3D Printed Drill Stop Collar




Introduction: 3D Printed Drill Stop Collar

About: Interactive technologist/industrial designer

If you need to drill several holes to exactly the same depth, these are pretty commonly used tools in the shops, you can also buy steel ones from online/shop.

Heres a link from McMaster Carr

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Model on Autodesk Fusion 360

I made the model on autodesk fusion 360. The model is fairly simple, I made the hole for the set screw a bit smaller from the measurement from between two sides of the threads

Step 2: Slicer

Use any slicer that works for your printer

in my case, I'm using a ultimaker printer, so I use cura to prepare the print file

Step 3: Set Screws

I got my set screws from a assorted set from amazon, you can also get it from McMaster Carr.

The set screws from the set just say 1/8 dia, I assume its either 5-40 or 5-44.

The set screws should thread in with a bit of resistance when you first drive it in with a allen wrench.

Step 4: Put It on the Drill Bit!

Slide it through the drill bit. If it is too tight, i suggest loosen the set screw, but it on a vice grip and run the drill bit in a drill until it slide easy

Step 5: Files Available on Thingivers

    I see you've used PLA plastic. Are you afraid of it ever melting from the high temperature the drill bit reaches while drilling?

    PLA start getting soft above 150 degree celsius and I am only using them for up to 3/8 inch bit so it should be fine, at least so far i haven't counter any problem, you can also use other material as you desire, the maker space i have access to only provide pla so thats what i use. also pack drilling also prevent over heating

    Clever idea. This is much better than my usual technique of using tape.

    I was thinking of exactly the same thing. Though sometimes I use sharpy when I don't have a stop collar for the drill bit i'm using, And I'm not using a drill press with a mechanical stop. Suddenly all my drill bits will have stop collars to keep em out of mischief. (thanks schou2 for creating this top tip)

    tape is also a valid solution. But this you have more indication of when to stop.
