monster toy picker-upper - 5mm polycarbonate sheet
Monster toy selector
It's time to clean up the toys, did you hear moaning and moaning? . . . . "Do I have to?
"Well, don't let your kids pick up their toys and let the monster toy pickup up their toys!
This little device has a colorful tongue that rotates as the monster rotates around the floor.
The tongue sweeps the toy into the belly and is ready to throw the toy wherever it is stored.

The two wheels are the same, but only one wheel drives the rotating tongue. (
So the monster can make a sharp turn.
Otherwise I need a differential as the two wheels will be locked at the same rotation speedi. e.
Travel straight. )
The wheels have internal teeth, and there is a small straight gear on the rod leading to the sponge.
The wheel is mounted using a 5/16 "x 3/4" Hex bolt that is screwed into the disc of the PVC sheet and the center drill has a 1/4 hole that is glued to the body.
The bolt is actually cutting the thread into PVC.
Washers are suitable for both sides of the wheel. The non-
There is a small plastic cap on the drive side to capture the end of the rod (
Like a straight gear on the drive side).
The lid and the straight gear are attached to the rod and fixed in place with super glue.
Provide washers on the drive Bar on both sides of the body.
Thank you very much Zach Hoeken, who posted planetary gears on the Thingiverse based on my gear system: planetary gears released by hoekenPublished on November 8, 2008thingiverse.
Com/things: 53 The tongue is made of a normal household cellulose sponge (5/8" thick)
Cut to about 1-1/2" x 3".
The sponge is fixed on the drive rod through the "sponge Holder (
What novel name)
As shown in the figure, the sponge holder is printed upright.
45 degrees 'V '(vault)
The bottom allows printing without a bracket.
The V at the top is symmetrical.
The sponge holder has a gasket at each end next to the body that slides onto the drive rod.
There is a diamond cut on the side of the sponge holder.
This allows access to the drive rod when installing all the sponges and apply hot glue or epoxy to the diamond, fixing the sponge holder on the rod so that it does not slide.
The main body is 1/4 "PVC (foamed)sheet.
It's really easy to use it, no painting is needed to complete this project.
It is very easy to combine and can be treated in about 15 minutes using PVC pipe cement.
The body consists of the following parts :(
Refer to the label identification component on the photo)[
I 've been using the metric system since I used 3D printing, so I cropped the panels in millimeters
Please apologize if this makes anyone feel sad. ]
Left and right panel (identical)
200x350mm rear panel 185x190mm front and rear handle panel (identical)
185x70mm at peak time (
30mm straight edge)
185x205 bottom plate 185x260 front panel 200x242mm at peak time (
200mm straight edge)
I think a good stake will be a good handle.
It is fixed between the front handle panel and the rear handle panel;
The two panels that make up the toy tray collect the toys that escape the "monster.
Pins with a diameter of 3/4 are comfortably mounted between the two panels and captured by two rings made of 1/4 PVC sheets.
The ring is just a 1/4 PVC sheet with 3/4 paddles drilled on it.
The ring slips through the pin, the pin slides into place, and the ring sticks in place.
Because it's a monster, I think it should look a bit threatening.
I chose to give it a bunch of pointed teeth.
I just marked the tooth pattern on the front panel (face)
Cut them off with a band saw
The wheels printed in 3D are smooth, so they need to be modified to enable them to grab the carpet and the slippery floor (i. e.
Tile and hardwood floors.
I decided that an easy solution would be to take some anti-slip shelf liner and cut it into long thin strips to stick around the wheel.
I took a straight blade and a razor and used an old carton as a cutting board to cut the rubber lining into thin strips.
Then I fixed them around the wheel with epoxy glue.
I used a crazy way to do this.
I ran a circle of epoxy on a piece of cardboard and then rolled the wheel along the epoxy coating to the circumference.
I then placed a thin liner on the "wet" wheel.
The liner is almost exactly the right length to go around-
To fill in the blanks, I just need to add a small clip of 1/4.
My original design was to get the toy stuck between the sponge and the bottom plate (
45 degree cutting).
I can't really get the baseboards closer to the floor, or it may drag and they may not be able to touch the floor properly if the wheels sink into the carpet.
I decided to put a spoonful of polycarbonate on the floor.
The scoop is 1.
5mm pc 180x190mm.
It has a slight downward bend so it touches the floor.
It is loosely secured at the back with two screws, allowing it to play vertically.
I decided to bend the paper and clip each half onto the wood strip with a gap between the places I wanted to bend.
I used some aluminum foil to provide a head shield for may spring clamps.
After some patients heated the plastic began to collapse and I got the bend I wanted.
Two mounting holes were drilled at the far end of the plate, and two sheet metal screws of 6x3/8 were used to mount it on the bottom plate.
I keep the screws loose so the sheets can slide up and down so the tip of the screw doesn't go through the bottom plate.
My "fix" success is limited. . . . .
My Monster toy picker
Upper is not so hungry. Its not eating.
As noted in step 7, the toy has been stuck at the bottom of the unit and on a polycarbonate board that has been added to correct the problem.
So I would say that although the concept is simple and the monster looks cute --
It does not work well. . .
Really, not at all. :-(
Some Lessons Learned: 1.
The sponge seems to need to be longer or more flexible, so that if the first touch, the toy does not enter the "sponge" or the new flap will flip it and will not plug it into the bottom of the device.
Currently, the sponge will pin the toy to the bottom plate or polycarbonate plate and prevent the tongue from spinning. 2.
The drive train needs to be stronger or at least fine-tuned in order to run smoothly.
The 3D printing gear works but hangs occasionally
Sometimes here too.
They run very well, but they are often hanged.
This may be related to the operation of the wheel on the axis.
Wheel mounting is OK but may be better.
If I thought the "monster" would be overused, I would probably explore the real orientation. 3.
I had a great time designing and printing the "sponge.
I have more experience in Fusion 360 and 3D printing.
They did a good job and did exactly what I meant. 4.
PVC sheets are good to use.
I found it on a 1/4 thick 2'x4' sheet at Home Depot for $15.
It allows the use of woodworking tools, quick bonding with PVC cement, no painting is required.
I will have to use it in some future projects. 5.
The non-slip drawer liner on the 3D printing wheel works well.
This combination is very effective.
The wheels do not slip on hard floors or carpets.
It's also easy to assemble.
So the concept is fine, but some additional experiments and redesigns may be needed in order for it to work properly.
I am still very happy to make this manual and have learned something!
I hope you did the same.
Thanks for reading!
