Oh boy, I think I watched too many of William Osmans videos lately. The version shown is a prototype where the hinge didn't print very well. I fixed that in the uploaded files by using another type of hinge, but I am not willing to print another one of these. I leave that up to you guys. Feel free to upload a picture if you really printed it.
It should work the same with most power drills that have batteries which are under 8cm wide and 8cm from the printed case apart. Originally the ring was there to press the holders onto the fork/spoon, but tape just worked better for me. I also recommend using a long hexagonal bit instead of the stud.
The holders need support, the rest doesn't. The stud needs 100% infill, if you use it at all. Bolts with 40%. Threaded parts in 0,15mm or 0,2mm resolution.
