This is a charging dock for a Wahl Lithium Ion Stainless Steel Trimmer
The charger cord is secured by the “plug” file using a m4x16 screw and a m4 nut, the nut slides into place.
I designed it to take weights ( https://a.co/d/1LAltJY ) You can weigh it down with anything really sand/bb's etc. you just need to add a pause if you want to weigh it down.
Printed at 80% infill for more weight, i used a .6 nozzle, but any size should work fine.
