Here is my entry. I am a volunteer ski patroller at our local mountain. Interestingly our patrol is one of the largest all-volunteer ski patrols in the US, and is one of the few all-volunteer patrols still around. We built our patrol building (which is one of the nicest patrol facilities out west) 100% with donated materials and labor and arranged transfer of the land the building sits on from the State of Utah to the Ski Patrol. I don’t understand all the legal stuff here, but it was the only way we could build the facility with donated funds.

One of the lifts requires snowmobile transfer of patients from the bottom of the lift to the base patrol building. We have been lapping our ski equipment or leaving it at the lift when accompanying patients to the patrol building. To avoid this hassle, I decided to design a ski rack for our patrol snowmobile.

It is super simple and nothing earth shattering and is a work in progress. I will have to outsource the 3d printed parts. I confirmed with the boss(wife) over the weekend that a 3d printer is not in my near future. My coworker has a 3d printer and I think I have negotiated a trade for a ski pass to print the parts.

The rack will consist of two bent plates connected by 6 round rods and bolted to the tunnel of the snowmobile with existing holes. I am planning to eventually use aluminum but will probably do a prototype with steel for testing. I included several different angle adjustable mounting locations to test out which position best locates the skis out of the way. It will double as a rack to transport gear as well, so I included several tiedown locations for bungies and straps etc.

The ski holder is a 3d printed plastic part that will be wrapped with a 1"x3/4" channel welded together in a U-shape.

The skis and bords will be strapped down inside the holder using snowboard style binding straps that should be here tomorrow.

I have had fun working on this and am excited to see it implemented into service this winter. I will get a pic when it is mounted on the sled and post it here.

Meanwhile here is a pic from last Saturday 12/9 I am the ugly one up front

appreciating the amalgamation

Who do you think reads these post? I can barely use the most basic words and you throw this out there. Now I have to look it up to see what it means. Man things are getting way to hard for me

@72Pony

snowboard style binding straps

Your post reminds me I have a old Burton kids board in my pole barn that needs one of these straps. They make a few different ones and I didn’t have luck finding it years ago. Thanks

What filament do you plan to use?

[72Pony]

I haven’t really researched the different filament types. Do you have a suggestion? I am planning on the channel frame providing the structure and the plastic just being an interface between the skis and the channel. I have considered using a plasma cut face to add some rigidity to the holder. Like I said still a work in progress.

[DonP]

Really not sure. I’ll have to do some testing.

[ds690]

TPU would be ideal, but it’s expensive and a bit finicky to print. PETG would probably be a good choice, since it’s a bit softer and more flexible than PLA.

[DonP]

Have you ever mixed PETG and TPU?

[ds690]

No. It would be interesting to see if TPU would stick to PETG as a top surface.

[ChelanJim]

ASA filament is suppose to be extremely UV resistant and strong like ABS. Would it be a reasonable option?

[ds690]

ASA requires an enclosure and the fumes are toxic. I’ve printed a few things with it and the smell is awful.

The claims of PLA breaking down from UV are greatly exaggerated. Heat is more of a concern and that is only if some deformation would be a problem.

I’ve had a phone holder printed from Black PLA+ on the dash of my truck for a couple of years with no sign of breaking down or melting.

[ChelanJim]

Did you see the sale on Amazon for the PLA+?

I don’t know what you usually pay but $17 per roll sounds pretty good?!

[DRotblatt]

I’d be concerned about the plastics becoming brittle at cold temps. I have no experience here in southern CA, but you might take some pieces of filament and put them in the freezer and see how brittle they become. Just a thought…

[ChelanJim]

I just read where a recommendation for removing threads on PLA+ prints was to put the item in the freezer, thus making those threads easier to fracture. So you make a good point.

The other point I want to make: Daniel, WHERE HAVE YOU BEEN? I still remember your post about piercing the centers of holes for a lead-in and I still use the method you came up with. By the way and FYI, there is a group of individuals working on a new Post Processor for Fusion 360 that includes a number of great features such as carrying tool settings to the post processor and it will potentially include a feature for pecking the center of holes. But that is way off this topic. If you are interested, send me a message if you want a link to that topic.

Huge life changes that last year. My mom passed away December last year (I was taking care of her here at home), and my son is off to college the past few years. I’m alone in the house for the first time in 25 years. So 2023 was a year for me to get used to life in a different way. I played, bought a Van and I’m converting it to a camper, stuck my nose into some different social stuff. All part of the process of moving forward Thanks for asking!

I made a swaging die for a 3.5" kitchen sink basket. I wanted some nice big drains that sat well below flush. I installed X4 in my XR and i am sure the die could do many more.

The dies were design in Fusion, exported as a step file to Bambu Studio and Print with 100% infill ABS on a X1C. The backing plates for also design in Fusion and cut on the XR from 1/4 mild steel.

[72Pony]

Awesome!! I have been doing something similar on a little smaller scale. I designed a ski boot shelf for my locker at the patrol building. I cut the shelf out saturday. The shelf will be on a 5° slope so the melting snow drains to the front. I 3d printed the die for the 1/2” drain hole lastnight. I just did 20% infill on the prototype
And decided to make a couple of changes. Printed another one this evening at 100% and plan to try it out tomorrow. I designed the shelf bracket to be 3d printed also. I haven’t printed one yet. Might make some changes to reduce the filament use and print time.

[ChelanJim]

I never would have thought plastic could persuade metal like that. Glad you proved it could!

That new table looks good on you. I almost caught a reflection of you on the rim of the sink drain…just kidding.
