This fly swatter newspaper handle is something I have designed quite random and it turned out great I think. This is my first print in place I have designed which works like a charm! I tested this thoroughly which you can see in this video https://youtu.be/gHDfA-dlWj4 I have created a new playlist in which I solve first world problems with 3D printing, enjoy watching!
I have printed it on a Creality CR-10 in a 45 degrees angle and it looks like this will just fit on an Ender 3 in this orientation. I think it is nice to have a couple of these lying around so you can get rid of these annoying flies. At first this looks completely unnecessary and you'll get some questions of why (at least I did :P) but you'll find out that this is a must have!
This should work with PLA but I have not tested this yet. I have printed it without support in a 45 degrees angle on the bed so it fits your build plate.
