protective caps for Softube-Whirlpool

We have had a Softube hot tub for some time. However, as electricity prices have risen sharply, we decided to dismantle the motor unit over the winter and drain the water. It turned out that the connections on the pool were open and unprotected and that protection and insects could get in. I therefore printed protective caps for the connections. 
If I could help you with this, a short feedback would be great.
