detonator tube caps

thingiverse

Grab some 32mm corrugated plastic tubing – you won't need much of it. I managed to snag a piece from a guy installing my cable as they use it to lay cables in your garden. Next, spray the ends grey or print two end caps in grey – whatever's easier for you. Then, just attach them to the tube with some glue and secure the tube to the detonator box using zip ties. I printed mine at 0.2mm layer height with a speed of 60mm/s using PLA.
