It seems like you misunderstood what this was meant for. The original model has larger holes meant to drill directly. This was remixed to be used as a center punch / pilot hole guide (as the title says) for the center punch I had. If you have a different one and tell me what hole size you need, I'm happy to adjust it, maybe someone else has the same. I can't change the print profile to something stronger, as it's already solid walls without infill (and it worked for me).
