I’m about 3 weeks into ownership of a Creality Ender 3 S1 Pro. So far so good, apart from stuff falling off the bed! Tramming your bed (“levelling” is a misnomer) is vital to make sure everything is parallel, but you engineering types already knew that didn’t you! Make sure you preheat the nozzle and bed before you do any tramming or auto-levelling, to account for any thermal expansion.

Yesterday I had a delivery of PETG and TPU to try, after getting started with PLA. I also bought some cool two-tone PLA but like a moron I bought 2.85mm stuff which doesn’t fit my machine. Live and learn.

What shell thickness and infill are folks using for forming dies vs. something like a tube block?

Just printed off a few tube blocks for a rack I’m making.

PLA, 0.4mm nozzle, 0.2mm layer height, 0.4mm width, 0.8mm wall thickness with 4 outer walls, 20% infill, 104% size in the slicer to accommodate any shrinking. Seems to work pretty well holding the tube in the vice. No problems filing with it but uncertain if it would hold up to a milling machine.
