First project - Zoom GFX-8 rotary knob

Had a Zoom guitar pedal with a missing rotary knob and, after searching the internet for a replacement, I decided to try PCBWay's 3D printing service to see if I could get a temporary replacement made up, having seen good reviews from YouTubers who had used their services in the past. After struggling to create a design (never used a CAD program in anger before and had to use AI to assist me!) I managed to put together a 3D model that was an approximate version of the knobs on the pedal. Was easy to upload and to put together an order for a few knobs to be printed, and the cost was very good. Model was approved quickly and, in a couple of days, the order was on its way to me. Was kept fully updated of the package's journey and got the rotary knobs about a week later. They looked great, but my model measurements were a little out (my problem, not theirs), so had to do a bit of sanding to get them to fit. However, once this was done they were excellent and worked perfectly. Really happy with the service I got and fully intend to use them again in future!
