Printed using ABS Plastic. Other plastics can be used provided that the melting point of the plastic is accounted for when blocking in felt.
Post Printing Steps
Note: The block in the following images is printed in two colors. This was a product of using the ends of two spools and is not a necessary part of the project.
1. Build a pinnable base to facilitate blocking. For best results create a two layer base with one section fitting into the depression at the bottom of the block and the second, the same size as the full bottom of the block. Particle board not recommended due to its tendency to split when nailed.
2. Glue wooden pieces together and allow to dry.
3. Adhere the wooden base to the printed block
Overview and Background
3d Printed Hat Block
This project is a reproduction of an original 1940's hat block scanned and edited for optimal printing.
This particular file has high infil and is very sturdy. However the infil can be reduced while maintaining the integrity of the block.
The product is extremely sturdy and can be used with both straw and felt blocking techniques. However, when blocking with felt please keep in mind the tendency of plastic to melt and avoid hitting the uncovered block directly with steam or touching it directly with hot tools. Steaming the hat while on the block seems to be alright. In addition, the block itself is not pinnable however, if attached to a wooden base (instructions given) it functions perfectly.
