You might need to create one ;-) We can zap you :-)
Zaps are always welcome 🫂😁
if someone contributes, I need a more transparent solution

What print settings do you use? lid fit is a bit tight. 
The tollerances really look too tight … i used a .6 nozzle and no particular settings
I think I have to improve the lid
I printed at 0.2mm and 15% infill with a 0.6mm nozzle. Typically should leave 0.2 to 0.5mm tolerance - is there any tolerance in the size of the tabs in the lid?
NB It’s possible I need to print a calibration cube and check my printers accuracy.
i will upload a new .stl in a few minutes 😊
Broughts these bits with me - except I brought the wrong screen! D’oh :-( 
oh 😳😢
