new style wipers on a 2014 fork. Worked fine on the older dust wipers with the flange as those were much easier to drive.
Nothing particularly interesting here, same idea as the previous.
Other fork maintenance tools:
Top cap remover socket - very simple design, this wasn't designed with printability in mind, no matter how you slice it (literally) you're going to need support material.
Another top cap socket which is more printable if you print it upside down.
I have my own top cap remover socket that I'm working on but so far I'm not 100% thrilled with the results. Hope to have it sorted soon so I can post it.

Note: I wanted to try Cults3D as a possible alternative to Thingiverse, but after giving it a bit of a look, I'm not super impressed. Feel free to visit my Thingiverse page if they can manage to keep that site running:
I went to school as a mechanical engineer, and got interested in 3D modeling, specifically the SDRC I-DEAS CAD/CAM software system. This interest got me my first job working for a CAD/CAM reseller doing pre and post-sales support. I was lucky to be involved in 3D printing in the early 90s - for a demo of rapid prototyping, I modeled the mouse from my HP-UX CAD workstation and it was rendered via stereolithography. I still have that model, but across the years I stopped using CAD and moved to systems administration. Now that 3D printing is affordable and mostly reliable, I've gotten into it and am having a blast. I printed all the usual cute little trinkets and tchotchkes, but quickly got bored of that. What I find most interesting is needing something, then spending a little bit of time in a CAD program and soon after that having a real, functional version of the part in my hand.
I'm a cyclist and bike mechanic as a hobby and a side job, and have found endless applications of 3D printing to both bikes and bike maintenance. Coworkers have also come to me with many varied requests, each of which has been an interesting challenge and an opportunity to learn.
I am constantly learning, constantly trying to challenge myself to learn new things and technologies, so hopefully as I progress my designs will continue to improve.
