Hi,
This is a PVC pipe cover and plug,

I designed these to use for a project I'm currently making and thought that they could be useful to other people as-well. If your wanting to keep the plug / cap in place then we recommend using a little bit of pipe cement.

Solid design, No supports or rafts needed. Works as planned.
If you like the design then any support would be appreciated.

Thanks.
(This is my first design.)
