I bought my first 3D printer in 2016. It was an Anet A2, which arrived in a box that resembled a “Meccano” set, with hundreds and hundres of little metal parts and a few motors. It took a couple of days to assemble it, but several weeks before it could print anything useful. This was an ideal machine for operating on the boat for a few reasons; it ran on 12v DC power, so I could hook it straight up to the battery on board SeeBeeZee (bypassing the provided power supply), it was light and could easily be packed away, and it was made from parts that were easily replaced. However, build quality was not great, but I kept blaming myself for that. It wasn’t until I replaced this printer with a Bambu Labs A1 Mini that I realised that it was not me that was the problem, it was the printer.
