Threaded Brush Cap for Desoutter Drill Gun Heavy Duty Type b.1/4"

After seeing a part I modelled to fix a wire stripper - A friends asked if I could print a replacement for a Bakelite part in his grandfathers 1950s Vintage drill.

It took a lot of learning about thread dimensions and print tolerance, but it ended up pretty nice and fitting perfectly.

This will work for the brush plug (not sure if that's the correct name) on the top as well as for the one in the end of the handle.

Please post a make if you print it! - I'll be stoked if someone actually needs this.

I'm new to modelling - any feed back appreciated!
 

Note: I printed this with a 0.2 Nozzle and .08 Layer height to get detail fine enough to screw in as well as the original. You can print will 0.4 and thicker layers. But I found that whilst it technically works, it only screws in about half way.

Print Settings:

• PETG+
• 0.2 Nozzle
• 0.08 Layer Height
• 20% or Higher Infill
• It has a curved top to match original so I print with the hollow side down and added a manual support in Cura - Wasn't really needed with PLA though and may not be needed with PETG but I didn't try.

Finishing:

• I Sanded the top down and finished with steel wool to remove the top layer lines.

Required:

• 1 x Old ass drill

Installation:

• Hand screw in or use wide flat head driver
