Description

Unscrew the knob on each side of this paper towel holder to replace the roll. The knob and bracket on the holder’s right side has a left-handed thread to prevent loosening as the paper towel roll is unrolled. During installation, the amount of pressure against the paper towel roll’s ends can be adjusted to allow one-handed dispensing.

Required Installation Hardware

(4) pan head sheet metal screws or round head wood screws, #8 diameter, approximately ¾" length
(4) #8 washers

Printing tips. Print the 2 knobs at 98% scale in the X and Y dimensions so the threads are not too tight. The knobs have a decorative center of a second color. To omit the decorative center, assign it to the same color as the rest of the knob using your slicer software.

Installation tip. The left bracket has slotted mounting holes so that you can adjust the tightness of fit to your paper towel roll.

Variations. Based on visitor feedback (thank you!), I added a profile and STL files for a taller bracket to accommodate larger paper towel rolls. I also added a profile and STL files for knobs that allow paper towel rolls with smaller inner cores (1½" or smaller).

Threading difficulties. If you experience difficulty threading the knobs for the first time, here are a few things to try. First, the right side knob-bracket pair uses a left-handed thread, so be sure the knob and bracket match and you are turning the correct direction. Second, hold the knob precisely and turn slowly at first. Finally, if the pieces thread all the way but are simply too tight, try printing the knobs at a smaller XY scale, such as 95% or 96%. Be sure to scale only in the X and Y dimensions, not Z.

Printed this and there is not a snowball's chance in hell that these threads are fitting together. Bro fix the threads and add the proper amount of tolerance so that these work! Adding a "Oh print the knobs at 98% scale" blurb is NOT acceptable and you KNOW it. FIX YOUR MODEL. This is not acceptable given how much time and filament this print takes.

I'm sorry you are having problems. I can suggest a few things to try. First, the right side knob-bracket pair uses a left-handed thread, so be sure the knob and bracket match and you are turning the correct direction. Second, hold the knob exactly perpendicular to the bracket and turn slowly at first. Finally, if the pieces thread all the way but are simply too tight, try printing the knobs at a smaller XY scale, such as 95% or 96%. Be sure to scale only in the X and Y dimensions, not Z.

@Machineabuse

Replying to @EngWorkshop :

I won't be reprinting this. Given how easy it would be to add tolerance to the threads in CAD, I cannot agree to the approach of having to fully print this again just to find a fit that may or may not work.

@EngWorkshop

Replying to @Machineabuse :

If you like, I can try to help make this model work for you. But I completely understand if you would like to stop the conversation here. While it is easy to change the design, I would need your help to figure out how much tolerance to add. In my setup, going below 98% results in threads that are too loose. Even then, there would be no way to guarantee success without your reprinting a knob (shouldn't need to reprint the brackets). The first question I would have is whether you used the posted print profile or started from the STL files.

Replying to @EngWorkshop :

@EngWorkshop Is there any way you could make the brackets thinner? like shave off 5mm off the brackets

@EngWorkshop

Replying to @Centurion3D :

I made the brackets as thin as possible. I didn't want to make them any thinner because I thought they might break during use.

@user_1359764637

I printed the brackets with my a1 mini but I didn't realize you don't have a set of knob files for the a1 mini. can you add those? I'd like to print the whole thing so it's usable.

@jejose145

same

@user_4125184144

same, why even have a profile for one model but not the knobs lol

@CoopsDesigns

if they don’t, take the model from another printer and go to Bambi studio and slice it so that it can print on the a1 mini

printed great in PETG!

@EngWorkshop

The bracket with the round holes (not slotted holes) and one of the knobs have LEFT handed (backwards) threads by design. This is to prevent the knob from loosening while unrolling the paper towels. For the knob-bracket assembly shown on the left side of your photo, you should be able to thread the knob from the other side of the bracket by turning counterclockwise.

Turned out great! I added an a1 mini profile since a lot of people don't seem to have bambu studio.

Thanks for helping out by adding the profile!

Nice setup — the print looks clean and fits perfectly into your slatwall system. The paper towel holder integrates neatly with the rest of your workshop gear, solid, practical, and well thought out.

Hi! I followed the 98% instruction and everything gone excellent. I printed the small core knobs with the tall brackets on my ender 3 v3 SE. It´s a 98% excellent design haha thank´s a lot.
