Big Part is basic 1/2 to 1 inch thick, you need a right and left, so print 1 and mirror 1 and print again. To suspend transfer tape above flat surface to be to apply to vinyl text or graphics, upper hole is for the roll_adp that can fit the tape_roller . Vertical threaded hole is for a threaded rod 5/16 - 18, (I used all thread) must clean hole with tap.

Clamp_top and knob are 5/16 - 18 also used to lock down the big part of the clamp, put threaded rod thru big part first than clamp_top, I used a 5/16 - 18 nut as a jam nut against the knob to stop it from coming loose when operating screw.

Tape_roller fits standard roll of most any transfer tape on market unless noted, this is a snug fit. ***Note: If you have to beat this in to the end of your tube your probably not getting back with out cutting it out...you'll get what I mean if it happens to you.

Good luck, If you put in the time, It will save you money.

Recommend 40 mm/s print. 10% infill. Recommend Adhesion -Brim- parts may peal without.

Update -- As you can see from the photo I am masking a sign that is 18 x 24. I have the tape roller sandwiched between the cutout for the table leaf, these works great, pull the tape over and stick to table surface first, than run a straight edge down the center to toward the roll and stick to the table. work the air out form the center outward and you will have a masked project..pictured is a 12" roll of tape.
