Toilet cleaning tab holder for concealed Toilets (Geberit 12cm)

I designed this set of a replacement cover plate and a toilet cleaning tab holder because I didn't want to buy the overpriced and overengineered original version (roughly 50€) and also not any of the 3rd party clones (around 25€). I had to put this on 3 toilets so designing and printing it myself wasn't just fun but also a bargain in terms of costs.

Printing both parts is quite easy. You should use a meterial that doesn't dissolve in water (PLA won't be a good fit here, I used PETG) but apart from that there's not a lot to watch out for.

Print the tab holder with the opening to the top. The heavy bridging on top combined with the thin walls might lead to a bit of a inset on the walls to the top but that doesn't keep anything from working fine. Could probably need some fine tuning on the printer or the source files to get rid of it.

Should fit 12cm high models of Geberit (at least Sigma-30 Series). Let me know if you find it fitting on any other model.

Important note: I attached the Fusion360 file for modification but unfortunately the file is quite a mess. The main sketch of the plate isn't made very well and likely needs to be redone. I didn't do a good job here. If you manage to redo it and want me to attach it here - kindly send it over. I will definitely give you credits for it. Otherwise just fork/remix it if you want.

Should I ever find the time to learn FreeCAD I'd also redo it there.
