Thumbwheel for M5 jam-nuts

youmagine

I have a situation where the countersunk head of a bolt is obscured and I'm unable to utilize a screwdriver or allen key to adjust it, so I had to devise an alternative means of gripping the bolt. To accomplish this, I employed two nuts pressed tightly together to create a stable platform that can be grasped. However, due to the slight misalignment of the two nuts when jammed together, I was unable to integrate a plastic insert for both nuts, which would have provided greater precision. Consequently, I opted for a two-part thumbwheel design, secured with 3xM3x10mm bolts, allowing for easy removal and servicing of the bolt. For anyone who may find this solution beneficial or convenient, I've uploaded it to Thingiverse as a reference point.
