Sealant Nozzle Cap - Silicone Cap - Silikon Tube Verschluss

thingiverse

I hate it when the short used silicone cartridge is dry again next time... So here's a closure. To make it close optimally, simply put a rubber band on the thread in advance (not necessary). The closure is designed so that the rubber band is pressed inside and thus closes the tube perfectly. If you want to seal the cap extra tight, you can use a normal rubber band instead.
