We design many of our models with ‘guide holes’. These ‘guide holes’ are small holes built into each 3D printed part to allow you to align parts and keep parts together while assembling.
These guide holes can also be used to make connecting pins to hold building floors in place.
To make the locking pins, you will need:
NOTE: At printable scenery, we use the standard 1.75 filament. However, any filament will do so long as you use the correct drill bit size.
1. Insert the mini hand drill into the guide hole and gently wind it to make hole slightly bigger and clear of debris. Do this on all 3d printed parts s that will be in contact.
2. Cut a small piece of filament to a length of approximately 20 mm and then super glue one end into the hole. Repeat this for other holes and then leave to dry.
NOTE: This only needs to be done on one side of the 3d printed part that will be in contact
3. Using the side cutters, cut the each of the protruding pieces of filament to about 3 or 4 mm high.
4. You can now join the 3d printed parts together and they will align exactly.
You can use this to either help align parts for assembly or to make detachable parts that stack on top of each other without toppling.
