10/12/2022: Uploaded the correct nut and lead. The first ones were mirrored.

The drill was inspired by push drills such as this one by LoboCNC: https://www.printables.com/model/132326-push-drill-with-adjustable-chuck

The chuck is based on this one made by BManx2000 with a slight modification to the shaft: https://www.thingiverse.com/thing:2625085

This is my third and best iteration of the model.

BOM:

2x 608RS Ball Bearings (8x22x7)

2x 693ZZ Mini Ball Bearings (3x8x4) (You could print a bushing of the same size instead)

Misc. Screws (I used what I had on hand, mostly M2 and M3)

Spring or elastic band (The stronger the spring, the stronger the drill but it makes it harder to pull. Experimenting is key. I don't have a particular model to recommend as I modified a spring I found)

Printing:

PLA (mostly)

PETG (I used PETG for the chuck as it gives a better grip on the drill bit, PLA should be fine though)

I printed with 5 walls thickness with a 20% infill, but these can be experimented with.

Supports are needed for most parts, it will be obvious.

Consider buying me coffee!
