Baby's Sensory Board Parts

Various printed components that I made for a sensory board for my son.
---
The Screw Mounts are designed to engage the screwed rod, mounting it far enough from the board that the wingnuts and standard nuts (attached to this Thing) can turn freely.
---
The board mounting hooks were designed to support the board. They screw to the side of the board (with slotted holes for adjustment), and hook over the stainless steel wire cables that form the balustrade on our deck.
