I purchased these StarTastic Laser projectors on amazon for christmas this year and was sadden to see one of the boxes was missing the mounting stake! A little 3D modeling, a little 3D printing and I had my replacement. I used PLA and it lasted through the pacific northwest rain, snow and even some sun! The nubs that are used to lock the light into different positions show up in simiplify 3D but didn't actually print or more likely didn't stick, probably should have slow the print down a lot for that step. Even with out the nubs you can just tighten the bolt down to hold in place! Pring nubs side up with low density support material. The print doesn't need to be pretty, you are going to stick it in dirt. I did 25% infill but it probably doesn't matter, but I am guessing 3 shells is important for strength when tighting the bolt and sticking it in the ground.
