Stresstest your 3D Printer by printing this tiny collectable stocking stuffer.

Both the truck and the egg was each designed to be printed as all-in-one objects without any support structures. The truck has rotatable wheels and a tiltable bed. The egg is hinged

I'm printing this on a flashforge creator pro. PLA at 210C, 50mm speed, 40% infill and 3 shells. I used these settings to succesfully print the awesome excavator but here I have two prints already with the hinges all stuck together. What setting can I adjust for it to stick less? Lower temperature? slower printing? Should I raise the resolution to the highest setting?

Z :)

These designs prints best at 0,1mm layer height or better. If the hinges gets fused it sounds like you are overextruding. Try lowering the extrusion multiplier

I did 0.1 mm. Next time I'll try even lower and I'll lower the extrusion multiplier, let's see how it goes :)

I'm having problems getting the hinge on the egg to work. Do you have any pieces to trial different settings that don't take so long print?

By the way, what kind of problems do you have with the hinge? Does it fuse?

It seems partially fused. When I try to move it starts to move ok but then breaks apart in two pieces. This is for the egg. For the truck the dump moves ok and the wheels turn at first but then easily break off where they meet the axle

Sounds like you are overextruding. Try lowering your extrusion multiplier as a start

I lowered extrusion to 80% and hinge works good now. Thanks for your help. Truck is moving good too but the surface doesn't look good. See picture.

Hard to tell what the problem is. What kind of printer do you have? What is the nozzle size? I have 0,4mm nozzle

Qidi Xone2 with .4mm nozzle. I was watching the next one print and it looks like it's not getting good adhesion on the first layer. I am printing on blue painters tape with no glue. I was using glue directly on the table but always broke the wheels when removing.

My printer do have a acrylic buildplate so I always use gluestick. If they always breaks it might be because your nozzle is to close to the bed (that will also fuse parts). I suggest try again with glue but relevel you bed, make sure the nozzle isnt too close to the bed. The glue will hopefully provide enough adhesion

I have isolated the hinge and exported it to the following stl file. hope this helps;
(I have not tested this file myself)
Please let me know how it goes.

Here is a picture of where I've printed two of the trucks: https://imgur.com/a/leyq6. On the dump truck I used a brim and the facing down side was all connected together. On the log truck I used a raft and it wasn't glued together but the facing down side doesn't look good. On both the side facing up looks amazing. What can I do?

Try recalibrate you bed leveling. Looks like your nozzle is to close to the bed on the first layers

Maybe so I am brand new to this. Right in the middle where it is printed I have a piece of paper folded in half. It barely has some drag when I move the paper under the nozzle. Maybe this sub $200 printer just can't handle it or maybe my filmanet isn't expensive enough? I could also try playing with the temps: 195 / 55.

Unfold the paper and level it again.

It says no raft but one side of the truck is all connected together. I am having to cut along the wheel line and the truck bed line with an xacto knife. Would rafts or some different settings make a difference?

Monoprice mini v2, PLA 195/50, brim, 20% infill, speed 50, layer height .1, wall thickness 1.0.

Have you tried without a brim? I didnt use a brim

Brim is just around the outside edge, like in this photo: https://bigdanzblog.files.wordpress.com/2013/10/p1020719.jpg

I have had great fun making this entire series - and they are great for a lot of reasons.

  • The quality is amazing.
  • They are fast prints, so the kids enjoy watching it (and I can make multiples quickly).
  • They are great for showing off print in pace hinges.
  • They are excellent for getting my print settings dialed in.

Hope you make more!

Wow, thank you very much for the nice comment! It is very motivating! I sure hope to be able to make more of them and I do have a few ideas what to make next, but have not tested it yet :)
Best regards

This is awesome! Single print hinges in both the egg and dump truck. This is what I'm am showing as when people ask, what can you do with a 3D printer. I hope you can create some more of these surprise egg. Maybe something for a girl. or even more cars\trucks.

Thank you for the nice words! I hope to be able to make some more of these in the near future

I did print the car in different size. Orgional size in 0.2mm was ok to and 20-25% infil. However the tire was hard to get working normaly without they did snap off. However when I did scale the item to 1.2 that problem was solve. So if you want to print the item in little low infil and in 0.2mm I recomend scale it up little.
When scale the car to 5x of orgional size 10% on the car and 10% infil on the egg is all you need.
I did get a high qualety print of them in 0.1mm and 0.2mm :)

Wow, what a super kool idea!

You got good print results too.
I would bump your Infill overlap to 5% more than it is currently set to. That would give you a almost perfect print on that truck.

Thank you for the comment! I use "MakerBot Print" but I dont see any "Infill Overlap" setting

Which slicer do you use? Cura Simplify3d?

"MakerBot Print"

Don't know that one.. but I found this for you..

search for "percentage"

Change it to a larger precentage in my slicer I have it set to 20%

I thought "Infill Overlap" was an extended setting within "Infill". The Truck is printed at 40% Infill, and with 0,8mm roof and floor (8 solid layers before starting the infill)

This is how far into the inner most shell the infill will overlap. A higher percentage of overlap is going to fill the holes in your truck and maybe give you a near perfect Print. I am impressed how well that truck came out!
