Kapton Tape spreader frame

thingiverse

This Kapton tape spreader frame ensures easy application of large expanses of Kapton tape without bubbles or wrinkles. To create it, gather four small or medium clothespins, four thin elastic bands or hair bangles, and four custom-cut 5/16" or 8mm dowel rods or threaded rods. Print the four corner parts or create simple wooden blocks instead. Clean out the holes with a 8mm or 5/16" drill bit and small screwdriver or drill bit for elastic holes. Cut two rods to the width of your tape plus 4 inches, and the other two rods to your desired length plus 4 inches. Attach elastic bands to clothespins and push them through small holes. Assemble the frame using friction, allowing for disassembly. To use, unroll an inch of tape, clip two clothespins to corners, and continue until all four clothespins are in place. Ensure elastic is under tension to keep the tape flat. Apply the tape using either method 1 or 2, both of which involve using a plastic card to remove air bubbles.
