THE SIMPLEST ANTI-UNWINDING TUBE SQUEEZER

Description

I love the squeezer that I've remixed. The downside is that it requires a lot of time (& lot of filament) to be printed. In addition, it is a little bit complicated because of the ratcheting parts. I wanted to design an extremely simple one (with only 2 parts), with an anti-unrolling system but without ratchet (because of the wearing out of the teeth). PRINTING & ASSEMBLY The frame is a simple U frame, but to make it more solid I designed it flat, so that the loops, the rod (winding key) is going through, are as solid as possible. It requires some extra work after printing, bending the ends to 90° (using boiling water) but it's easy to do. Nb1: heat each end, dunking it up to the level of the V grove (all of the groove has to be in the water), and angle them to 90° using your working table surface (wait until they remain upright). If you don't want to boil & bend the flat frame, print the U version (side onto the printer's bed as shown in my CURA's screen captures) . Loops are going to be weaker, however, because of this orientation. Nb2: after you have put the key all the way through the frame, dunk the tip of the key into boiling water to soft it. Then expand the grove of the tip a little bit, so the key won't come off when pulled because the lips of the tip will limit the travel. HOW IT WORKS Pull the head of the key sliding it to stop position (it's a 6mm travel), so the hexagonal part of the rod gets out of the hexagonal hole of the frame, Roll the tube (don't pressurize it too much!), Push the key back in locking position. THE PACK INCLUDES THE FUSION 360 ARCHIVE (.f3d), so you can create customised keys; everyone of the family can have the desired style of key. Printing keys: if you are used to spools swapping, you can reveal the pattern of the logos that are embossed. I hope you can spend a minute to share your makes, specially if you print this squeezer in nice colours & with customized keys. PRINTING Concentric 100% with 4mm brim. PLA does the job.
