Printing my first self-designed part 😬
Did it with OnShspe+Cura... haven’t used CAD software since 1996, which was ancient version of ProEngineer. Things have really advanced a lot. Browser+cloud-basedwith version control and all sorts of other crap.

Even this extremely simple part (2 circles, 2 extrusions) was a nightmare to figure out. Felt like a caveman.

Had 3 semesters of drawing as an undergrad (93-94)... 2 on paper drafting, 1 on Autocad 2d. Taught myself basic solid modeling on ProE my sophomore summer at my dad’s office (he ran the design department for a division of tata steel).
Clearly I’ve forgotten most of it.

Also kicked the tires on the online library stuff. Downloaded and printed this cat cookie cutter from thngiverse

This one is REALLY stuck on and won’t come off. 😭

Tried taking the plate off but it’s soldered to electricals... no way to just disconnect. Goddammit.

I give up. I’ve tried icing it, a spatula, swabbing isopropyl alcohol around edge, hammering gently from the side...

At this point I’m considering drilling a small hole so I can insert a rod and try to pride the damn thing off. It’s either that or give up on this build plate and get a new one.

Dammit. Drilling a hole and trying to lever it off didn’t work. Simply ripped the top off. This is with super draft low-fill setting

Okay. Got it off. I slipped a box cutter under one edge just enough to get spatula under it, and that was enough leverage to get it off. Done building directly on build plate. Gonna try either blue tape or kapton tape.

Well, no harm done except for one teeny scratch on build plate, which won't matter since I plan to tape it up now anyway.

I *think* the most likely reason I'm getting extreme sticking while most people seem to suffer from insufficient sticking is that my nozzle might be too close to the print bed, making my bottom layers too dense. See this thread

In the future, try to level the print bed so that it’s slightly lower. It seems like the bed is just slightly too close to the nozzle. It will be a frustrating process, but worth doing imo

The way to test this would be to run an experiment at different bed levels with the same print, and measure the force needed to get it off, but I don't want to... direct on plate is too temperamental for my tastes. Gonna try taped up approach next.

My older Monoprice came with a paint scraper spatula thing but I haven’t tested it on a textured bed. I’ve heard of folks using tape (masking, kapton) when the bed isn’t bendable.
