And often you can just sand a profile into a junk of MDF on the belt sander and it does the same job.

There are a lot cheaper printers that work well too but they are more of a toy than a tool i feel like. The Prusas are like the the cheapest option for a reliable workhorse.
+x Chris Rogers - 5/22/2020 6:02:13 PMYou can also cast-in-place sanding blocks with some packing tape on your surface, some polyester filler (Bondo) to take the surface shape and a wood backer to hold on to...I'm a big fan of the 3M yellow foam blocks and the Stickit paper too - the blocks are hard enough yet have some give. Not cheap but a great system.You can also glue acrylic sheet to softer foam to make a flexible-yet-hard block for curved surfaces. You want to sand (fair) with something that takes the shape of the surface you want to achieve - but no more - so you hit the high spots but don't over-sand the low ones.
