Has a hole for 5mm ( 3/16") steel pole dodwn the handle and up the whole model for reinforcements, also includes holes at joints for filament guides. It's a little hacky of a project as it was designed for 3mm LED's , but 5mm LED's work as well, I would recommend having a 3/16 drillbit or slightly bigger ( or print at 101% maybe? ) because the poles are really tight to put in ( you dont want them to be too loose ) , and if you want 5mm led's just drill the 3mm holes bigger , model has a channel down the middle and to the magazine meant for wiring + battery in the magazine + switch on magazine. magazine might be best printed @ 97-98% if you don't want to put in manual work.

Recommend using silk purple ERYONE filament as you won't need to paint the base colour.
