    Chocolate Rocket

    This scratch build began with my son taking a knife to a Nerf football and stuffing it into a Tootsie Roll tube coin bank - a small one. He brought it to breakfast and told me he wanted to turn it into the Chocolate Rocket. He sourced some tube fins from the Rolo candy cane tubes you see at...

    Gorilla Glue "Snot Rocket"

    My Gorilla Glue "Snot Rocket" recently made its first flight! The idea was simple - I was changing a caulk tube in my caulk gun one day and thought the business end looked like a ram-jet. From that moment, I knew I had to see one fly. I headed to Lowe's looking for a tube that had a screw...

    3D Printing Anycubic Photon Users (+other SLA's?)

    So I know that there are at least a couple of other Photon users on TRF. I've bought one and have it sitting here, but haven't even plugged it in yet. So many questions, and years of FDM printing experience don't seem to apply much. I know there's a Photon group on Facebook, and I've gotten a...

    3D Printing Just installed a Micro Swiss hotend -- fan question

    Finally got some downtime between projects and have installed a new Micro Swiss all-metal hotend for my Ender 3 Pro. (also switched to Capricorn tubing) The install was pretty straightforward, and I followed the video instructions on the Micro Swiss website. I had to adjust the z-stop slightly...

    3D Printing Good alternatives to Hatchbox PLA?

    I was going to buy some new Hatchbox PLA and see that Amazon was out of most of the colors (including the two I was looking for, of course). The Hatchbox site also shows much of their stuff as unavailable. I'm not sure what the issue is here, or if this is a long-term thing. Does anyone...

    3D Printing X-sled for 3" and 4" rockets

    Inspired by https://www.rocketryforum.com/threads/av-sled-first-printing-project-feedback-appreciated.151171/, I thought I would make a "plain" X-shaped avionics sled. No customization here, just a blank canvas for all your electronics and batteries. Sized for both 3" and 4" bays. These...
