THE STORY

Healthcare workers ran across this article on Facebook and inquired about the possibility of printing them locally. Finding the file on Thingiverse and after a quick test print on “Groot” the go ahead was given for 150 copies. The nine Ender3’s were called into action printing 5-up at a time to crank out 200 in the space of a couple of days. PLA was used in multiple colors. A yardstick was recycled and 3D printed end pieces in ABS made it easy to keep track of production by counting the color bands. A single lime green strap marked the 100 position. 

The inspiring Facebook article and the resulting initial lot of 150.

THE REST OF THE STORY

After removing so many clips from both glass plates and polymer skins some embellishments were conceived. TinkerCAD to the rescue. A name was embossed as well as a little dent in the bottom surface for easy removal.The tweaks were then exported and re-sliced in Simplify3D.

Here’s a shot of the Ender3 “Printer Farm” in action.

3D Printing Projects 202001 – Backup Camera Mount

TRON getting in the act!

This project extends the phone holder that attaches to the air vent in the dash to include the wireless backup camera viewer. The part was designed in SolidWorks, sliced in Simplify3D and printed in PLA on TRONzilla. The pocket was a little tight so another version is in the works as well as maybe moving it a little more forward. Worked good on its maiden voyage on an 11 hour road trip.

3D Printing Projects 201334 – Door Knob Keys reminder

3dkeysSomeone was using a post-it note to remind themselves not to lock the keys in their office. We came up with a catchy solution. The round ring provides just enough friction that an adhesive was not needed. No sanding either!

The part was designed in SolidWorks and printed in ABS.

3D Printing Projects 201333 – UNEF Threaded extension

MB_3420A friend of min was having trouble sourcing quickly a fitting for a faucet project. The unit had a 3/4 – 20 UNEF (extra fine) thread. We looked up the threads specs and printed a couple of trials. The threads engage nice in general. There is a little swelling at the base where the part sits on the heated bed.

The pipe was designed in SolidWorks and printed in ABS.

3D Printing Projects 201332 – Rostock MAX upgrades – fan plugin

MB_RMfanThe fans for the Rostock come with tiny micro Molex connectors. The spacing is smaller than standard 0.1 inch header spacing. Wanting a sturdy end to the power festoon to the hot end a block was developed that engaged into the top mounting ring. Besides dowels that plug into the existing top plate a round cavity allows for a commercial strain relief to bring the power wire from the stationary part. A couple of square holes allow for plugging in of the micro Molex connectors. Wire was used to make pins guided by holds printed in the block. A groove to interlock the connector orientation was printed as well.

The block was designed in SolidWorks and printed in ABS.  Now the fans can be plugged in and the connection of the power wire to the hot end securely fastened.

3D Printing Projects 201331 – Rostock MAX updgrades – cooling

MB_RMcoolingIn getting the parameters dialed in for printing PLA a cooling ring is envisaged to cool the extruded material as it leaves the hot end. This mounts to the bottom of the Rostock Max extrusion platform. Internal baffles and differing size exit holes work to equalize the pressure to make a 360 degree cooling zone. A 25mm fan blows air from the side and gets directed to the printing interface. Eventually a set of clips will be integrated to clip on the axles of the delta unit.

The shroud was designed in SolidWorks and printed in ABS.  Once the shroud was in place a connection had to be developed for powering the fan. See later post.
