A further development of my project Bedside Lamp "Tube", but because of the two light sources with of course a double light output (with 2x 250 lumens). With 3000K the light is considered warm white. The power consumption is 2.5 watts for each LED...

There is no HEPA filter, as that would likely require stronger fans/a thicker filter, so it won't filter out potential microparticles, but the active charcoal will filter outgassing from ABS/ASA. The bottom of the rails (20 mm wide) work well as...

(The sheet I designed also contains an M2 screw with a corresponding M2 nut.) You should also have double-sided adhesive tape in your assortment to stick the yellow face on the helmet and glue with which you can glue some of the printed parts....

To do this only connect one of the colored wires going into the driver and combine the two colored wires from the lamp to the one colored wire on the lamp.The high level process is:Check the length of the COB Led against the mount and cut it where...

A ring around the split antenna hole is also left smooth.You can see the wall perimeters get ‘doubled’ at the fuzzy region as a consequence of Prusaslicer adding walls around each modifier region. In this case it just needs to be understood that with...

I needed it to be higher than the ground in order for the food to fall into the bowl, so I made a stand for it, which also doubled as a container for the electronics, and a spout to clip onto the bowl. I ordered a continuous rotation servo for this...

The length of the piece of string should be approximately double that of the distance between the hooks (that way, it is easier to tie).    3b) Tie the piece of fishing line using square knots (left over right, right over left). Optionally, to ensure...

 As always, measure twice (even thrice or more!), make sure you have marked out where you want to cut, use a decent steel ruler and when you are happy with the outline, use the ruler with the cutter butted un to it and adjust the position, check...

Disable overscan, pixel doubling, and screen blanking. If you have not enabled the camera interface, do so now. Enable SSH, VNC, SPI, I2C, Serial port. Optionally you can set the desktop preferences: uncheck wastebasket and mounted disks, and...

Using the two BandToStringLoops, feed one end of the string through the smaller hole of the BandToStringLoop, then double knot it so it cant be pulled through the hole. Do the same for the other end of the string such that the length of string is...

ONE SIZE FITS ALL FOR THE INTENDED PURPOSES OF THIS PRINT IT'S ESSENTIAL TO SIZE THEM CORRECTLY FOR ---YOU---Note: 2 Options for a .stl and .3mf are listed one in a smaller size one in a larger for those of you who are too lazy to scale the print up...

Remember the double sided operation requires precise work holding for WCS. You can fashion a makeshift machinist square by gluing two small pieces of wood together to form a 90° angle. Alternatively, you can use the reference pin method. There are...

There is a thin layer of black foam double-stick taped to the bottom of each foot. The corner feet are retained by M4 screws with T-nuts, and the gantry feet slip on. Simply put, it’s the bottom half of an AM8-MGN12-BLV build, just still wearing...

 Double check all your calculations (maybe have a friend re-do them separately too) and be careful.Assuming you're drying PETG, tune the power to the boost heater to barely reach 60-65C.  If you start to hear the dryer's relay clicking to...

It can be repaired with glue and didn't interfere with its ability to form a board, but between that and the dents left in the mould by the clamping process, I would suggest considering a higher infill than I used (which was 20%) and/or a greater...

 For me, it was easiest to completely mount the double support first on one segment and then screw it to the second later on. ...

If your also using the extension arm double the quantity of items #5, #6, & #7. Pre-assembly: Step 1: Read the warning & design sections in the description before beginning. Step 2: Print the necessary parts. There are currently five sets of files. I...

(a 5mm Brim may be needed for the AXLE and RIMS as they print much taller than they are wide) -- COLOR CHANGES Specific Layer and Height in mm for each color change on each part, (NOTE using PrusaSlicer, Changes occur BEFORE the selected layer...

If you are printing the two-part handle, I would strongly recommend doubling your default extrusion width and using an infill of 20%. Unless you are extremely confident in your bed adhesion, I would not print the handle with the main box, The handle...

If another dimension is needed, bigger or smaller, the model can be scaled on one axis. I use it for a MacBook Pro 16'' 2019 that is 16.2mm and added two 1mm adhesive foam sheets, one for each side, that added to approximately 18.2mm so it has...

if you opt for the 4020 double fan version you will also need 3 additional M3x18 screws in addition to printing the extra part. 10.Attach the top piece that holds the cable tube with 2 M3x20 screws to hold the tube and the platform to the carriage...

You may want to use some double sided tape to hold it in place and put the motherboard atop to see if the holes line up. If so you can apply some glue around the edge to hold it in place otherwise reposition and try again until it lines up. Leave to...

Obviously I expect it to work now, but have not had time to test it with another print before uploading to this competition, so fingers crossed! If the clips don’t work well then double-check that the electrics are working, and then glue the front...
