PrintrBoard Mount With Relief
V1 is the model in the pictures and v2 uses less plastic. I printed the one pictured but, I haven't printed v2 yet. They both have built in strain reliefs that can be secured using small zip ties.
These are a work in progress. If you need any small modifications to the design, let me know and I will see what I can do. I will be making one similar to this for Printrbots ExtrudrBoard. I plan to eventually add a top with a fan mount.
Update: I added version 1.1 which has holes to be mounted on Printrbot Simples platform. Version 2.2 is the same but uses less plastic to print. I also added a new version with longer releifs.
