Summary

Easy to build! All you need is to print some models and laser cut 5mm wood.
I used 8mm shaft 75mm lenght (2pcs) and linear bearings LM8UU (2 pcs).
I made it for this motor https://ru.aliexpress.com/item/DC-12V-Electric-Motor-Smaill-PCB-Drill-Press-Drilling-Compact-Set-10PC-0-5-3mm-Twist/32418721887.html?spm=2114.13010608.0.0.csKT3K, but any motor 28mm diameter can be applyed.
