Aero Bottle Holder

paschmann

Another 3D printed bottle holder for my Canyon Speedmax. This is a raised bottle holder for between your arms and mounts a traditional water bottle cage.

The typical distance between for the mount holes on cages are 64mm. 2 100mm M5 bolts keep the mount attached to a custom made carbon fiber base plate.

SRAM Rival Crank Aero Cover

paschmann

After reading about some aero gains from Crank covers, I decided to try and 3D print one to fit on my SRAM Rival crankset on my TT bike. The curves and irregular shape/profile of the crank made it difficult to model, so I printed a flat surface, and used heat to mold it to match the profile. It is held on via zip ties.

The design was done using Fusion 360 and a front and and side profile reference image. I printed this on a Prusa MKII.

This was one of my first prototypes. Due to the low melting point of PLA, a heat gun pretty quickly warms it sufficiently to get it to mold into the correct shape.

This was the final version.

Daniel Stowe Mapping project

A friend of Rocky Branch Park (read: Legend) who has been a big advocate for trails in our area and helped fund and support the RBP expansion asked for some help while he was working on the Daniel Stowe Botanical Garden. They had recently expanded their trail system but didnt have any maps for the park. He reached out asking for assistance and I cam up with the maps below.

Its always great to visit these parks and places and see the small ways my volunteering has contributed and hopefully helped encourage more people to get outdoors 🙂

These maps ultimately start with a GIS terrain shaded map, and after doing some running/cycling, using the GPS tracks to align the tracks with the parks boundaries. Then meticulously going through each GPS track and plotting the vector graphics on top, and subsequently adding various features, callouts, legends or notes. read more
