POLYmount - The Ultimate PolyDryer Snap-In Wall Mount

Tired of broken wall mounts? Meet the wall mount your PolyDryer actually deserves!

If you're like me and love your PolyDryers but found yourself frustrated with the original wall mount being difficult to use (and worse, breaking over time), say hello to the POLYmount!

What Makes This Special?

This is as usual truly overengineered in the best way possible:

• 💪 Built to last - No more broken mounts! This design actually holds up to daily use.

• 👆 One-handed operation - Attach and remove your PolyDryer with ease. Because who has time for two hands?

• 🔧 Fully tunable - Complete set of springs included so you can adjust it exactly how you like it. Want it playful? Want it strong? You got it!

• 🧲 Optional magnets - Add even more snap to your setup, or stick with the printed springs only that work (almost) just as great!

• 🔄 Drop-in replacement - Keeps the main design and mounting points of the original, so installation is a breeze.

• ✨ Addictive - Seriously, if you are like me, it's so satisfying you'll find yourself taking your PolyDryer down just to snap it back in again!

• 📐 CAD files included - Want to remix? 👉 Go wild!

Model Details

Slider Travel Limit

The slider features an ingenious print-in-place mechanical end-stop that prevents over-extension, protects your springs from damage and gives you the feedback you want when removing the PolyDryer.

• ⚙ Perfectly calibrated - The travel distance is precisely set to allow full PolyDryer insertion and removal.

• 🛡 Spring protection - No more worrying about over-tensioning and breaking your springs, even with enthusiastic use!

• 🔧 Print-in-place genius - The limit mechanism is built right into the slider and breaks free during assembly. No extra parts and no supports needed - it just works straight off the print bed.

• 🔓 Easy release mechanism - The slider includes an integrated release option that lets you remove it with ease. Want to swap springs or just experiment with different configurations? Here you go!

Spring and Magnet Configuration

👉 Quick and dirty with not much details 

• Option 1: Use Magnets plus Spring Single - 6 2-0 - 0-3 (preload 0.3) printed in ASA

• Option 2:  ... no magnets but a Spring Twin - 9 1-6 - 0-6 (preload 0.6) printed in ASA

... but make sure to print at least one complete set and play around 😎!

🔎 But I'm sure you want some details

• Single vs Twin Spring Profiles: Twin-Springs are stronger and will provide a rather linear characteristic in this setup. But if you opt for magnets you can go with the Single Springs for a more snappy feel and constant spring tension.

• Diameter: The thicker the spring the more tension it will have.

• Spring Shape: Fewer coils will be stronger but also slightly more "demanding" for the material. For the Single Springs this should not be a problem, but for the Twin Springs choose wisely: The more brittle the material is, the more coils the spring should have to prevent plastic deformation.

• Preload: The initial compression/tension built into the spring. Using magnets, go with rather low preload (0.3mm for ASA); without magnets you want a bit more (0.6mm for ASA) to keep things preloaded. If you're using a more flexible filament, play around and increase the preload. Of course there is a user parameter in the Fusion project to change the preload with ease.

And if you have some better ideas: That's what the Fusion project is for! 😎

Assembly 🔧

It's as simple as it seems, just a few things to know before we start:

The parts	... and what to look out for:
	Inserting the magnets: The magnets in the base do not sit flush with the surface, they will stick out ~0.4mm of the surrounding surface but below the surface for the rails for the slider.  Use a second magnet as helper (see pics). The magnets in the slider do sit flush or ~0.2mm below the surface. Use the tool to not damage the part.  Just make sure the slider can move freely in the base and the magnets to not interfere.
	Inserting the Spring: Make sure to fully insert the spring into the slider, e.g. by pressing it firmly against a flush surface (see photos below) However, the spring will stick out ~0.6mm by design as seen in the picture It's a press-fit and it will hold things aligned during the assembly.
	The Springcover: It's a really tight press-fit joint, this is by intention for this small part to sit wobble-free. Inserting will scrub-off some material from the stand-offs of the cover part! To insert it, it might help to slightly tilt the cover and first insert it on one side. If you want to remove it, there is a small gap between the spring and the cover where you can insert a screwdriver The cover can eventually break when removing it, don't blame me for that, just print some spare covers right from the beginning ... and while doing your first spring testing, just do not add the cover but wait til you decided for your spring setup.
	The Screwcover: It's a press fit joint, but not as tight as the Springcover. There is a version with notches on the side to easily remove the cover by using a screwdriver ... or if you are like me - always sure things are correct - use the cover without notches for a clean look (and use a sharp knife later to get it off 😂)
	Smooth Sliding Surfaces: Surfaces marked in blue are the ones where the Slider / PolyDryer will glide on. Make sure they are smooth!

Build Steps

And now, let's have some fun and follow the pics ( click pics to enlarge 🔎)

Seam Placement ⚠

The 3D printed springs will withstand all the load in this application, but you have to tell the slicer to avoid a seam anywhere in the read area. Just place the seam manually (the little green line) and you will be fine.

Support Settings

All parts are designed without the need for support or come built-in support in case of the base. It uses a sacrificial layer that breaks away in seconds so give it a try. And just in case you want to let the slicer do the magic, the base is also available without the support block and sacrificial layer.

Print Settings

And as usual for mechanical parts, let's go with with the standard Voron settings. That's what the parts are designed for:

• Layer height: 0.2mm

• Extrusion width: 0.4mm

• Infill: 40%

• Perimeters: 4 walls

• Top/bottom layers: 5 solid layers

• Supports: None required - all parts are designed to print without supports or have integrated ones

• Material: ABS or ASA recommended (but feel free to experiment with PETG or other materials)

BOM

• Optional but recommended:  4 pcs. 3 x 6mm magnets ... for that extra snappy feel 🤩

• Screws for wall mounting : 2pcs. 4mm diameter

That's it! Everything else is printed.

Team Effort ❤

Big shoutout to @fe4rnandez 🥰 for making this happen! This was a true collaboration - bouncing ideas back and forth, iterating on concepts, and pushing each other to make something awesome. But without him starting to reverse engineer the original mount and sharing the CAD files (and me pushing him down this rabbit hole 🤣)  this model would not exist. Make sure to check out the PolySnap 🤩 too - rumor has it he's still cooking up improvements!
