Fold Open Travel Doll House (Magnetic)

Custom travel doll house I made for my daughter for her 6th birthday so she could take it on road trips. She painted it herself!

Designed to fit on both PRUSA i3 MK3S and Bambu Labs P1P/P1S/X1C

Magnetic, paintable, and fully customizable.

Portable and easy storage.

Case size 240mm (Wide) x 180mm (Long) x 120mm (Tall)

It's a simplistic doll house that your kid can paint and use their own imagination. No brands or predetermined colors or anything. Adding more pieces is simple.

It even comes with the kitchen sink! ;)

I printed it in ABS (for longevity and for heat resistance when it gets left in the car). Of course, I think PLA or PETG would work fine if you'd rather.

• No supports needed.
• 0.4mm nozzle
• 0.2mm layer height
• 10% infill density
• 3 wall loops for added strength.

We printed all the pieces in plain WHITE so that my daughter could paint it herself (She did an fantastic job of course!).

Family, Books, Toys, Dishes, and Food.

Sink, Countertop, and Oven/Stove.

Stairs, Bathtub, Bed, Table, and Chair.

The travel case or 'house' folds open and flat and has thin metal sheets (bought at a local hobby store) glued onto the bottoms which allows the pieces to ‘stick’ and not slide around.

The pieces have magnets inserted into them so small items can be held and furniture stays in place but can be rearranged.

Dolls can hold the plates, the food, the toys, and the books and the baby!

They can ‘sit’ in the chairs, ‘lie’ in the bed, and the tub without sliding around.

Dolls and furniture stick to the floor but can be rearranged.

Objects can stick to the countertops, the shelves, the table, etc.

Of course, magnets are optional. You could always print the pieces and skip the magnets and they still work as a small doll set.

Most of the parts have indentions for magnets to be inserted. Smaller parts, doll hands, and furniture surfaces use 3x1 mm neodymium magnets. While furniture bases and the doll's feet use 5x3 mm. (Full Bill of Materials below).

*** WHEN GLUING IN MAGNETS, TAKE YOUR TIME AND MAKE SURE THEY ARE ALL FACING THE CORRECT DIRECTION SO THEY ATTRACT AND NOT REPEL.

Assembly:

Assembly is extremely simple but there are a few things I'd caution you with.

Place each half of the case flat on a table and line up the hinges. Insert one M3 nut into each hinge indentions (you'll see). Then insert 2x M3x30mm screws. Tighten until fulling inserted and finger tight. DO NOT OVER-TIGHTEN SCREWS or you could crack the hinges it doesn't need a lot of torque. From there, use 2x M3 nuts and 2x M3x30 screws to attach the latches.

Next is gluing in the optional metal sheet for magnetizing the bottom of the case. Use E6000 epoxy or equivalent (WARNING: if you do use E6000, because of the fumes it continues to put off as it cures, you will need to let the case sit out for a week or two to allow the smell to dissipate). Cut the sheet to size with tin snips or any other method (be aware of sharp edges). Apply glue to the bottom inside of the case (it doesn't take much) and insert the metal sheet. Next, apply glue to the top of the metal sheet and insert the thin flat printed ‘floor’ piece to hide the metal (depending on your printer tolerances you may have to scale down the floor piece or clip the corners to get it to fit. Use books or other weights to hold it down and allow to cure. Allow case to sit open for a week or so to allow the glue to fully cure and the fumes to dissipate.

Next, take each doll piece, furniture, or accessory you wish to add magnets too and use a dab of glue and insert the magnets. Be sure to keep the magnets facing the correct direction as you insert them. TAKE YOUR TIME. YOU DO NOT WANT TO MESS THIS UP. To state the obvious, magnets inserted incorrectly will repel and not attract. You can't fix this later. You want all magnets to face such that all pieces work together correctly.

Then give it to your kid and let them paint! That's it. My daughter used acrylics.

I also designed a lot of picture frames and other decorations to be glued to the walls of the case (included in files) but ultimately she chose not to attach them so she could have more flexibility over where furniture goes.

Good luck! I hope your daughter smiles as much as mine did. :)

Attached is the complete 3MF file and all the individual STL files for each part.

Enjoy and God bless.
