These are the TNT print-in-place Fidget Detonators!
Both metal and wooden versions are included in this download!
Added a STL + 3mf sign and also the handles that go inside the rod.
Please read the printing instructions!
The internal spring is supported by small strings that connect to the walls - This is to prevent it and the handle from moving side to side, when the print completes just push the handle with some force inside (there are 2 visible strings between the cover and the handle)
change your Bambu Slicer wall generator to ARACHNE for these strings to print - It's a safeguard although I was able to print them without issues also with classic - Without the supporting strings. In CURA you don't have to change anything.
The internal spring may warp upwards a bit while printing and might make some noises hitting the nozzle - Don't worry as long as it's not breaking or snapping and fusing with the walls...
