Alright. The source. This file on OnShape.
Remix and use derived part to your heart's content! There are four main tabs:
- battery mount- the basic, no-frills, single mount. No attachments at all. All of the next tabs use this as a 'Derived Part' and the foundation of their designs. Use this as a Derived Part in yours!
- underside mount. This was my original design for my Wowgo Skateboard and, with the added support ribs, works great! Without deck-risers the battery clearance isn't really enough, however, so I created the:
- topside mount. Perfect for adding ~12miles of range and/or 60A capacity to an existing board or replacing your existing battery altogether. This design includes 5.5mm eyelets for alternative mounting, perhaps to an eBike with a buck boost controller.
- duo mount. A simple back-to-back mount designed for non-skate uses. I use a 3D-print of this for charging– and break out the cell-balance pins.
- stacked mount hasn't been printed or tested yet. It's designed for the flexible PETG plastic and moves the batteries far forward on my Wowgo deck to help with clearance issues.
Skip downloading these STLs here (unless you've got my exact skateboard, just want to use the eyelet mounting points, or want a charger-mount). Go fork that onshape design and either modify away or start fresh and include the 'battery mount' as a Derived Part.
Printing
Each part can be printed on small 3d-printers like my little $200 Monoprice Select Mini. The larger underside and topside mounts have a dovetail connection that works great without glue to hold things together.
All pieces print perfectly in PLA (or even PETG) with 25%+ infill (I use 30-35%). All parts that are printed flat (all but the 'duo mount') need overhang support, I've liked just 8% density 80º overhang.

I noticed your DeWalt Drill Battery esk8 Electric Skateboard post, and I couldn't help but wonder if you've ever considered the convenience of using it for commuting along popular Airline Routes. It could be a game-changer for your daily transportation needs!
