#Questions Dear Community, I recently purchased a BambuLab P1. I am concerned about a hole in one of my models that is not printing correctly. The hole is approximately 12 cm long, has a diameter of 8 mm, and is flattened in one area. The idea is that I can store a Samsung SPen in this hole. The following problems arise: What is the correct diameter? I designed the hole with a 0.2 mm oversize. The pen does not fit inside. How much oversize do I need to take into account in the design? The surface around the hole is not printed correctly; long threads are visible. I would be grateful for any advice!
