Transferring this from the old forum. See the original thread here.
This is my 7th build 
Used parts:
- Venom Mach 1 Cannibal 78mm 74a
- 3D printed pulley with 32T and integrated bearing
- Torqueboards TB 218 trucks
- Globe Prowler drop through deck
- Custom reverse motor mount
- Dual Flipsky 6355 190kV motors
- 12S VTC6 battery
- Focbox Unity
- 3D printed enclosures
- Flipsky VX1 remote
Changes from the original plan:
- went from 12S2P with the idea of swapping batteries easily to 12S3P (currently working on this)
- got the pulley working with strengthening through screws (detailed below)
The deck:
It is my second build with this deck already. I sold the first one but I missed this deck, so there for another build. I took this from a scrapped longboard. I will sand and paint it completely but just after all holes for the inserts and stuff are done. Color will be something like the griptape. I had to cut the back of a little, so that the motors fit.
Here’s the progress of the deck
The enclosures:
As said, I originally planned to got for 12S2P (and did also 
) but ultimately designed the enclosure to be ready for 3P already before I finally drilled the deck. Had to make it two pieces because it’s bigger than what my printer can handle.
The case for the Unity also holds a battery meter. It is designed as small as possible because the deck gets very narrow at the back.
The motor mount:
I wanted drop through and a reverse mount because the motors won’t really have enough clearance in the normal position. And I guess it really looks so much cooler with a reverse mount. As for now the plates are solid stainless steel (laser cut). The trucks rings are 3D printed. With some more screws for strength they finally hold and work. But I’m planning to do some from aluminium finally as I do not have to worry about it again…
The pulley:
When I started that build (spring 2019) there haven’t really been pulleys for Venom Mach 1’s. @moon just started with his at that time. I went for 15mm wide belts and designed my own pulley. First version has looked like this:
It didn’t hold up that well on the first ride so I went for a different design. The weakest point have been the tiny flanks fitting into the wheel. So for version two I went with M2.5 screws to got into the wheel. Has worked for the whole 2019 season then. Looks like this:
When you want the 3D file, just DM me. I used 32T but other teeth counts are possible as well. Needs three speed rings between the bearing of the pulley and the wheel. I might change that to five that I can use one zealous bearing.
Older pictures:
Footstop from Roger Bros definitely inspired by @sofu s S3 build
Smaller 12S2P VTC6 battery
Look with single piece enclosure for 12S2P
Wrote it some time as ugly prototype
Assembly after the deck was finally done
Final looks:
Unfortunately the wheels aren’t that shiny anymore 
Upgrades I’m working on right now are the 12s3p VTC6 battery and the aluminium brackets for the motor mount.
Let me know what you think of this one
