QRP EFHW with Winder.
Print Profile(1)
Description
This is a QRP EFHW design I came up with to be really compact and easy to carry. This is really thin and light, so best to print it out of something flexy like PCTG or PETG. PLA would probably not do well.
I used 3DFuel Lime Green PCTG to print this build and it worked out really well.
