I really like the original Hmozdinkapp, but I could not get any downloads from the generator.
So i decided to re-create it in onShape. It's not exact replica, but seems to be similar enough to accredit the original work.
My recreated onShape generator can be found here: https://cad.onshape.com/documents/8027943ab7d93b4f8d46f1c9/w/10731b8f6f4f3a926e352706/e/0a808a63741005eb5d24eecd?renderMode=0&rightPanel=variableTablePanel&uiState=6781943200f2446cd49e5cae
I used those wall plugs printed from PETG and they looks pretty strong.
Although there was no real testing made on them and also every PETG variation can differ in strength, so I don't recommend using the on high loads and/or expensive equipment.
I needed to switch my favourite print sheet from Satin to Smooth ( https://www.prusa3d.com/category/core-one-mk4-mk3-s-mk2-5-s/ ) in order to get enough adhesion as the first layer can be quite tricky to print. With larger wall plugs (8mm+) it gets easier to print.
happy printing :)
