Spanner for self-printed Z-couplings

prusaprinters

Since years I like to use this self printed Z-motor couplers with that I have good experience:https://www.thingiverse.com/thing:1651349So that I don't always have to use the heavy spanners from the workshop, I printed myself a few simple little spanners that are quite sufficient for the purpose.I printed them with 70% Gyroid Infill and they are sturdy enough to tighten the coupler nuts very firmly.If you like my design, please give it a Like and post a Make with a rating. Thanks a lot!
