What were the costs? Printer? Consumables? Design/pattern?
We got the Creality Ender 3 Pro which runs about $300. This comes tested from a US company. Filament runs about $20 for a roll that weighs a kilo. Depending on the print, you could use several meters, getting you quite a bit off of one roll. So far I have printed 3 Nerf mods, the aircraft, baby Yoda and a couple of test prints. Still have most of the first roll left. Each print so far has cost less than a dollar in materials. You can download files of all types in Thingiverse and MyMiniFactory. Those are the two that I have used so far.
Now, time spent doing this is something else. The airplane model had a total of 14 print hours and the baby Yoda was 17. If you can deal with that, not too bad.
Already considering how I can sneak another past the wife. Would allow me to print what I want and what my son wants at the same time.
