3D Printing AeroTech Universal Delay Drill Tool dimension

[Richardx]

Hi all,
I decided to use AeroTech DMS for upcoming L1 cert flight and didn't realized I can't use RMS delay tool on DMS. Ordered the UDDT but it is coming the day after the launch day. Since I already RMS drill bit, I would like to 3D print the UDDT housing for 4 second cut just for this flight. I got some dimensions from the forum but wasn't complete. Could someone with UDDT verify the dimensions I have? Mainly need help with the inner depth dimension. I am attaching a sketch of what I have so far.
Thank you!

P.S. Again, I have already purchased the tool but it is coming after the cert launch day. Not trying to avoid buying it. Thanks

Perhaps someone at the launch will have one that you can borrow?

The DDT hasn’t always been a thing.

You *can* use a plain drill bit, removing 1/32” per second of delay change desired. 4 second reduction = 1/8” drilled.
Wrap the bit with masking tape at the correct depth as a stop point.
