The reason for it looking like it won't fit the bed is because I had the skirt enabled in Cura. Just disable and you'll be fine. Disregard my previous comments. Still new to this ;)
This is the first thing I have ever designed. I made it in Tinkercad.
A little backstory:
For Christmas this year, I built a toy chest for my 3 year old nephew out of reclaimed wood, and bought him a Nerf blaster to go with it. I wanted the top inside of the chest to display the blaster for him, so I came up with hangers that will hold it even when the lid is closed. (These are easily removable so he can use the chest for whatever else when he gets older.) However, when it came to holding the darts, my first thought was to just use the packaging they came in and screw it into place. But I'm not happy with how it looks (Nor, the placement).
I couldn't find anything for "wall mounting" Nerf darts, so I decided to create my own and post it here for any and all to use.
I printed this with a skirt on my Ender 3 Pro. It came out fine, however, it is a little long. So, if you're using Cura, push it back on the bed more than you think to get it away from the front edge.
I noticed that the print was a lot closer to the edge on the actual Ender bed than it was showing in Cura. I have Cura's Ender bed pictured with the location I printed. It should print well if you follow along.
**At the time of posting, I hadn't yet taken pictures of the chest with the dart holder installed. So, if you see the darts held with a clear plastic housing, that's the "before" photo.
I would like to start designing and creating more things. Finally give back to the community I have taken so much from. You are all an inspiration.
