Sigma BC900 Bicycle computer holding plate adapter plate bike mount

I recently bought an old bike which included a Sigma BC900 bicycle computer for logging speed, distance etc. After some cleaning, the computer itself worked like a charm, however, the plastic mount has seen better days. There is a small plate inbetween the main mount and the computer itself which was very brittle and broke when I inserted the bike computer into the holder.

So, I decided to design and print a replacement part. The shape is not too complex, however, there are two small hooks and two bumps which are very small and delicate. Therefore, recommend printing the part in PETG with 0.1 mm layer height to get a good resolution. I also printed the part sideways (see the attached GCODE and 3mf files) with only some small supports. This will make sure that all areas of the model turn out well and also, the layer lines are in a direction which provides a good rigidity.

For mounting, take your time. You need to use a little bit of force to snap the plate into the holder, but do not apply to much pressure or the hooks might break. I also had to use some fine pliers to slightly squash the two bumps so they would fit into the holes on the computer itself, but depending on your printer and settings, your mileage may vary. I recommend doing a "dry test" before inserting the plate into the main mount.

If anybody out there is also still rocking one of those old bike computers and needs a replacement for that plate, plese print it and let me know how it turned out! :)
