There are many spool holders out there. The problem is there are many spool sizes that makes it hard to build a universal one that works well. I decided to make a spool holder that mounts horizontally and uses the weight of the spool itself to keep the spool in place.
This is version 7 of my design, it’s still in progress and was a good motion study for the joints in CAD. How will it work in practice? We’ll soon find out.
I bought some cheap adhesive hooks for the shower but the were poorly designed, flexed, and did not hold up enough weight. Amazon sells a 20 pack of suction cups which I got for a variety of projects so I created these durable hooks to go with them.
Here is the file to download. All the parameters of the suction cups are variables, so if you buy different ones, just enter your specific dimensions.
The design allows for the larger round part of the suction cup to slide in, then slide up unto the smaller diameter area at the top. The bottom of the hook features a mini extension exactly the thickness of the suction cup to keep the hook perfectly horizontal and also get the most leverage from the suction cup as well.
The best orientation to print this is sideways for the best strength.
I absolutely LOVE my Class 4 CO2 Laser cutter/engraver. But it definitely needs some improvements. I’ve added custom lighting, camera, and analog milliamp reader to it and needed a control panel to manage everything. I designed this as an inset panel that controls the AC lines (which are connected to a new UPS).
My 3d printer always prints a little larger. My designs need about 0.5-1mm tolerance for fittings so I printed out this flat plate to test the panel mounted switches and hole placements.
I spend hours and hours on my bike. I needed an aerodynamic custom phone mount designed specifically for my phone/bike setup. This is my first multi-part assembly in Solidworks. So satisfying!
Before I begin, let’s stop and take a look at this beautiful bike. It’s not as high end as some of the $15k+ bikes out there, but it’s gotten me through many Ironman races.
M2 screws and nuts of varying length
I measured the diameter of my aero bars and also the distance between the stem where it would be mounted. I decided on a 3 part assembly to make it easier to print. The pieces of the assembly where designed to be held together with M2 screws/bolts.
Always used variable names in Solidworks, but also give them meaningful names so you don’t end up using the wrong measurement for the mount gap width here to account for the stem.
After re-printing the design, I pushed in the hex nuts into the slots I designed and screwed bottom mount together. The 3D printer needs a good amount of tolerance for a good fit. I used 2mm for these M2 screws but the fitting was too tight.
I custom designed in OpenScad this front of the cannon with LEDs
The back was designed to have holes exactly the size to mount LEDs in. The pieces were printed with “translucent” PLA to diffuse the light.
I found a mini helmet online and printed a small scale version of it.
This is the assembled first print. There was so much sanding that I had to do. I learned a lot about how to fill holes and smooth out the lines in the print. The support material that was broken off left so much work to be done.
Especially around the yellow lightbar the print was really rough. The post prep on this part was intense.
Did about 5 sessions of filling and sanding with bondo before I got it to a point where it was nice and round. Here’s me holding the canon. It has a handle inside. Still need to build the electronics.
